Claims

[Claims for Utility Model Registration] A. A common contact provided approximately in the center of the bottom surface, at least one fixed contact provided at a position away from the common contact, and a common contact provided in the direction in which the common contact and the fixed contact are arranged. A case comprising a chevron-shaped protrusion and a cylindrical part protruding from the upper surface; A toggle lever having a hole in the axial direction; C a spring inserted into the hole of the toggle lever; D; the biasing force of this spring presses the tip of the spring against the chevron-shaped protrusion, causing the toggle lever to perform a snap action. a push rod, E a protrusion provided at the rotating end of the lever and protruding in a direction perpendicular to the rotational direction; G is formed by an insulating converter that performs a switching operation as a rotation fulcrum, and two approximately triangular conductive spring plates supported by the insulating converter and bent into a U-shape and facing each other. The apex portions of the plates facing the connecting portion grip and contact the common contact, are provided on the sides adjacent to the U-shaped connecting portion, are folded outward from each other, and perform a guiding operation when sandwiching the fixed contact. A toggle switch consisting of a movable contact piece equipped with a guide piece.
