TECH NOTES:
A relay is an electrically operated switch that opens and closes under the control of another switch or electrical circuit.
Relays are used where it is necessary to control a high-power circuit with a low-power signal (with complete electrical isolation between control and controlled circuits), or where several circuits must be controlled by one signal.
In the case of a rear window defroster relay/timer, the defroster is activated or deactivated through this relay when the rear window defroster switch is pressed. It will also automatically deactivate when the relay's programmed timing cycle ends or the ignition switch is turned to the off position.
