This compact design push button, ON/OFF switch, can be mounted on most wood or plastic surfaces using two screws. The same screws can also be used to attach and secure the contact wires. One push turns the circuit on and the next push turns it off. This small switch is less than 18 mm long and less than 12-mm wide. The overall length including the contacts with mounting holes is 32 mm. It is designed for low voltage (1 to 24 volts) operation; however, it is strong enough to handle up to 250 volts/ 250 watts in a professional/ engineering design.
