Claims

[Scope of Claim for Utility Model Registration] A first fixed contact for a first switch, a second fixed contact for a second switch, and a common contact are provided inside the switch case and are provided in contact with the common contact. When the first switch is pressed, it is elastically deformed and comes into contact with the first fixed contact with a click action, and when the first switch is further pressed after being turned on, it is further elastically deformed and brought into contact with the above-mentioned first fixed contact with a click action. A movable contact for a push switch that comes into contact with a second fixed contact, which includes a disc part to be pressed, an annular frame plate part surrounding the outer periphery of the disc part with a gap in between, and It consists of one metal plate having a shape consisting of a pair of connecting plate parts that connect the inner peripheral edge of the frame plate part and the outer peripheral edge of the disc part on a diameter line passing through the center, and the disc part has an upper bulge. The frame plate portion is formed in the shape of a plate that curves inwardly, and the entire circumference of the frame plate portion is formed in the shape of a disc spring that slopes upward from the outer peripheral edge of the frame plate portion toward the inner peripheral edge, and each of the pair of connecting plate portions is While tilting upward from the frame plate portion to the disc portion,
A bent portion is formed on both sides of the frame plate portion, with a portion projecting upward at a portion that passes through the center of the disc portion and intersects with a straight line orthogonal to the diameter line, and A support part is placed on the pair of movable contact receivers in the switch case, and at least one of the support parts is connected to the common contact provided on the movable contact receiving surface of at least one of the pair of movable contact receivers. and a connecting portion between at least one of the pair of connecting plate portions and the disc portion to contact the first fixed contact by reversing the entire circumference of the frame plate portion to a downwardly inclined state. A contact portion for a first switch is formed, and a center portion of the disk portion serves as a contact portion for a second switch that comes into contact with the second fixed contact by inverting the disk portion to a downwardly swollen state. Movable contact for push switch.
