This electromagnetic (solenoid) push-pull switch works on 12V with a current of up to 1A. This solenoid contains a pin which is retracted about 10 mm when voltage is applied. When the voltage is removed from the solenoid, this pin will jump back. At the back of the pin there is a thread with a removable bolt, so that the pin cannot fall out of the solenoid when there is no voltage on it. The dimensions of the housing (without pin) are 30 x 15 x 14 mm.
Note: The pin of the solenoid cannot move when pressure is applied to it.
