ABSTRACT:
A rotary switch having a plurality of outputs energized according to a prearranged pattern during rotation of a shaft of the switch includes first and second switch boards spaced apart and having respective contact portions formed on the facing surfaces thereof. The contact portions of the first board include an arcuate collector and a plurality of fixed contacts arranged in a predetermined pattern, and the second board includes a plurality of fixed contacts arranged in a predetermined pattern. A slider is held rotatively between the switch boards and has two pairs of electrically-connected conductive arms with a respective pair of conductive arms extending towards the contact portions of each board. In this way, each of the fixed contacts can be connected electrically with the arcuate collector in a predetermined pattern as the slider is rotated.
