An electrical switch ( ) comprises switch contacts ( ) having a closed condition and an open condition. The switch ( ) comprises an actuator ( ) movable in a first direction ( ) in a first stroke to close the contacts ( ) and movable in the first direction in a second stroke to cause the contacts to open. A rotatable bar ( ) is carried by the actuator ( ). The switch ( ) includes a mechanism ( ) for rotating the bar ( ) in response to movement of the actuator ( ) in the first direction ( ) in the first stroke, to locate the bar in a latching position to hold the contacts ( ) in the closed condition. The mechanism ( ) also rotates the bar ( ) in response to movement of the actuator ( ) in the first direction ( ) in the second stroke, to move the bar from the latching position and to cause the contacts ( ) to open.

Pushbutton switch

A switch ( ) comprises a printed circuit board ( ). The printed circuit board ( ) has a plurality of electrical contacts. The switch ( ) further comprises a carrier ( ) having an electrical conductor ( ) for connecting at least two of the plurality of electrical contacts. The carrier ( ) is movable relative to the printed circuit board ( ). The carrier ( ) further has a surface ( ) having a plurality of undulations ( ). The switch ( ) further comprises at least one flexible plastic cantilever portion ( ) of a plastic member housing the carrier. The cantilever portion contacts the plurality of undulations ( ). The undulations ( ) and the cantilever portion ( ) comprise a detent mechanism to restrain the carrier ( ) in a position to which the carrier ( ) is moved.
