Automotive Relays

Automotive relay switches can be found in just about every car, truck and even golf carts. A car relay switch is used to enable a low amperage circuit to switch on and off a higher amperage circuit like headlights, relays are also used to switch multiple things at the same time using one output. A single output connected to multiple relays allow opening and/or closing simultaneously. Most automotive electrical relays are SPST or SPDT.
