ABSTRACT:
An engine starter has a plunger electromagnetically actuated by holding and attracting coils to move a pinion toward a ring gear on the engine and also to move a first movable contact on the plunger towards first and second stationary contacts to be electrically connected together by the first movable contact to electrically energize a starter motor. A relay is provided and has normally open contacts electrically connected in series to a power source and the connection between the holding and attracting coils. The relay coil is connected in series to a starter switch and a temperature sensor. The temperature sensor is formed by a normally closed switch having a third stationary contact connected to the relay coil, and a bimetallic element carrying a second movable contact grounded through the bimetallic element. The temperature sensor is disposed to detect the temperature of one of the holding and attracting coils and arranged such that, when the temperature is raised to a predetermined level, the bimetallic element snaps to separate the second movable contact from the third stationary contact whereby the electrical supply to the holding and attracting coils is interrupted to interrupt the electrical supply to the starter motor. Thus, the starter will not burn up if the starter switch remains closed.
