Aside from that, you will also learn plenty of interesting things about the power push button switch that will help you understand more about how it works in its most common applications.

So let’s start discovering everything about the power push button switch and become a wiser consumer today.

1. What is the power push button switch?

Power push button switch

The power push button switch is a distinct kind of switch because of the power symbol that’s engraved or laser etched on its head.

There are other terms that refer to the power push button switch such as power push button, push power button, push button power, push button power switch, button power switch, push power switch, power switch button, or power switch push button.

It is specially manufactured to be a power switch button that triggers the start of any operation in many applications.

But just like the other standard push button switches; the power push button switch has many kinds and different configurations to accommodate your different application needs.

Manufacturers understand that consumers like you need to have numerous options of power push button switches hence they offer different variants and specifications.

The different descriptions below can help you when choosing the right power push button switch:

• Diameter size — You can find sizes from 8mm, 10mm, 12mm, 16mm, 19mm, 22mm, and 25mm up to 40mm or bigger diameter sizes that can be requested from the manufacturer.
• Shapes — The power push button switch is typically round shaped but you can also find square-shaped power push button switch as well as low profile or miniature types.
• Colors — You can find many different colors of the power push button switch such as natural, chrome, white, red, blue, black, green, orange, gold, and so on.
• Types of terminals — The most common pins you can find are the screw type or solder lug but you can also find flying leads, blades, or feed-through types.
• The shape of the actuator — The actuator or the head also has different shapes like flat, raised, domed, concave, chamfer head, or squarehead and all have the power symbol either embossed, engraved, or laser etched.
• Illumination type — The power push button switch generally has one illumination type which is the power symbol but sometimes it is combined with a ring surrounding it and both are backlit illuminated.
• LED colors — You can also find varieties of colors which can be a single color, bi-color, even tri-color, and these single colors or color combinations are green, blue, red, yellow, orange, white, and so on. These switches are labeled with the “LED” term, for example, LED power switch button, LED with push button, push button com LED, power switch LED, power button with LED, power switch with LED, or RGB power button.

There may other parts that are not included in the list above but these parts are the most common and can also be easily remembered when you are shopping for the power push button switch.

2. What is the story behind the power symbol of the power push button switch?

If you wonder how the power symbol you see in the power push button switch came to be, there’s a story behind it.

In the early times, the toggle switch was used as the power control switch.

It has two physical positions for the «on» and «off» functions respectively.

Eventually, the terms “on” and “off” were replaced by symbols as the technology becomes widely used.

These symbols are “0” for on while “I” for the off function.

The circle and a bar or line you see in the power symbol today, are from the concatenation of these symbols.

To explain this logically, the symbols represent the binary states, 0 and 1.

The zero “0” also indicates that the circuit is open while the line indicates a closed circuit.

The power push button switch has these two symbols because it can switch “on” and “off” the circuit.

In a toggle switch, the “on” and “off” symbols represent its two states.

The International Electrotechnical Commission has treated these symbols as a standard worldwide.

The “I” and “O” symbol is a widely accepted symbolizing the power switch and it is a symbol that simplifies its labeling since there are many different electrical and mechanical configurations.

The power symbol became the accepted indicator regardless of the form of a mechanical switch, whether it is a push button switch type, toggle, slide switch, etc.

Fun Fact: The power symbol isn’t as powerful as you think

In 1973, the IEC released the universal graphical symbols where the power symbol was used for the “standby” mode (IEC 60417-5009) and also indicates that the equipment is on sleep mode or drawing a low power.

However, since it has become confusing for consumers to understand the exact meaning of the symbol until you try pressing it, the waning moon symbol was proposed to become the standby mode instead.

The IEEE and CEC published the IEEE 1621 with these changes back in December 2004.

Therefore the power symbol that you see on the power push button switches was originally used for sleep mode but now it is used to indicate that the equipment is “waking up” rather than sleeping.

Evolution of power push button switch symbol

3. What makes up one unit of the power push button switch?

You could be familiar with some of the parts of the power push button switch since it has the same parts as the other standard push button switches.

