Push button switches<\/a>\u00a0are very common in life and production. This article introduces push button switches in detail to give you a comprehensive understanding of it. Whether you’re a newbie or an expert, you can learn more about them.<\/span><\/p>\n

What Is a Push Button Switch<\/span><\/h2>\n

There are many common switches in life, such as wall switches, tact switches, sensor switches, pressure switches, micro switches, toggle switches<\/a>, and push button switches.<\/span><\/p>\n

A push button switch is a relatively simple mechanical device used to control the activation or deactivation of various functions in machines and equipment. Push button switches are typically made of metal and plastic materials.\u00a0<\/span><\/p>\n

Push button switches are generally used on instruments or equipment to control equipment functions or control current. They are rarely used alone, so they are commonly found in cars, home appliances, and other equipment in daily life.\u00a0<\/span><\/p>\n

In industry, they are mostly used for functional operation and startup\/shutdown of machines. They are very important electrical components. Push button switches have many functions, and you can choose different types and functions according to actual needs.<\/span><\/p>\n

How Does a Push Button Switch Work<\/span><\/h2>\n

The push button switch achieves the purpose of turning on or off the instrument by pressing or touching the actuator of the button to allow current to pass or break. It is a relatively simple mechanical or electronic operating mechanism. It mainly implements this working principle through the following components:<\/span><\/p>\n

Shell and actuator:<\/strong> The shell of the push button is mainly made of a combination of metal and plastic and is primarily used for protection and insulation.<\/span><\/p>\n

Silver contacts:<\/strong> Generally made of silver-copper alloy, with a silver content reaching more than 85%. They need to be riveted<\/a> onto the brass parts with a rivet machine. When current passes through, they can better connect the circuit and have high conductivity. When the current is cut off, they can separate quickly.<\/span><\/p>\n

Spring mechanism:<\/strong> When the button is pressed, the spring prompts the contact to connect. In the self-returning state, the spring rebounds. In the self-locking state, the buckle locks the actuator head and the spring does not rebound.<\/span><\/p>\n

The push button switch mainly switches the current on or off through these components and will appear in the ON or OFF state.<\/span><\/p>\n

The Features of a Push Button Switch<\/span><\/h2>\n

The characteristics of push buttons are numerous, and here are a few common features:<\/span><\/p>\n

Simple operation<\/b><\/p>\n

Just press or touch the button to operate the switch. After pressing the button, it remains pressed and needs to be pressed again to change the state; this is a self-locking function. After pressing the button, the actuator springs back immediately without needing to be operated again. This is a momentary function. However, if it is an electronic type, the actuator will not show any change, but the pressure will be transmitted into the button interior to perform momentary or latching functions.<\/span><\/p>\n

High Safety Factor<\/b><\/p>\n

High safety factor: The metal button switch is made of metal, which is very strong and durable, with a high protection level and long service life. It does not require frequent replacement and maintenance, and it is available in different voltages and currents. Plastic push button switches are mainly composed of PBT, PA, and PC, offering higher insulation performance. Switches are generally tested and inspected repeatedly to ensure they can be reused and are safer.<\/span><\/p>\n

Diverse Functions<\/b><\/p>\n

The function selection of the switch is very diverse. In addition to latching and momentary options, there are also normally open, normally closed, SPST, SPDT, DPST, DPDT, and other functional options. You can even choose the light pattern and color for the LED function\u2026 Plus, it\u2019s waterproof and resistant to the elements.<\/span><\/p>\n

Strong aesthetics<\/b><\/p>\n

Whether it is a plastic or metal button switch, their different colors and materials give the switch different vitality and allow it to integrate perfectly with the instrument.<\/span><\/p>\n

In short, buttons have many advantages and are one of the indispensable electrical parts in life and production. If you are interested, please continue reading.<\/span><\/p>\n

What Types of Push Button Switches Are There<\/span><\/h2>\n

The application scenarios of push button switches are rich and the classifications are also very diverse. Classified by function, common ones include:<\/span><\/p>\n

By Function<\/span><\/h3>\n

\u81ea\u9501\u578b<\/a>: After pressing the switch button, the push button switch will remain in the pressed state, and the instrument will continue to operate. The actuator will not return to its original state until pressed again.<\/span><\/p>\n

\u77ac\u65f6\u578b<\/a>: Press the actuator of the push button switch and release your hand, the button will return to its original state.<\/span><\/p>\n

\"figure

Normally Open<\/a> (NO): Usually the «ON» sign is used to indicate normally open, which is a state of the contact, indicating that the contact is not connected when the contact is not energized.<\/span><\/p>\n

Normally Closed<\/a> (NC): Normally closed is usually represented by the «NC» mark, which means that the silver contacts are closed, the circuit is open, and the machine is running. If the button is pressed, the current is turned off and the circuit is disconnected. For example, the stop button of the escalator uses this function.<\/span><\/p>\n

SPST<\/a>: That is, single pole single throw, it only controls one circuit, connects two terminals, and has only two states: on or off. Switches with this feature are not durable and need to be replaced frequently, so they are more suitable for simple circuits, such as household light switches.<\/span><\/p>\n

SPDT<\/a>: That is, single pole double throw, which controls a circuit but connects three terminals, so it is suitable for selective control applications, such as switching between two circuits.<\/span><\/p>\n

DPST: That is, double pole single throw, with four terminals, can control two circuits at the same time but cannot switch, nor can it control one circuit alone. Suitable for applications where two circuits are switched off or on at the same time, such as the main power supply for household appliances.<\/span><\/p>\n

DPDT<\/a>: That is, double pole double throw, which has six terminals and controls two different circuits, including two input terminals and four output terminals, which are independent of each other. Compared with the other three functions, the DPDT switch is the most advanced kind.<\/span><\/p>\n

By Materials<\/span><\/h3>\n

Plastic materials<\/span><\/h4>\n

Classified according to materials, plastic push button switches include several materials. The main crust is PA and the base is PBT<\/a>. Nylon (Nylon, Polyamide, PA for short) refers to a plastic composed of polyamide resin and is resistant to high temperatures. PBT is a thermoplastic engineering polymer used as an insulator in the electrical and electronics industry. The base of the metal push button switch is made of PBT material for better insulation and flame retardancy.\u00a0<\/span><\/p>\n

Metal materials<\/span><\/h4>\n

Metal materials include stainless steel 304<\/a>, stainless steel<\/a> 316L, zinc alloy, nickel-plated brass<\/a>, and anodized aluminum<\/a>. These materials can be made into metal button switches. The use of metal as the appearance of the shell material, better protection and support of internal parts, play a better role in waterproof,<\/a> and dustproof, play the maximum role of the parts and extend the service life of the switch.\u00a0<\/span><\/p>\n

Mechanism types<\/span><\/h4>\n

The interior of the mechanical button switch is composed of springs, silver points, contacts, connecting rods, LED lights, waterproof rings and other materials, including ordinary push buttons and anti-vandal push button switch.<\/span><\/p>\n

Electronic types<\/span><\/h4>\n

Electronic switches include \u538b\u7535\u5f0f<\/a> type and \u7535\u5bb9\u5f00\u5173<\/a>, which are mainly composed of integrated circuit boards, wires, integrated shells, waterproof transparent rings and other materials.<\/span><\/p>\n
