Abstract: A foot switch for use in the control of medical apparatus comprises a pedal that is connected to and movably seated on a floor plate of a joint connection, a sensor linked to a switch element, and a repositioning device disposed between the floor plate and the pedal. The repositioning device ensures that an operating force must be applied to the upper surface of the pedal to produce a tilting movement of the pedal out of an initial position into an operating position in which a smaller angle is defined between the floor plate and the pedal than in the initial position and in which the sensor is activated to trigger the output of a switch pulse from the switch element. The improvement of the present invention consists of the combination of the repositioning device and the joint into an elastic joint device. The simplified foot switch is easily disinfected.
