Different applications of the push button on/off

5. What exactly happens when you press the push button on/off?

To understand this better, you need to know the parts of the push button on/off first.

The push button on/off has two main parts which are the head and the body.

The head has the actuator or the button that you press to actuate the switch.

While the body houses the push button on/off interior components.

These components are the spring, static and movable contacts.

The contacts are the conductive components of the push button on/off.

The movable contacts are positioned under the actuator, and then the static ones are fixed on the terminals.

When you press the actuator of the push button on/off, the spring inside it contracts and the contacts touch each other.

This position permits the flow of current and actuates the switch.

And when you release the actuator, the spring expands, the contacts separate, and the current flow stops.

What is described here is just one example of what happens when you press the push button on/off.

It is because there are contact states and switch actions that affect how it works which are also necessary to learn to help you find the precise switch for your application.

Push button on/off operation

6. What are the different contact positions of the push button on/off?

The push button on/off has two main contact positions when it is not actuated.

These contact positions change when you press the actuator to actuate the switch.

This is also true with the other types of switches.

Below are the two contact positions and a brief description of each:

• The normally open push button on/off

In this contact position, the contacts are open or they sit separately away from each other and the current is not flowing.

But if you press the actuator, the contacts make contact with each other permitting the current to flow.

This contact position is also called the push to make, push to close switch, or NO push button.

• The normally closed push button on/off

In here, the contacts are originally connected and the current is freely flowing.

By pressing the actuator, the contacts separate, and the current stops flowing.

This is also called the push to break, push to open switch, or NC push button.

The normally open push button on/off and normally closed push button on/off contact states are denoted by different symbols in an electrical circuit.

Depending on the type of circuit diagram, these contact states can be represented by their general or schematic symbols.

These symbols are also essential to know so you can identify which contact position of a push button on/off you need to purchase.

7. What is the push button on/off switch actions and why are they important?

The push button on/off has two types of switch actions which are the momentary push button on/off and the latching push button on/off.

These switch actions are also available in other types of switches.

You need to know the difference between the two otherwise you may end up purchasing the push button on/off with the wrong switch action.

Here are the switch actions and what they are:

• Momentary push button on/off

In this type of switch action, the actuator does not stay compressed after pressing it rather it will spring back to its original position.

It is also known as momentary on/off push button.

Examples of this are doorbells, vehicle horns, vending machine buttons, dispensers, and parking ticket buttons.

• Latching push button on/off

这也被称为保持型开关动作或自锁开关，因为当您按下执行器时，它会保持压缩状态，直到您再次按下才会释放。.

此类开关的示例包括电梯呼叫按钮、电灯开关、音响设备上的控制开关等等。.

您必须了解您的应用需要哪种类型的开关动作。.

例如，如果在需要自锁开关动作的应用中使用瞬时按钮开关，您可能会遇到困难，并且它可能完全无法正常工作。.

这也可能导致使用按钮开关时产生混淆、工厂生产延迟、浪费宝贵资金等等。.

瞬时按钮开关应用示例

8. 按钮开关在电路中有配置方式吗？

按钮开关在电路中有两种配置类型。.

可以是SPST（单刀单掷）和SPDT（单刀双掷）。.

极数表示开关可以控制的电路数量，对于按钮开关，两种配置都是单极。.

掷数表示执行器可以处于的位置数量，在这种情况下，按钮开关有两个执行器位置，即“开”和“关”位置。.

SPST按钮开关有一个输入和一个输出，而SPDT按钮开关有一个输入和两个输出，可以根据接线方式互换。.

在电路中，您会发现它们有独特的符号来表示其极数和掷数。.

这将使您能够轻松确定按钮开关应用所需的配置类型。.

SPDT和SPST常开常闭符号

9. 如何连接带LED的按钮开关？

通常，当您订购按钮开关时，您也会收到其接线说明。.

但如果您没有收到，这里有一个关于如何连接按钮开关的简单指南。.

如果您希望无论按钮开关是否被触发，LED都保持常亮：

1. 取一根导线，将常开端子连接到正极端子。.
2. 然后从正极端子连接另一根导线到设备。.
3. 将另一根不同的导线连接到公共端或“C”端子，然后连接到电源。.
4. 对于接地，将一根导线连接到负极端子。.

如果您希望仅在按下按钮开关的执行器时LED才亮起，可以按以下方式操作：

1. 取一根导线，将其从常开端子连接到正极端子。.
2. 然后取另一根导线，将其从正极端子连接到电源。.
3. 然后将另一根不同的导线连接到公共端子。.
4. 最后，将另一根导线连接到负极端子用于接地。.

