Abstract
Two protrusions are disposed on the fixed contact along a lateral direction on a contacting surface. The two protrusions are disposed in a longitudinal direction with a predetermined interval on the contacting surface, and a planar portion is formed between the two protrusions. A single projection that intersects perpendicular to the two protrusions disposed on a first fixed contact and another single projection that intersects perpendicular to the two protrusions disposed on a second fixed contact are disposed on a movable contact. Thereby, when the movable contact contacts to a pair of fixed contacts, since the protrusions disposed on the fixed contact and the projections disposed on the movable contact contacts only at intersections of each other, a contacting surface pressure is increased and a crushing force for ice frozen on a surface of the fixed contact becomes large.
