ABSTRACT:
A switch assembly is adapted for insertion into an aperture formed in an instrument panel. The aperture has opposing edges. The switch assembly includes a body insertable into the aperture and having opposing sides. A base is connected to the body and includes integrally molded first and second retention arms extending therefrom. Each arm has a first end connected to the base and a second end configured to abut against a respective one of the opposing edges to retain the body in the aperture. Each arm has an upstanding rib between the first and second ends facing the respective opposing side of the body. Each rib extends sufficiently from the respective arm to abut the respective opposing side of the body when the second end of the arm abuts the respective opposing edge, thereby increasing the force required to remove the body from the aperture by forming a fulcrum between the first and second ends of the arms. A rotary potentiometer is housed within the body, and a control knob is engaged with the rotary potentiometer. The control knob has first and second integrally molded radial stopper edges. First and second stop portions are integrally molded with the body and engageable with the first and second stopper edges, respectively, for limiting rotary travel of the potentiometer.
