Introduction

Pushbutton Switches are widely used in various application fields and can be divided into two types: momentary and maintained. Momentary switches are usually actuated momentarily and then released; maintained switches remain in the "on" position or in the "off" position until depressed again. Pushbutton switches are mainly composed of contacts, actuators, terminals, and mounting hardware. It’s working principle is that, when the actuator is pressed, the contacts make contact and electronically close the circuit, sending electrical signals in the desired direction.

Application Field

Pushbutton Switches have a wide range of application fields, they can be used as contact elements in sensors to monitor field conditions such as temperature and pressure, and can be used to control mechanical devices such as motors and pumps. Pushbutton Switches are also widely used for the realization of control functions in the home, the control of production machinery of machinery and equipment, the realization of function control of electronic information, the workpiece control of electronic and electrical equipment, etc.

Working Principle

The working principle of Pushbutton Switches is quite simple, it relies on the contact’s motion. When the actuator is pressed down, the contacts close and make a connection thereby switching on the circuit. The contact\'s motion can be blocked by the side or back of the actuator; this prevents any further motion after the switch is actuated, ensuring that the circuit is maintained. Depending on the type of the Pushbutton Switches, the contacts either open the circuit (e.g. when the switch is released) or are maintained in their closed state increasing the circuit’s carrying current.

Conclusion

Pushbutton Switches are simple, reliable, and highly versatile devices capable of performing a variety of functions in a wide range of application fields. By pressing the actuator, the contacts make contact and close the circuit, allowing electrical signals to travel in the desired direction. Pushbutton Switches are durable and cost-effective, making them an excellent choice for creating both simple and complex circuits.
