Abstract
A rotary type pulse switch includes a movable electrodehaving a plurality of contacting portionsA formed in positions of the same radius from its rotation center, and a fixed electrodedisposed face to face with the movable electrodeand having a plurality of contacted portionsarranged in form of stepping stones on the same circumference as a rotation locus T of the contacting portionsA. The fixed electrodeincludes a first fixed electrode patternA, a second fixed electrode patternB and a common fixed electrode pattern, each of the fixed electrode patternsA,B being in a mutually nonconductive state. The contacted portionsare arranged in such a positional relationship that a full insulation state occurs during rotation of the movable electrodein which none of the contacting portionsA contact the first fixed electrode patternA, second fixed electrode patternB or common fixed electrode pattern
