ABSTRACT:
A chin activated switch for use in adjusting the movement of a binocular microscope along three orthogonal axes allows the operator to utilize his hands and feet to control other devices. This chin switch contains a plurality of microswitches which are activated by specific movements of the chin. A chin plate upon which the operator's chin rests is connected to a pivot rod and rocker assembly the movement of which actuates the microswitches. These microswitches in turn control motors which move the microscope in the desired directions.
