Changeover Relay Switch - How it works
Automotive relays are found in pretty much every vehicle on the road today.
Most often they are used to enable a low amperage circuit unit to switch on and off a higher amperage circuit.
For example - a common application seems them used to turn on the headlights. Shop our range of 5 pin automotive relays, relay 12v 40a 5 pin, 5 pin 12v relay, and 5 pin relay 12v today. We have the best value on 5 pin relays, 5 amp relay, 12v relay 5 pin, and 12v 5 pin relay online in the UK. Shop 5 pin relays and relay 5 pin 12v today.
If you hooked up the headlights directly to the headlight switch you would exceed the amperage rating of the switch and risk causing significant damage such as; melting wires and risking starting an electrical fire.
Relay Circuits - Multiple Switching
Relays are also used to facilitate the switching of multiple components at the same time using a single output. A single output connected to multiple relays will allow you to open continuity and/or close continuity simultaneously. Shop 12v 40a relay 5 pin replays now.