But there are other parts and sections of the power push button switch that are good to know just in case you need to name a certain part that is missing or maybe needing a replacement.

Listed below are the general parts of the power push button switch:

• Button or actuator — This is the head of the power push button switch where the power symbol can be found.
• Body or shell casing — In a more technical term, this is the enclosure of the power push button switch that “encloses” its internal parts and keeps all the parts together in one single unit.
• Terminals or pins — These are the metal electrical conductors attached at the bottom of the power push button switch where wires are connected and can come in with two up to 6 or more depending on the type of switch.
• LED or illumination — This is responsible for how the power push button switch emits light whether when it is “on” or “off” depending on how you wire it and it comes in different illumination colors.
• Hex nut or the mounting flange — This piece of hex shaped round metal is used to secure the mounting of the power push button switch by fastening it through the back or front depending on the type of switch.
• Rubber ring or O ring -This rubber material seals the clearance beneath the head of the power push button switch and the panel surface to prevent any elements from entering the back of the panel.
• Grooves -These are the depressions along the body of the power push button switch that helps the mounting flange tightly secure the switch.
• Stationary and movable contacts — These are made from conductive materials that are positioned inside the power push button switch.
• Coil spring — This allows the actuator of the power push button switch to compress when pushed and helps it bounce back to its original state when the pressure is released.

3. What color is recommended for the power push button switch?

Although for your DIY projects or your personal use, you can freely choose whatever colors you would like for your power push button switch.

However, if you will be using it for applications such as pieces of machinery or control panels, you may be required to comply with the IEC6004-1 or the Electrical Safety of machinery.

This requires that push button switches with start or connect function should have the colors green, white, black, or gray, and red is not acceptable.

If it is going to be used for an operation that starts when pressed and stops when the button is let go, it is required for the power push button switch to have either black, white, or gray color and the colors green, yellow, or red are not permitted.

For a reset function, the power push button switch should have the colors black, white, gray, or blue and if it is also used for the stop and disconnect function, the same colors are required except for blue.

If the power push button switch will have an alternate function such as start or on and stop or off, the colors mandatory are black, white, and gray while the colors green, yellow, or red is not allowed.

4. What are the ways to wire the power push button switch with LED?

You can wire the power push button switch with LED in two ways.

When you want the LED to be always on, and when you want the LED to only light up when you push the actuator of the power push button switch.

For instance, you have a 5 pin power push button switch with LED, and you want to wire it where the LED is always on regardless of whether it is turned «on» or «off».

The same rule applies to the illuminated power button, illuminated power switch, or lighted power switch.

Here’s how you can wire an always “on” power push button switch with LED:

1. Wire the NO to the “+” to the device.
2. Then another wire to connect the “C“ pin to the power source.
3. And a separate wire to connect the “-“ for ground.

But if you prefer to only have the LED “on” when you press the power push button switch, here’s how you can wire it:

1. Wire the NO pin and the “+” pin to the power source.
2. 随后，用一根单独的导线将«C»引脚连接至设备。.
3. 接着，再用一根导线连接至“-“引脚以接地。.

您可能会注意到，说明中的唯一区别在于NO（常开）引脚和正极引脚的连接位置——无论是连接电源还是设备，这会改变LED的点亮方式。.

通常，订购电源按钮开关时，您会收到针对所购开关型号的专用接线说明。.

如果没有，您可以随时联系制造商获取接线说明副本，或重新访问其网站——如果他们在产品列表页面上发布了接线说明图。.

电源按钮开关的不同应用

7. 为什么电源按钮开关在电路中有不同的符号？

在电路中，您可能会发现代表电源按钮开关的符号存在差异。.

您可能会疑惑，既然它们都代表同一种开关，为何会有不同。.

这是因为尽管名称相同，电源按钮开关在极点和投掷数方面存在不同配置。.

极点和投掷数指的是开关触点的不同变体。.

极点是指连接或属于某个电路或负载的一组电气端子或触点。.

投掷数是指开关可以接通的位置或接触点。.

电子行业对这些术语进行了缩写，以便轻松识别开关类型，它们分别是：

• SPST电源按钮开关

其全称为单极点单投掷电源按钮开关。.

