Abstract
A foot control installation, which is particularly adapted for use in a dental apparatus, in which an actuating member, operatively connected to a control and/or switching element, is supported in a housing of the dental apparatus, and is adapted to have movement imparted thereto, with one end of the actuating element projecting from the housing and having a foot contact. The foot control installation includes a foot-actuated pressure plate and downwardly depressable foot contact for actuating switches whereby, in addition to the control of the speed, other switching sequences are concurrently provided, for example, the predetermination of the rotational direction of the motor, the in-and-out switching of the motor, as well as the switching of a valve used for the supply of pressurized air or water to the handpiece of the drilling apparatus.
