Abstract:
1. An electromagnetic switch for a starter, comprising: a main contact provided on a motor circuit for the starter and configured to interrupt energization current to a motor; and a solenoid configured to open and close the main contact in response to ON/OFF operation of an electromagnet, the solenoid comprising: wherein the main contact comprises: a cylindrical slidable member that is separate from the plunger, loosely encompasses an outer circumferential periphery of the plunger rod, and is axially movable integrally with the plunger, the slidable member being at least partially axially inserted into the inner circumferential periphery of the cylindrical bore whether the solenoid is in its active or inactive state, and an outer circumferential periphery of the slidable member being entirely circumferentially in sliding contact with the inner circumferential periphery of the cylindrical bore; and a contact pressure spring disposed on an outer circumferential periphery of the plunger rod, the contact pressure spring being configured to urge the movable contact against the pair of fixed contacts to be in contact therewith when the main contact is closed, wherein:
