Abstract

A microswitch produced from a predominantly plate-shaped substrate can include: a stationary contact piece (7, 9) on the substrate, a moveable contact piece (6), which electrical contacts the stationary contact piece (7, 9) 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 (1) which holds the moveable contact piece (6) and is fixed to the substrate by two ends (2, 3), and a drive (10) which guides the contact carrier (1) into the switch-on or switch-off position by elastic deformation. The contact carrier (1) can deform in substrate-parallel fashion. In a stable position corresponding to the switch-off position, the contact carrier (1) has the form of a symmetrical antinode. In a stable position corresponding to the switch-on position, the contact carrier (1) is deformed in the manner of an asymmetrical antinode.