它也被称为简单通断开关，在美国布线名称中为双向开关，在英国布线名称中为单向开关。.

它有两个端子，可以连接或不连接任何电路。.

• SPDT电源按钮开关

这是单极点双投掷电源按钮开关，在美国称为三路开关，在英国称为双向开关。.

它也被称为简单转换开关。.

• DPST电源按钮开关

这代表双极点单投掷电源按钮开关，相当于由单个电源按钮开关单元控制的两个SPST开关。.

• DPDT电源按钮开关

这被称为双极点双投掷电源按钮开关，相当于由一个电源按钮开关控制的两个SPDT开关。.

8. 电源按钮开关是瞬动型还是保持型？

电源按钮开关两种类型皆有。.

您可以找到瞬动电源开关或锁定电源开关（有时称为保持型）等类型。.

例如，瞬动电源开关PC。.

了解您需要哪种开关动作非常重要，因为它们彼此差异很大。.

以下是关于电源按钮开关两种开关动作的简要说明：

• 瞬动电源按钮开关

在这种开关动作中，当您按下电源按钮开关的按钮后松开，按钮会弹回原始状态。.

例如门铃、汽车喇叭、汽车电动车窗控制、装卸设备控制等。.

• 保持型电源按钮开关

这种开关动作也称为锁定或闩锁式。.

在此类开关中，当您按下电源按钮开关时，它将保持按下状态，只有在再次按压时才会弹回原始状态。.

此类开关的示例包括电灯开关、手电筒开关、音频设备组件以及其他需要保持式开关动作（而非瞬时式）的应用。.

音频设备上的电源按钮开关

9. 电源按钮开关有哪些安装方式？

电源按钮开关主要有三种安装样式，分别为：

• 面板安装式电源按钮开关

电源按钮开关或面板安装式电源开关安装在面板上，因此得名面板安装。.

在计算机应用中，它也可称为PC安装式按钮开关。.

这种安装样式下有两种方式，即最常见的后面板安装和前面板安装。.

后面板安装是指将电源按钮开关安装在面板后方。.

这意味着安装法兰从开关背面（即安装面板的后方）插入。.

而前面板安装是指从面板前方安装电源按钮开关。.

如果电源按钮开关的执行器周围有凹槽，则可轻松判断其为前面板安装类型，因为此处是安装法兰的固定位置。.

• 表面安装式电源按钮开关

在此类安装中，电源按钮开关安装在表面或PCB（印刷电路板）上。.

通常，采用这种安装样式的电源按钮开关为薄型或微型设计。.

• 齐平安装式电源按钮开关

在这种安装样式中，电源按钮开关安装在表面上，并与表面齐平，从而提供更好的表面间隙。.

在此安装样式中，您可以选择安装开关帽，以为电源按钮开关提供更多保护。.

10. 为什么现代电子产品使用电源按钮开关而非摇杆或拨动开关？

大多数现代电子产品使用电源按钮开关而非其他类型的开关，这纯粹是出于实用性考虑。.

摇杆和拨动开关通常比按钮开关更昂贵。.

它们也广泛用于主电源开关，因为安全法规对此有更严格的要求，否则主电源将无法通过安全认证。.

您可能会在计算机中看到这两种类型的开关。.

在计算机系统单元的前面，您可以找到电源按钮开关，而在后面则会发现控制主电源的拨动开关。.

电源按钮开关的功能是开启计算机，而后面的拨动开关则保持电源供应运行，除非将其关闭。.

电源按钮开关也称为计算机按钮电源开关、PC按钮电源开关、PC电源按钮开关、PC电源开关按钮、PC电源开关、PC电源开关、PC电源按钮、PC电源按钮、PC开机按钮或电源按钮开关PC。.

您还可以找到定制类型，例如定制PC电源开关、定制电源按钮、定制PC电源按钮、定制PC电源开关或定制计算机电源按钮。.

11. 为什么现代计算机只有电源按钮开关，而不像其前代产品？

您可能已经注意到，如今的台式计算机前面只有一个按钮，即电源按钮开关，而不像大多数旧版本计算机那样还有一个复位按钮开关。.

