Abstract: A multiple position rotary switch is disclosed for incorporation into an electrical device. The switch comprises an annular cup that serves as a housing for the switch and which receives a knob for rotation therein. The knob is retained within the cup by a circuit board that is removably secured to the cup. The circuit board includes a first major surface having a switching circuit formed thereon and a second major surface. The circuit board is removably secured to the cup by a plurality of barbed ears which extend from the sidewall of the cup such that the first surface of the board is located between the knob and the second surface of the board. The cup includes an upstanding sidewall and a race against which the knob rotates. The race includes a plurality of protrusions which facilitate the retention of the knob in preselected positions as the knob is rotated. The knob comprises a cylindrical disk having on one surface a handle.
