Push Button Switch Mom. Start

The Painless Wiring Push Button Switch Momentary (model 80503) is a 12-volt electrical control component rated for 20 amps of continuous current. This momentary-contact switch is designed for automotive and marine electrical systems where temporary activation of circuits is required—such as starter button engagement, auxiliary lighting control, or engine-mounted accessory operation. The switch maintains electrical contact only while depressed, automatically returning to the open position when released.

Rated at 20 amps at 12 volts, this push button switch handles moderate to heavy loads without degradation in switching reliability. The momentary contact design ensures the circuit closes only on demand, preventing accidental continuous activation and protecting connected components from unintended operation. The compact form factor (2.75 x 1.4 x 4.25 inches) allows flexible mounting in tight spaces common to engine bays, dashboards, and control panels. Weighing just 0.11 pounds, installation adds negligible weight to the vehicle while meeting the electrical demands of standard automotive and marine 12-volt systems.

This switch serves restoration projects, custom wiring harnesses, performance builds, and marine electrical upgrades where reliable momentary control is essential. Builders integrating Painless Wiring harnesses—known for comprehensive automotive electrical solutions—will find this component compatible with their system architecture. The 20-amp rating suits starter buttons, fuel pump priming circuits, horn activation, and dashboard-mounted auxiliary functions. Buyers requiring momentary push-button control for 12-volt systems will benefit from the Painless Wiring reputation for consistent, straightforward electrical components that integrate seamlessly into both stock and custom applications.
