Abstract
A push-button switch may include a housing, an operation unit, a lock lever unit, a transmission mechanism, a movement regulating portion, a contact mechanism, and a first biasing portion. The movement regulating portion enables movement of a lever body to a second position when an end of the operation unit on a housing portion side is positioned at an initial position, and disables movement of the lever body to the second position when the end of the operation unit on the housing portion side is positioned closer to an operation surface than the initial position in a movable direction. The first biasing portion biases the plunger from an operating position toward a return position.
