Push button switches for use in 12 volt electrical systems. Our push button switches are single pole single throw switches that are normally off, and turn on when pushed. These switches have two contacts or connections, and are commonly used for the momentary activation of a circuit such as a horn, relay, or starter. For high current applications such as starters, we feature a heavy duty 50 amp push button switch with that comes with a boot to make it waterproof. Connections to these switches are usually done via screw terminals, and the switches are mounted using a drilled out hole.
