Rotary Potentiometer with Molded Terminal Package Abstract A rotary potentiometer (10) having an insert molded thermo- plastic resin body (12) with an annular groove (14) disposed therein about a central post (19) having an aperture (16) therethrough. A resistive element (26) is disposed about the periphery of the groove (14), an actuator arm (20) is attached to one end of a metallic shaft (18) journalled in said aperture (16) in the central post (19), and a return spring (28) has one end (29) captured within a drop slot (13) at the perimeter of the groove and the other end (31) secured in slot (11) of the shaft (18) for returning the actuator arm (20) and drive arm (22) to their initial position. A drive arm (22) has a rake type contactor (33), the drive arm (22) being secured to the operating end of the shaft (18). A terminal coupling subassembly (65) is posi- tioned within a receiving well (40) in the potentiometer body (12), and is captured within the body by securing a cover (80) over the receiving well (40). The plurality of terminals (60-62) in the coupling subassembly (65) have angled ends (72) for resilient contact with terminations of the resistive element (26) and terminal connec- tion ends (55) molded within the potentiometer body (12).
