A push switch, comprising:
- a housing including a first accommodating portion;
- a central fixed contact provided at a bottom of the first accommodating portion;
- a movable contact member arranged in the first accommodating portion and configured to contact the central fixed contact with a center portion of the movable contact member by inverting the movable contact member upon receiving a pressing force from above;
- and
- a cover member configured to cover an upper portion of the first accommodating portion, wherein
- the movable contact member is formed of a plurality of metal plates stacked on top of each other,
- a lowermost metal plate arranged at a lowermost position of the plurality of metal plates includes a rotation stopper provided projecting outward from an outer peripheral edge of the lowermost metal plate,
- the housing includes a second housing portion for accommodating the rotation stopper, and the rotation stopper contacts an inner wall surface of the second housing portion to suppress rotation of the lowermost metal plate,
- an uppermost metal plate arranged on an uppermost side among the plurality of metal plates does not include the rotation stopper,
- a pressing member configured to suppress rotation of the uppermost metal plate by pressing a surface of the uppermost metal plate from above is provided between the cover member and the uppermost metal plate, and
