Pushbutton switches, also known as control switches, are electric control switches mainly used to start and stop motors. They usually have one or several pushbuttons to control the on/off of electric circuits. A3SA-90A1-24SW is a specific type of pushbutton switch, whose applications and working principle are particularly worth a look.

Application Fields

First of all, A3SA-90A1-24SW are significantly used in automotive engines，which makes them ideally suited for a variety of cars and trucks. Equipped with a momentary mis- operating protection function, it offers safe and reliable operation.

Besides, it also fits light industrial equipment and commercial electrical appliance, fields as such like food processing, textiles, and chemical industries, etc. Thanks to its compact size, simply snap-in mounting assembly, the switch can be easily installed in most of these devices.

Working Principle

The switch is made mainly of a bracket, a spring, a micro-switch and a stopper. When the button is not pressed, the spring presses the stopper, which meanwhile presses the microswitch. As a result, the electric circuit is in the off state.

When pressing the button, the stopper is released, and the microswich is also released at the same time. The electric contacts on the microswich are connected, so the electric circuit comes into the on state. After releasing the button, the spring will recoil, the stopper will press the microswich again, and the electric circuit is back to the off state. In this basic cycle, the switch can be reset in off state, performing repeated operations.

In addition to this, A3SA-90A1-24SW is manufactured with double layers of terminal for protection, which not only guarantee the firm connection but also ensure the reliability of the switch. Along with its unique design for suppressing arcing, anti-dust and anti-moisture is achieved, guaranteeing its function in harsh environments.

Conclusion

To sum up, the A3SA-90A1-24SW pushbutton switch is a device mainly used to start and stop motors. It applies to automotive engines, light industrial equipment and commercial electrical appliance. When pressed and released, the electric contacts in the switch are connected and disconnected accordingly thanks to the cooperation of its components like bracket, spring, and microswitch. Furthermore, its double-layer terminal connection, arcing suppression, anti-dust and anti-moisture designs make it an ideal choice for the harsh working environments.
