ABSTRACT:
First and second switches are disposed in a housing which accommodates a magnetic switch of a starter motor. The magnetic switch is composed of a plunger and a exciting coil to drive the plunger. A movable contact of the first switch is mechanically connected to the plunger at such a space from a stationary contact of the first switch that it supplies driving current through a current limiting resistor when a pinion of the starter motor is brought in contact with a ring gear of an engine. A movable contact of the second switch is mechanically connected to to the plunger at such a space that it bypasses the current limiting resistor when the pinion is brought in mesh with the ring gear. A timer composed of a bimetal switch is provided to interrupt the driving current through the current limiting resistor if the resistor is heated at a designated temperature.
