Kind Code:
A
Abstract:
PURPOSE: To improve the contact reliability between contacts.
CONSTITUTION: A movable contact 8 of twin contact style is fixed to the electrode contact surface side of a movable iron piece 5 to form a closed loop for enclosing an iron core 3 in the state where the movable contact 8 and a fixed contact 10 make contact to each other, and since an induction current based on the magnetic flux of an electromagnetic coil 4 is carried in this cable run between the contact surfaces of movable contacts 9A, 9B to fixed contacts 11A, 11B, high contact reliability can be provided even in case of a minute load current.
