ことを特徴とするメンブレンスイツチ。 By arranging the electrode surfaces of an upper sheet having electrodes on one surface and a lower sheet having electrodes on one surface facing each other via a spacer, placing an elastic click spring on the upper sheet, and pressing the click spring. In the membrane switch, when the electrode on the upper sheet is brought into contact with the electrode on the lower sheet and the pressure on the click spring is released, the click spring is reversed and returns to its original state. Spherical and solid,
A rigid spring support is arranged on the upper sheet, and the spring support is provided with a recess for accommodating the click spring, and the inner bottom surface of the recess is aligned with the near-spherical surface of the click spring after inversion. A membrane switch characterized by forming a near spherical surface.
