ABSTRACT:
A foot regulator which is especially suitable for use in connection with dental treatment equipment consists of a bottom, a control member which is cylindrical and which can be displaced in the horizontal plane and be turned, a housing with a printed circuit supporting a switch, and an upper part. The control member has a recess which in its center position is located immediately under a central hole in the housing, the control pin of the switch extending down into the hole. In the recess there is placed a ball which by the horizontal displacement of the control member will activate the switch, the ball being pressed up into the hole. Turning of the control member is detected by way of optical sensors. By the use of this foot regulator easy and simple operation is obtained in that it can be controlled in the same manner from all sides so that fatiguing working positions for the user can be avoided.
