This is done by manufacturers to reduce the amount of large, heavy wire in the run from the battery to a switch, and then from a switch to the high current using device.
They run a shorter heavy wire the shortest distance from the battery to the device, with a relay added in the circuit. They then run lighter control wire from the relay to a lighter/cheaper switch in the passenger compartment.
This serves two purposes:
- Saving of weight, reducing overall weight of the vehicle, and
- Reducing the amount of Copper wire, and thus material cost.

What the use of relay?
A; Its uses is to switch hi power loads with isolation
What is the difference between relay and ssr?
A relay is an electrically operated switch that uses an electromagnet to mechanically operate its contacts. An SSR (Solid State Relay) is a semiconductor device that uses electronic components to switch power on and off without any moving parts. SSRs are generally faster, quieter, and have longer lifespans compared to mechanical relays.
What are the uses of the relay?
They can be used as a kind of safety switch to allow a circuit with a small current through to switch on a circuit that will hve a larger current flowing through it.
Where is the 1984 Plymouth reliant oil relay switch?
Oil relay switch? No such switch on this vehicle.
Does a 1988 Chevy silverado 3500 have a fuel relay switch?
Relay, yes. Reset switch, no.Relay, yes. Reset switch, no.
What is a ignition relay?
The relay is a device that typically uses low amperage 12 vdc electrical (control voltage) to switch a much higher amperage circuit (load voltage). In the case of an ignition relay, the key/ignition switch is not capable of handling the high amperage requirements of the engine components electrical draw, so a relay is run in the circuit and controlled with the keyswitch. The relay has an electromagnet (control) and a switch (load) inside, and the electromagnet moves the switch when the control is energized. You do not ALWAYS have to have a burned fuse to have a bad relay, the contacts on the switch can burn, or the wire in the electromagnet can open, both resulting in a non-functioning relay.
How can you wire a switch to a relay?
To wire a switch to a relay, first connect one terminal of the switch to the positive power source. Then, connect the other terminal of the switch to the relay's coil terminal. Next, connect the other coil terminal of the relay to the ground. This setup allows the switch to control the relay, activating it when the switch is closed.
What is a split phase motor with relay and capacitor called?
A capacitor start motor is a split phase motor that uses a capacitor in series with the start winding to cause a greater phase shift, resulting in greater starting torque. It uses a centrifugal switch to switch out the start winding and capacitor once the motor is up to speed. I assume this switch is what you're referring to as a "relay".
Were is the Oldsmobile intrigue relay switch located?

Sj413 starter relay where is it?
If it is like my '86 Samurai there is no starter relay. It uses a starter solenoid on the top of the starter to pass battery to starter motor when the solenoid is activated via the key switch.
What does a fuel pump relay switch look like?
The fuel pump relay switch looks like the normal electric switch. The function of fuel pump relay switch is turn the fuel pump on.
What does the horn relay do in a 1963 Chevy 2?
A relay is a device that uses a small control current to switch a larger current. So the horn button (small current) turns on the relay which in turn energizes the horn (heavy current device).
