Abstract
The rotary electrical switch 1 which is mounted on a circuit plate 7 furnished with a printed circuit comprises a switch wheel 4 which is rotatably supported on the circuit plate 7 and whereat a contact bridge 48 is inserted into a pocket 46. On rotation of the rotary switch 1, said contact bridge 48 connects and/or disconnects at least two conducting paths of the printed circuit. Shaped at the switch wheel 4 is a pivot pin 17 which penetrates the circuit plate 7 and which is secured by a base member 5 to the circuit plate 7 on the said's bottom side opposite to the printed circuit. The switch wheel 4 includes catch-type recesses 42, with a resilient switching element 32 engaging into each one recess depending on the position of rotation of the switch wheel 4. The base member 5 urges via the switch wheel 4 the contact lugs 48 resiliently against the circuit plate 7, additionally forms the catch-type element 40 and simultaneously couples the switch wheel 4 and the circuit plate 7.
