Title: Rotary pulse switch
Abstract:
A rotary pulse switch wherein either one of two circuits can be selected depending on the direction of rotation of a turn shaft, and the selected circuit can be turned on and off consecutively. The switch includes a rotor having a conductor portion comprised of a ring-shaped common portion and a plurality of radially extending rotary contact portions. An insulating shutter plate is disposed between the rotor and contacts engageable therewith. The contacts include two adapted to engage the rotary contact portions and a single contact adapted to engage the common portion. Rotation of the shutter plate in either direction will electrically isolate one of the two contacts while electrically connecting the other of the two with the rotary contact portions.
