Abstract
The foot switch controls the drive to a dentist's drill having a footplate actuating the switch when depressed against spring action, together with an adjusting member, also foot controlled. There is an opening (9) in the footplate (2) through which protrudes a cylindrical roller (10), coupled to the adjusting member (12). The roller spindle (11) is parallel to the plane of the opening and to the front edge (6) of the footplate. The roller can be arranged to run in bearings on the underside of the footplate, and the member can be a rotary potentiometer, of which the roller spindle forms the axis.
