A micro switch plunger is a type of switch actuator that uses a plunger to make electrical contact. The plunger is typically a small, cylindrical piece of metal that is spring-loaded. When the plunger is pressed, it makes contact with two electrical terminals, closing the circuit. When the plunger is released, the spring pushes the plunger back, breaking the circuit.
Micro switch plungers are used in a wide variety of applications, including:
- Appliances: Micro switch plungers are used in appliances such as refrigerators, washing machines, and dryers to detect the position of doors and other moving parts.
- Automotive: Micro switch plungers are used in automotive applications such as brake lights, turn signals, and seatbelt sensors.
- Industrial: Micro switch plungers are used in industrial applications such as machine safety systems, assembly line automation, and process control.
