ABSTRACT:
An improved shaft-operated rotary switch construction for printed circuitry applications is disclosed. The improved switch is a modular design incorporating a standardized rotor element accommodating the mounting of wiper contacts in different positions and different operational orientations. Also disclosed is an improved releasable clutch mechanism providing one mode of operation in which the rotors of different switch sections are coupled together for simultaneous rotation, and another mode in which they are rotatable independently, the operating mode being selected by axial movement of one section's operating shaft relative to that of the other.
