摘要： 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. Along its opposite surface the knob includes a plurality of wipers that rotate with the knob and contact the switching circuit formed on the first surface of the circuit board. The wipers selectively close the switching circuit when the knob is rotated to preselected positions. The second surface of the circuit board includes a plurality of plated-through openings which are electrically connected to the switching circuit. The openings each include an upstanding pin that facilitates the connection of the switch to an electrical device.
