The control device of automobile starter includes electromagnetic switch, starting relay and ignition starter switch lamp parts, in which the electromagnetic is made together with the starter.

Electromagnetic Switch Working principle

When the suction coil and the flux direction of the coil are kept, the electromagnetic force is superimposed, which can attract the active iron core to move forward until the contact of the push rod front will connect the electric switch contact to the main circuit of the potential motor. When the suction coil and the magnetic flux direction produced by the coil are reversed, the electromagnetic suction mutually cancels, and the movable core can be reset automatically, the contact disc and the contact point are disconnected and the main circuit of the motor is disconnected under the action of the reset spring.
