ABSTRACT:
In multiple position rotary switch a pair of printed circuit boards are arranged adjacent opposite sides of a single brush bearing rotatable element. Brush blocks have a plurality of contacting extensions which may be selectively deleted in accordance with circuit design. The rotatable element includes an integral wheel having peripheral means in association with a detent in the housing for particularly positioning the wheel relative to the circuit boards for selectively connecting circuits thereon to establish desired switch connections.
