Frequently Asked Questions

What is the difference between a switch and a relay in automotive use?

A switch is a manual device used to directly open or close a circuit (like turning on a light). 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 essential for protecting sensitive switches from high-amperage loads, such as headlights or air compressors.

Can I use a 12V switch on a 24V system?

No, you should not use a switch rated only for 12V on a 24V system. The higher voltage can cause arcing and premature failure of the switch contacts. Always ensure your switch is rated for the maximum voltage of your system (or higher).

What does 'SPST' mean on a switch?

SPST stands for Single Pole, Single Throw. It is the simplest type of switch, meaning it controls one circuit (Single Pole) and has only two positions: On or Off (Single Throw). It is the standard configuration for basic power control.

Are LED switches better than non-LED switches?

LED switches are not necessarily electrically 'better,' but the integrated LED provides a visual indication of whether the circuit is active, which is highly useful in automotive applications for confirming that accessories (like fog lights or winches) are running.