计算机制造商认为保留电源按钮开关并移除复位按钮更为合理。.

因为复位按钮的功能是重启计算机，这与电源按钮开关的主要功能（即启动计算机）似乎冗余。.

尽管存在细微差别，制造商仍决定坚持他们的决策。.

虽然复位按钮非常有用，尤其是在计算机死机时，您只需按住复位按钮等待计算机重启即可解决问题。.

使用电源按钮开关时也是如此。.

如果您的计算机完全死机，您也可以按下电源按钮开关来重启计算机。.

然而，如果您不喜欢这种设计，至今仍可以找到生产带小型复位按钮系统单元的计算机制造商。.

带有电源按钮开关和复位按钮的计算机系统单元

12. PC中的电源按钮开关在关机后是否仍消耗电力？

需要明确的是，计算机已正确关机，而非处于“睡眠”模式。.

这两种状态之间存在差异。.

当计算机关机时，它不再从电源供应器获取任何电力。.

您会注意到显示器变黑，系统单元上的指示灯熄灭。.

但当计算机处于“睡眠”模式时，它会从电源供应器获取少量电力，并且您会注意到其指示灯仍在闪烁。.

如果您的计算机电源按钮开关带有LED，则它将保持亮起状态。.

因此，当计算机关机时，所有应用程序都已关闭，计算机完全断电。.

而将计算机置于“睡眠”模式仅是使其进入待机状态，如果您在键盘上输入任何内容或移动鼠标，它将再次唤醒。.

处于待机模式的笔记本电脑

13. 壁挂式PC上的电源按钮开关位于何处？

如果系统单元仍使用原装机箱壁挂安装，您可能会在其机箱前面板上找到电源按钮开关。.

而有些DIY用户移除了原装机箱，电源按钮开关位于主板上。.

其他人则重新布线电源按钮开关，并将其放置在开关盒或独立的PC电源按钮面板中，以获得更美观的外观。.

有些人更喜欢PC外部电源按钮或PC外部电源开关。.

壁挂式PC节省空间，并在您将其安装在墙上时营造出未来感。.

您还可以使用RGB PC电源按钮定制PC机箱电源开关，实现发光电源开关效果。.

主板上的电源按钮开关

14. 按下计算机上的电源按钮开关会发生什么？

当您按下计算机的电源按钮开关时，背后会发生一系列您看不到的过程。.

电源按钮开关是触发器，而主板负责实际的电源开关切换。.

当您按下电源按钮开关时，您触发了主板电路的状态改变。.

随后执行不同阶段：

• BIOS系统启动
• Stage 1 — boot loader (master boot record)
• Stage 2 – boot loader (LILO, GRUB, etc.)
• Kernel
• Initialize operation

All of these stages happen so fast, within seconds, until the operating system is loaded.

15. Why the power push button switch on the PC doesn’t work?

If your computer does not turn on even if you press the power push button switch, try to check the following:

• Is the power cable plugged in?
• Is the rocker switch in the back turned on?
• When you press the power push button switch, do you hear any sound or activity coming from the system unit?
• Is the chassis fan working?
• Did you notice any LED indicators that could have flashed for a brief moment?

If you answer yes to all of this, then the issue may lie on your motherboard.

If you answer no to the questions above, then your SMPS (switched-mode power supply) could be the problem and you may consider replacing it.

16. Did cars use the power push button switch?

是的，非常响亮。.

Some hybrid models are equipped with a power push button switch that turns their engine on and off.

It works like a power push button switch of a computer since it turns on a computer system to start the internal combustion engine and charge the hybrid battery or power the drive wheels.

Electric cars also needed to be turned “on” rather than starting up the internal combustion engine.

Modern vehicles with the integrated computer system have duplicated this idea with the development of the engine start and stop push button.

17. Do pipe organs have a power push button switch?

Yes, they did.

An old pipe organ has a power push button switch located on its console.

If it is turned off, there’s not electricity flow, and the pipe organ will not produce a single sound.

