Claims (1)

[Claims for Utility Model Registration] A ring-shaped collector electrode and first and second comb-shaped electrodes arranged coaxially and adjacent to each other around the ring-shaped collector electrode are formed on an insulating substrate, a first contact portion that is in sliding contact with the first or second comb-shaped electrode; and a second contact portion that is in sliding contact with the first or second comb-shaped electrode.
A slider having a contact portion is mounted around the center of the collector electrode as a rotation center, and closing between the first comb-shaped electrode and the collector electrode,
A pulse switch that outputs a first contact signal indicating an open state and a second contact signal indicating a close state or an open state between the second comb-shaped electrode and the collector electrode, the first and second comb-shaped electrodes comprising: Each comb has a shape that is symmetrical about a predetermined straight line passing through the rotation center, and has m (m is an integer of 2 or more) comb teeth, and the pitch of the teeth is determined by the rotation The height is 360/2 m (degrees) when viewed from the center, one of the two separation intervals separating the first and second comb-shaped electrodes is set shorter than the other, and the distance between the second contact portion of the slider The first and second sliding contacts with the first and second comb-shaped electrodes are on any straight line passing through the center of rotation, and are arranged to face each other across the center of rotation.
