Claims

[Scope of utility model registration request]

a flexible upper sheet provided with an upper electrode;
A laminate in which a spacer is interposed between a lower sheet and a lower sheet provided with a lower electrode at a position facing the electrode, and a spacer is provided with a through hole that faces the upper and lower electrodes and allows these electrodes to approach and separate from each other. is mounted on a support plate, and the air in the through hole of the spacer is sealed from the outside, and the membrane switch has flexibility through a second spacer on the lower surface of the support plate. A bottom film is laminated, and the second spacer is provided with a second through hole for an air reservoir that penetrates the lower sheet and the support plate and communicates with the through hole. 1. A membrane switch characterized in that the bottom film facing the second through hole is bent in response to changes in the volume of air sealed in the membrane switch.