When the power push button switch is turned on, the electricity flows to the blower motor causing it to perform a rotary motion producing the wind pressure.

This wind pressure will is needed for the pipe organ to produce its sound.

However, modern pipe organs may have a key switch instead of the power push button switch for this function.

18. Does the power push button switch have a long working life?

This depends on how the power push button switch is made.

If it is poorly made, you can’t expect that it will last longer and it may even be faulty the moment you receive it.

But if it is a high quality power push button switch, you can be sure that it will last for many years.

The working life of the power push button switch is presented in two categories, its mechanical life cycle, and its electrical life cycle.

The mechanical life cycle refers to the power push button switch’s mechanical parts while the electrical life cycle refers to the electrical parts which are usually the contacts inside it and its terminals.

A power push button switch that is high quality can have around a million or more mechanical life cycles and about 200K plus electrical life cycles.

Despite this, several factors can affect the power push button switch’s life cycles.

It is best that you know what these factors are so you can prevent shortening the working life of the power push button switch or affect its working performance.

• Usage

Since the power push button switch will be used to switch machinery on or off, it will be subjected to frequent usage and sometimes abuse.

When it comes to this, you should choose an anti vandal power push button switch because this type of switch can endure repeated use.

• Environment setting

Sometimes the place where the power push button switch is located can also affect its working life cycle or its performance.

If the environment is where the power push button switch is going to be exposed to changing weather conditions, it is best to select the appropriate type of switch to protect itself from the harmful element.

You should consider choosing a water resistant power push button switch so that it is sealed to protect itself from the rain.

• Harsh temperatures

The materials making up the power push button switch may react to too high or too low temperatures.

Some parts can melt due to extremely high temperatures or in freezing temperatures; some parts may be stuck and become brittle until they break.

This is why you should know the manufacturer’s recommended temperature range which can be found in your power push button switch’s technical sheet.

• Frequent machinery movement

If the power push button switch is going to be used on machinery or equipment that frequently shakes, or vibrates, it can loosen the internal parts of the switch causing it to stop working.

Once again, you can choose the anti vandal power push button switch that is specifically built for this kind of condition.

• High current supplied to low voltage rating switches

There are different voltage ratings available for the power push button switch.

Make sure that the power supply will be appropriate for it, either a bit below its voltage rating or equal to.

Supplying a high current rating to the low voltage rated power push button switch can burn its contacts and damage them permanently.

You can find the voltage rating of the power push button switch on its product listing description, packaging information, or on the switch itself engraved on the bottom part of its body.

Example of technical data sheet for power push button switches

19. How to find a heavy-duty power push button switch?

If you are looking for a power push button switch that is heavy-duty, then you should look for one that has the IK10 seal.

It is the highest protection level a power push button switch can provide as protection against powerful impacts.

To obtain this seal, the manufacturer will submit their power push button switches to subsequent impact tests called the Charpy impact test and another required test which is the Drop weight impact test.

Each of them will test the durability and toughness of the power push button switch.

If the power push button switch passes a level, it will be given an appropriate IK rating.

The IK rating starts from 1 up to 10 and 10 is the highest rating.

因此，选择具有IK10防护等级密封的电源按钮开关，可确保其坚固耐用。.

IK10防护等级密封

20. 如何寻找防水电源按钮开关？

当您需要在游艇或船只控制装置上安装电源按钮开关时，建议使用防水或防溅型产品。.

判断电源按钮开关是否具备这些特性的方法是查看其是否具有IP65、IP67、IP68至IP69K的防护等级密封。.

该IP防护等级密封用于判定电源按钮开关及其他类型开关是否具备防固体和液体侵入的保护能力。.

为获得这些IP防护等级认证，制造商需将电源按钮开关进行多种防水测试，例如喷水、高压水枪喷射或浸没于水中。.

每个测试等级逐级加强，若电源按钮开关通过某一等级测试，即可获得相应的IP防护等级认证。.

最高等级为IP69K密封认证，这意味着电源按钮开关完全密封，可防止灰尘和水侵入，甚至能在3米深的水下浸没数分钟。.
