Claims

[Scope of utility model registration request]

In a case in which a common electrode, a first electrode for the first switch, and a second electrode for the second switch are provided on the inner bottom surface, there is provided a case that contacts the common electrode and is connected to the first electrode and the second electrode. In a push switch that houses movable contact pieces that face each other at a distance, and elastically deforms the movable contact pieces by a pressing operation to bring the movable contact pieces into contact with the first electrode and the second electrode with a time difference, the movable contact pieces , a dish-shaped disk portion that curves upward, a substantially horizontal overhang portion that is integrally formed on both sides of this disk portion and has a pair of protrusions on the lower surface of both ends, and each of these overhang portions. The conductive metal plate is formed of a single conductive metal plate, and has arm parts that extend diagonally inward from both ends of the straight line passing through the pair of protrusions, and are bent diagonally downward toward the tip. The movable contact piece is supported on the inner bottom surface of the case by bringing the tip of each arm portion into contact with the inner bottom surface of the case, and the tip of at least one arm portion of the movable contact piece is brought into contact with a common electrode on the inner bottom surface of the case. , and when the movable contact piece is pushed down while pressing the disc part and elastically deforming each arm part, at least one of the projections on the lower surface of the overhang that comes into contact with the bottom surface inside the case is moved inside the case. The first switch contact contacts the first electrode on the bottom surface, and the disk portion of the movable contact piece is connected to the initial upper surface when the disk portion is further pressed after each of the protrusions abuts the inner bottom surface of the case. A push switch characterized by having a contact point for a second switch that is reversed from an inflated state to a downwardly inflated state and contacts a second electrode on the inner bottom surface of the case.
