Pushbutton switches are a type of electrical switch that are actuated by a short, manual push of a button. The A22-TW-02A is a pushbutton switch that is designed to perform multiple functions in one switch. This article will focus on the application field and working principle of this device.

Application

This switch is well suited for applications in which space is limited and multiple functions are required. It is ideal for small control panels, display lighting, security systems, audio/video equipment, and HVAC systems.

The A22-TW-02A is a versatile switch that can integrate two, three or four contact positions. It can be used for momentary or latching bias (NO/NC). This switch also has a robust, snap action, tactile actuator.

In addition to its versatile design, the A22-TW-02A offers a long life expectancy of up to one million operations. It has a high sensitivity of 0.2 N and a working temperature range of -30 to +85 °C.

Working Principle

The working principle of the A22-TW-02A is based on an electrical contact closure. When a button is pressed, the internal switch arm is activated and makes contact with a contact point, closing the electrical circuit.

The switch is also designed to have an adjustable contact force, which means that the pressure needed to activate the switch can be adjusted by simply turning the knob located at the base of the switch.

The A22-TW-02A also features an integrated LED light, which illuminates when the switch is activated. This LED can be used to indicate when a switch is in the “on” position or when a button is pressed.

Conclusion

The A22-TW-02A is a versatile, space-saving pushbutton switch that is ideal for applications that require multiple functions and a long life expectancy. Its adjustable contact force and integrated LED light make it a great choice for any application. We hope that this article has given you a better understanding of the application field and working principle of this device.
