Starter Relay: Description and Operation
The starter motor solenoid relay switch is an electrically operated switch used to connect the windings in the starter motor solenoid to the battery. The
relay consists of a coil, plunger and contact disc. When the coil is connected to battery power through the ignition switch, it becomes an electromagnet.
The magnetic force draws the plunger into the coil core. A disc connected to the plunger contacts the relay terminal, completing the battery to solenoid
circuit. When the key or button is released, the magnetic field in the coil collapses and spring pressure returns the plunger and contact disc to the open
circuit position.
NOTE: Appearance of Starter Relay differs from actual relay. Functionally relays are the same.