这两个说明都很简单且相似，因为两者之间的唯一区别在于您将正极端子的导线连接到何处，是连接到设备还是电源。.

除了此说明外，您还可以向他们索取您购买的按钮开关的接线说明副本，或重新访问产品列表页面，因为接线指南也可能发布在那里。.

因此，您冒着水进入按钮开关的风险，这可能导致其内部组件快速腐蚀，或者更糟的是，危及接地开关的安全性。.

在这种情况下，您应使用防水按钮开关，其密封设计可防止水进入，确保长使用寿命和安全使用。.

其他类型的环境包括潮湿、含盐、湿润，或者温度极端（过冷或过热）。.

对于每种类型的环境，都有专门制造的、能够耐受该环境的合适按钮开关。.

• 设备振动

振动、抖动或脉动等运动可能使按钮开关的组件松动，并可能导致其功能失效。.

在这种情况下，如果不可避免，最好考虑使用能够处理此类应用的防破坏按钮开关。.

• 额定电流

按钮开关有特定的额定电流，您可以通过查看其产品描述或开关本身的标签轻松识别。.

通常建议电源的电流小于或等于按钮开关的额定电流，而不是提供更高的电流。.

向按钮开关提供高于其承受能力的电流可能会烧毁其触点，并最终导致其停止工作。.

可能还有其他影响按钮开关质量和性能的因素未包含在此列表中。.

然而，此列表已经让您对哪种按钮开关适合您的应用以及其安装环境类型有了一些了解。.

14. 为何门铃使用启停按钮比拨动开关更理想？

门铃优先选用启停按钮而非拨动开关，原因有多方面。.

具体而言，瞬时式启停按钮是理想选择。.

这是因为当访客按下瞬时式启停按钮时，电流会施加到门铃的响铃装置上。.

当访客停止按压启停按钮时，电流停止流动。.

在电流施加期间，电磁铁通电使击锤移动并敲击铃铛。.

电流停止流动时电磁铁断电，击锤在弹簧或重力辅助下返回静止状态。.

人们不希望长时间按住门铃按钮，通常会立即松开。.

一旦松开启停按钮，电流中断，从而避免门铃电磁装置浪费更多能量。.

但如果持续施加能量，门铃组件可能发热并损坏。.

若门铃设计采用拨动开关而非启停按钮，则无法依赖访客关闭电流。.

门铃会发热，从而导致损坏并缩短其使用寿命。.

门铃应用启停按钮

20. How do correctly store push button on off to avoid damaging them?

Storing the push button on off correctly can prevent instances that can damage them and also help prolong their shelf life.

Whether you have ordered a batch of a push button on off or just a few of them, you still need to properly store the ones you will not be using yet.

In this way, you can be sure that the push button on off will still be in its optimum performance the next time you need it.

• Follow the manufacturer’s recommendations for storing the push button on off

Sometimes manufacturers include some documents along with your push button on off order that details how you should store the switches.

However, if it is not provided, you can visit the manufacturer’s website and check the information yourself.

You can also consult your manufacturer directly to receive the instructions from them.

Another way is to read the technical specification sheet available that will provide you with the specifications of the push button on off where you can gain some understanding of what to do when it comes to storing them.

• Keep the push button on off in a safe container

As much as possible, avoid placing the push button on off inside a container along with other objects.

Some of these objects may be too sharp or can contain substances that can damage the switches.

If you have ordered a batch of push button on off, it may come in a box where each of them is arranged in a molded tray container.

You can just simply get how many push button on off you need for your application and leave the rest inside the box.

• Avoid placing heavy objects above it

Heavy objects can cause damage to your switches’ box or any fragile container when they are placed on top.

Put your push button on off in a separate space or spot where it will be safe.

• Inspect them occasionally

Inspect the push button on off once in a while.

Clean them with a dry clean cloth and check if there are any signs of corrosion.

When this happens, the place where it was stored may be too damp which may not be good for the type of switch you have.

• Find a dry and cool place to store the push button on off

If you have shelves or cabinets where you can store the push button on off then that’s good.

But if you have a storage room, perhaps it’s much better.

As long as these places are dry and at least with ambient temperatures to help prolong the shelf life of your push button on off.

• Overexposure to sunlight is bad

Direct sunlight can cause rapid discoloration of the push button on off or even deterioration of its components damaging it permanently.

This happens especially when the push button on off switch is made from plastic which becomes brittle and pale in color when overly exposed to direct sunlight.
