ABSTRACT:
An electromagnetic device for controlling the supply of current to an electric starter motor includes a pair of fixed contacts on a support for connection to a power supply and a starter motor, respectively. A movable contact which is adapted to engage both fixed contacts is carried by a movable core of an electromagnet so that upon energization of the electromagnet, the movable contact engages both fixed contacts to complete the circuit to the starter motor. A spring is provided for biassing the movable contact away from the fixed contacts upon de-energization of the electromagnet. A flexible braided conductor is permanently connected between the movable contact and one of the fixed contacts to provide an equipotential electrical connection therebetween.
