ABSTRACT:
A rotary plural contact switch in which a walking-beam-like conductor is incrementally moved to break electrical contact with stationary contacts. This movement is brought about by a revolvable cam rotor. The basic double-contact mechanical structure may be multiplied; thus, switching functions related to digital circuits can be performed. The switch is particularly adapted for small-size embodiments. The external portion of the contacts are spaced to enter an integrated circuit socket, or a printed circuit board having terminals spaced according to the standard grid.
A tang on the internal portion of each contact is used to assemble the insulating enclosure of the switch by simple linear pressure upon the housing and the base parts of the enclosure.
