RELAY SWITCH CIRCUIT
A relay switch is an electrically operated switch that is used in applications that require the control of a circuit by a low-power signal, where the control and controlled circuits must be electrically isolated from one another.
AUTO RELAY
Relay circuit switches are found in most vehicles driving on the nation's roads. They are most commonly used to enable a low amperage circuit switch On or Off a higher amperage circuit. The best example of this is probably the switching on of the vehicle's head lights. Browse our bargain car relay range today - and you will not be disappointed.
RELAY CIRCUIT APPLICATIONS
Relay switches should be used in situations when a heavy current is being switched. for example - a heated wind screen, car horn or a starter solenoid. A Relay should be included in this event to protect the switch and the cable.
Relays allow a greater current load to be controlled by a lighter current switch at the facia. They serve to reduce voltage drops where long connections/ cabling are involved.

CHANGEOVER RELAYS - HOW THEY WORK
Automotive relays are located in the majority of modern vehicles on the road today. For the most part they are employed to allow a low amperage circuit switch on or off a higher amperage circuit. One of the most common applications for an automotive Relay Switch Circuit is found in the mechanism used to turn on and off the headlights of a vehicle.
CIRCUIT PROTECTION
If the headlights were directly wired to the headlight switch the amp rating of the switch would be exceeded and there would be significant risk of causing irreparable damage such to the circuit. An example of such damage to look out for are: melted wires and/ or electrical fire.
A relay switch circuit is a safer circuit. Auto relays can also be employed to facilitate the switching of multiple components at the same time using one single output.
We also stock a great range of automotive cable, a line of bargain battery terminals and a great selection of silicone tubing & hosing. All your automotive relay switch needs in one place.
