Turn Signal Switch Wiring Diagram

A turn signal switch is a component of a vehicle's electrical system that controls the operation of the turn signals. It is typically located on the steering column and is operated by a lever or stalk. When the lever is moved, it sends a signal to the turn signal indicator lights on the dashboard and to the turn signal relay. The relay then activates the turn signal flasher, which causes the turn signals to blink. The turn signal switch wiring diagram is a schematic representation of the electrical connections between the turn signal switch and the other components of the turn signal system. It shows the location of the switch, the wires that connect it to the other components, and the function of each wire. The following is a turn signal switch wiring diagram for a typical vehicle:
