Patent ID: 7978037

Claim:
A switch device comprising: a fixed contact; a movable contact corresponding to the fixed contact; a movable contact spring on which the movable contact is provided and which is provided with an armature having a magnetic property; a sealed case accommodating the fixed contact, the movable contact, the armature, and the movable contact spring; yokes having a magnetic property and corresponding to the armature; a magnet for attracting the armature through the yokes by applying a magnetic force to the yokes; a moving element which is positioned on an outer side of the sealed case and is movably operated; and a magnetic shunt body which is moved by the moving element, wherein an attracting force of the magnet with respect to the armature through the yokes is changed by changing a distance between the magnetic shunt body and the yoke by movement of the magnetic shunt body, so as to move the movable contact together with the movable contact spring with respect to the fixed contact, and wherein the movable contact spring is provided with a bent portion which is bent in spaced-apart relation to the armature, the bent portion being provided between a fulcrum portion at a time when the movable contact spring moves with resect to the fixed contact and a portion where the armature is provided.
