An electromagnetic switch for use in actuating a starter for automotive vehicles is provided. The switch includes fixed contacts, a moving contact, and a plunger shaft. The moving contact is joined to a plunger shaft through an insulator. The plunger shaft is to be moved magnetically to bring the moving contact into abutment with the fixed contact to establish electric communication between the fixed contact.
