Abstract
A movable contact which is positioned inside a sealing case is moved by a magnetic shunt body which moves outside the sealing case. The movement of the movable contact by the movement of the magnetic shunt body is caused by a change of magnetic force of a magnet through a pair of yokes. The magnetic shunt body is assembled to a moving member, and elastically moves around the moving member resisting a first spring.
