Abstract
A sealed rotary switch has electrical contacts insert-molded in a stator. The stator has generally open ends which are closed by a pair of covers. The joint between the covers and the stator includes a notch filled with adhesive sealant. The covers have aligned openings in which a rotor is mounted for rotation. Each cover has a seat formed around its opening, with a resilient seal member located in the seat and sealing against the rotor.
