Claims (1)

[Scope of utility model registration request] In an astronomical switch equipped with a rotary moderation mechanism and a circuit switching mechanism, the circuit switching mechanism includes a contact pad that is divided into predetermined equal parts per lead on one side of the flank surface of a female thread made of an insulating cylindrical member, and arranged concentrically with the screw core. and an input terminal having an output lead terminal led out from the contact pad in a radial manner at an equal pitch with a spiral lead on the outer cylinder of the female thread, and a ring-shaped contact pad on one end surface of the female thread cylinder. a spiral rotary slider having a convex slide keyed boss supported on a conductor rotating shaft having a key groove and a contact element capable of being wedged into the valley of the female screw and applying pressure to the flank surface; a rotating slider fixed to the conductor rotating shaft so as to be in pressure contact with the ring-shaped pad;
The rotary moderation mechanism consists of inserting the conductor shaft capped with an insulating knob into a flanged bearing made of an insulating member and having equally divided notch grooves on the flange surface, and inserting an elastic cam plate fixed to the conductor shaft and the The notched groove forms a moderation mechanism, and one end surface of the stationary substrate cylinder is fixed concentrically with the flange of the moderation mechanism, and the spiral sliding conductor plate and the rotary slider are connected to each other. A spiral rotary switch, wherein the rotary switch is engaged with the rotating shaft.
