How to wire a relay switch diagram. Diagrams will show how multiple relays one relay or another or just one relay can control your device. How to wire a relay switch diagram. If you do not install a relay and use a switch you could end up overheating the switch melting the wires and reducing the current that is getting to your lights making them less bright. This pinout image is only a 2 pole diagram for room on the page purposes but you can get the picture here with this one since a 3 pole will just have 1 more set of contacts. A set of wiring diagrams may be required by the electrical inspection authority to take up connection of the house to the public electrical supply system. The square relay pinout shows how the relay socket is configured for wiring.
The factory wiring in modern cars is light gauge and is not designed for additional loads. Nonetheless relays can control larger voltages and amperes by having an amplifying effect because a small voltage applied to a relays coil can result in a large voltage being switched by the contacts.
