A pushbutton switch with an actuating bar which has movable switch contacts connected thereto so as to be movable therewith, and is axially movable in a switch housing against the thrust of a return spring. The actuating bar has associated therewith a locking device including a connecting link guide and a guiding pin. When the actuating bar is moved from its starting or rest position into a first switch position, the locking device holds the actuating bar in this first switch position, and when the actuating bar is subsequently actuated, the locking device releases the actuating bar from the first switch position. As a result thereof, the return spring returns the actuating bar to its starting or rest position. The switch also includes stationary switch contacts arranged on the switch housing and operable to be electrically conductively engaged by the movable switch contacts when the actuating bar is in its first switch position. The stationary and movable switch contacts surround the locking device which is located in a longitudinal central plane of the pushbutton switch.
