ABSTRACT:
A starter drive for an internal combustion engine in which the starter drive is mounted within the starter housing, and an ignition key activated solenoid for energizing the motor of the starter drive is contained in a solenoid housing that is attached to the starter housing and is integral therewith. The solenoid has a solenoid coil and an annular armature, and upon the energization of the solenoid coil by the connection of such solenoid coil to the battery through the ignition key, the annular armature, which is normally spring biased away from the solenoid coil, is magnetically attracted thereto. This movement of the annular armature establishes an electrical contact between a first terminal, which is connected to the battery, and a second contact which is connected to the starter motor. Release of the ignition key from the "start" position breaks the electrical contact between the solenoid coil and the battery, and the annular armature is then biased away from the solenoid coil by the spring, breaking the electrical contact between the battery and the starter motor.
