いずれかに記載の精密リミットスイッチ。[Scope of Claim for Utility Model Registration] 1. A switch supported inside a case via a spring member, and a movable electric contact on one end side of which is biased by the spring member and comes into contact with a fixed electric contact inside the case. It is equipped with a contact whose tip protrudes outside the case, and has a support shaft fixed to the other end that extends perpendicularly to the longitudinal direction of the switch and extends to both sides, and the support shaft is connected to the case side by spherical contact. The contact element contacts the locking part under the bias of the spring member to form a rotation fulcrum for the switch, and the switch rotates due to the contact pressure of the required object that is in contact with the tip of the contact. A precision limit switch characterized by having a structure that separates both of the above contacts. 2. The precision limit switch according to claim 1, wherein the support shaft has a spherical part on at least one end side, and the spherical part fits into a recess formed on the case side and having a circular opening edge. 3. A utility model in which the spindle has a spherical part on at least one end side, and the spherical part is located at the center of three spherical protrusions in a triangular arrangement that protrudes toward the case side, and abuts each of the spherical protrusions. A precision limit switch according to claim 1. 4. A request for registration of a utility model in which the support shaft has a spherical part on one end and a round shaft on the other end, and a spherical protrusion protrudes from the case side to abut the peripheral surface of the round shaft from both sides. range 1
Precision limit switch described in item 2 or item 2. 5. The precision limit switch according to any one of claims 1 to 4 of the utility model registration claim, in which a mechanism for amplifying conduction changes between both contacts is provided inside the case.
