Abstract
A trimming potentiometer (10) has a circuit track pattern (12) disposed on a base (11) having three integrally formed legs (11d). The track pattern (12) includes a collector track (12a), a resistance track (12b) and a pair of termination tracks (12c) connected to opposite ends of the resistance track (12b). Terminals for the device are formed by extending the collector track (12a)and the pair of termination tracks (12c) down the middle leg (11d) and the opposite outside legs (11d), respectively. A multi-functional contact (13) is rotatably mounted on the base (11) and includes multiple fingers (13g) that contact the resistance tracks (12b), dimpled areas (13j, 13k) which form projecting surfaces that contact the collector track (12a), a stop tab (13l) at its upper extremity that limits rotation, and outwardly extending notched tabs (13m) for receiving a suitable drive member to adjust the setting of the potentiometer (10).
