Abstract

PURPOSE:To make a high-reliable device which is suitable for high-speed operation by providing a returning spring at the opposite side of the suction surface of a fixed iron core in a device that a plunger fixed to a moving iron core freely slides and penetrates a fixed iron core from the suction surface of the fixed iron core. CONSTITUTION:A fixed iron core 1 having a suction surface 1a has a through hole 1b penetrated from the suction surface 1a and an engaging section 1c is provided at the opposite side of the suction surface 1a. A moving iron core 2 is arranged at the position facing to the suction surface 1a and a plunger 3 is fixed to the moving iron core 2 by a bolt 4. The plunger 3 freely slides and penetrates the through hole 1b of the fixed iron core 1 and an engaging section 3a is provided at the position facing to the engaging section 1c. A returning spring 7 is arranged between the engaging sections 1c, 3a. 6 is a latch operated by the movement of the plunger 3 and a breaker not shown in the drawing works by the operation of the latch.
