ABSTRACT:
The invention concerns a rotary selector as control device for switching on and off and automatic control of a number of different program steps of electrical appliances such as washing machines, tumble dryers, dishwashers and the like. The rotary selector in the invention functions as a control device for switching on and off and automatic control of a number of different program steps of electrical appliances such as washing machines, tumble dryers, dishwashers and the like. This is done by connecting a pivoted actuator (3) via an operating shaft (4) with a magnetic rotary field sensor (5) in Hall sensor technology. An interface is integrated into the rotary field sensor (5), via which an angle-dependent code is transmitted to an electronic evaluation and control unit. In addition there is a device for positioning the actuator (3) at a precise angle, whereby a particular program cycle is assigned to each setting of the rotary field sensor (5) and each switch position of the actuator (3).
