Claims

[Scope of utility model registration request]

It consists of a synthetic resin case body with one side open and a synthetic resin cover that covers the open side of the case body, and includes a switch case with a built-in contact mechanism and a rotating shaft supported by the switch case. a cam fixed to a rotating shaft within the switch case, an operating lever connected to the rotating shaft to drive a contact mechanism via the cam, and a cam and a cam disposed within the switch case. A spring member that constantly applies a return force to the operating lever via the rotation shaft, a pin formed on the opposing end surface of either the case body or the cover, and a pin formed on the other opposing end surface corresponding to the pin. A limit switch characterized in that the pin has a polygonal cross section, and the pin is press-fitted into the pin hole having a circular cross section to connect the case body and the cover.
