Frequently Asked Questions

What is the difference between a switch and a relay?

A switch is a manual device used to directly open or close a circuit. A relay is an electromagnetic switch that uses a small current (from a switch) to control a much larger current in a separate circuit. Relays are used to protect switches and wiring from high-amperage loads, such as headlights or air compressors.

What does SPST mean on a switch?

SPST stands for Single Pole, Single Throw. This is the simplest type of switch, meaning it has one input and one output, and it simply turns the circuit On or Off. Most basic rocker and toggle switches are SPST.

Why would I need a battery disconnect switch?

Battery disconnect switches (like B0DQSZXPKT) are crucial for several reasons: preventing parasitic battery drain during long storage periods, acting as an anti-theft measure, and providing an essential safety cut-off in case of an electrical emergency or maintenance.
