Abstract
A microswitch produced from a predominantly plate-shaped substrate can include: a stationary contact piece ( ) on the substrate, a moveable contact piece ( ), which electrical contacts the stationary contact piece ( ) in the switch-on position of the switch and is electrically isolated from the stationary contact piece in the switch-off position of the switch, a bendable contact carrier ( ) which holds the moveable contact piece ( ) and is fixed to the substrate by two ends ( ), and a drive ( ) which guides the contact carrier ( ) into the switch-on or switch-off position by elastic deformation. The contact carrier ( ) can deform in substrate-parallel fashion. In a stable position corresponding to the switch-off position, the contact carrier ( ) has the form of a symmetrical antinode. In a stable position corresponding to the switch-on position, the contact carrier ( ) is deformed in the manner of an asymmetrical antinode.
