Abstract
A push switch includes a stationary contact and a movable contact. The stationary contact includes a base material and a conductive layer that covers the base material. The movable contact is disposed opposite a contact surface of the stationary contact. The movable contact is movable between a first position where the movable contact is in contact with the contact surface and a second position where the movable contact is apart from the contact surface. The stationary contact has a groove that divides the contact surface into a plurality of areas. Connection surfaces connect respective opening edges of the groove with a bottom of the groove. Each of the connection surfaces has a slope that is inclined at acute angle relative to the contact surface.
