Plunger Switches

Mechanical plunger switches signal many different situations that may occur in commercial vehicles, including power takeoff, idle and reverse gear, differential block, low gears brake failure, reduced gears, and handbrake failure. Our commercial automotive plunger switch portfolio has 5-volt DIN plunger switches and 12-volt-to-24-volt mechanical plunger switches that are available with different contact configurations (normally open or normally closed) and different electrical connections.
- Available with silver-plated and gold-plated contacts
- Options include normally open, normally closed, and normally open-normally closed contact configurations

What are plunger switches?
A plunger switch is a type of limit switch, which is an electromechanical device with an actuator that is mechanically linked to an electrical switch. Littelfuse automotive plunger switches are typically used to signal situations that may occur in commercial vehicles, such as power takeoff or handbrake status.
How do plunger switches work?
When the actuator on a plunger switch is pressed, it opens or closes an electrical circuit, effectively turning a connected device, such as a signal light or alarm, on or off.
