Claims

[Claims for Utility Model Registration] 1. A device comprising a single fixed electrode disposed in the center of a box-shaped base and a plurality of fixed electrodes disposed around the fixed electrode, A dome-shaped leaf spring disposed in a space above the pole and the single fixed electrode is expanded and deformed by pressing a push button, and the plurality of fixed electrodes and the single fixed electrode are connected to each other via the dome-shaped leaf spring. In a push button switch capable of establishing an electrical connection with an electrode, a contact point is provided at a portion of the dome-shaped leaf spring that faces the single fixed electrode and a portion that faces each of the plurality of fixed electrodes. A push button switch characterized by having a protruding portion. 2. The push button switch according to claim 1, wherein the single fixed electrode and the plurality of fixed electrodes are formed on the same surface as the electrode arrangement surface of the base. 3. The dome-shaped leaf spring is formed into a substantially polygonal shape with contact portions provided at opposing portions of the plurality of fixed electrodes serving as vertices, and each of the contact portions contacts the plurality of fixed electrodes when the push button is pressed. A pushbutton switch according to claim 1 or 2, characterized in that they are in sliding contact, respectively.
