from flyback voltage and it can be used in both ac and dc circuits see the note about switch contact ratings the following diagrams show some mon relay wiring schemes that use 4 pin iso mini relays 1 adding driving lights that e on with the headlight main beam this simple circuit uses the power feed to the headlight main beam bulb as the trigger to energise a relay the high current circuit in this relay feeds power to the driving light bulb this relay is about as simple as it gets the two pins in the bottom left of the pin diagram are the coil that s what the curly looking symbol means if you apply 5 v accross those pins the switch part of the relay will go one way when the 5 v is disconnected from the coil a spring in the relay causes it to switch back to the other state p div div div class b fcv2 table tbody tr data exp h data exp noani 1 td style a href https electronics stackexchange.
