Abstract
A subminiature rotary coded switch having a dual-in-line configuration. Flexible contacts making electrical connection with the dual-in-line terminals of the switch are mounted within a stationary body. A drum-shaped detenting cover has printed circuitry on its inner cylindrical surface, typically in the form of a flexible printed circuit board. The cover rotates the flexible board with respect to the body, producing a wiping action with respect to the flexible contacts, thereby producing the desired switching operations. Each such switch can be electrically equivalent to four single-pole double-throw switches and two of the switches of this invention can be mounted in one conventional 14-terminal dual-in-line array of holes in a printed circuit board.
