Micro Relay is a 20 amp, 4-pin switching relay used within the vehicle electrical system to control a high-current circuit from a low-current signal.

The four-pin layout provides a single normally-open (make) contact set: two terminals feed the control coil, and the remaining pair carry the switched load. Energising the coil closes the contacts, allowing a low-current output to operate a higher-current device such as a lamp, motor or pump. The black housing carries a yellow identification band denoting its current rating.

Its compact micro footprint matches the relay sockets used in modern fuseboxes and relay carriers.

Frequently asked questions

What does the 20A 4-pin micro relay do?
The 20A 4-pin micro relay switches a higher-current circuit from a low-current signal. The four-pin layout gives a single normally-open contact set: two terminals feed the control coil and two carry the switched load. Energising the coil closes the contacts to power a lamp, motor or pump.
What's the difference between a 4-pin and a 5-pin relay?
A 4-pin relay like this one has a single normally-open make contact, so it only switches a circuit on or off. A 5-pin relay adds a changeover contact with a normally-closed output as well. Use the 4-pin where the circuit only needs simple on/off switching.
How do I identify and fit this micro relay?
This micro relay is black with a yellow identification band marking its 20A rating, and its compact footprint matches the micro relay sockets used in modern Land Rover fuseboxes and relay carriers. Check your socket is the micro size before ordering, then plug it straight in.
Which Land Rovers use this micro relay?
This micro relay suits later Land Rovers with micro relay sockets, including the Discovery 3, 4 and 5, Discovery Sport, Range Rover L322 and L405, Range Rover Sport, Evoque and Velar. Confirm the relay you're replacing is a 20A 4-pin micro type before ordering.
