Tracks (50,56) are assembled on PCB plate (22). Carrier supports cursor with flexible outer arms (66,70) whose contacts (68,72) make and break contact with tracks by switching using toothed rings (76,78) and spring (44). Extension link (74) coupled to cam track (84) and arm (66), supports contact (68) so that link lifts off contact from track during switching, if intervention of contacts occur.
