PURPOSE:To reduce the number of parts and to eliminate contact between the spring and the contact and the shortcircuit between the contact and the earth by placing a spring for returning the movable contact and the plunger to the opposite direction from the fixed contact between a fixed boss and a spring receiver. CONSTITUTION:A magnetic switch 2 is provided with fixed contacts 13, 14, a movable contact 15, a contact shaft 16, a plunger 17, a returning spring 18, and a contact push spring 19. A spring 18 for returning the movable contact 15 and the plunger 17 in the opposite direction from the fixed contact is placed between the fixed bass 24 and a spring receiver 25 secured to one shaft end of the contact shaft 16. Since the returning function of the contact shaft 16 and the plunger 17 is achieved through single spring, the number of parts can be reduced. |
