Magnet switch for starters
First Claim
1. A magnet switch for a starter for supplying an electric current from a battery to a starter motor, the magnet switch comprising:
- a main stationary contact connectable to the battery;
a heat generating member electrically connected to the main stationary contact for generating heat when the current is supplied thereto; and
an auxiliary stationary contact electrically connected to the main stationary contact through the heat generating member,wherein the main stationary contact and the auxiliary stationary contact are adapted to be brought into a conducting state to control current supply to the starter motor.

Abstract
In a starter, when a magnet switch is operated for starter operation, an auxiliary movable contact connected to a main movable contact by a holding member comes into contact with an auxiliary stationary contact to supply an electric current from a battery through resistors, auxiliary stationary contact and auxiliary movable contact to apply a low voltage to a motor for low speed rotation. Subsequently, as a plunger of the magnet switch moves further, the main movable contact comes into electrical contact with a main stationary contact, so that the resistors are short-circuited and the electric current from the battery flows to the motor without flowing through the resistors to drive the motor for high speed rotation.
