Membrane switch and pressure sensitive sensor
First Claim
1. A membrane switch, comprising:
- a pair of electrode sheets having electrodes formed respectively on opposite surfaces of a pair of sheetlike base materials disposed oppositely, the electrodes constituting a contact portion;
a spacer interposed between the pair of electrode sheets so that the electrode sheets are opposed to each other with a predetermined interval spaced therebetween, the spacer having a hole formed in a position of the contact portion; and
an adhesive for bonding the spacer between the pair of electrode sheets, wherein the adhesive on at least one surface side of a peripheral portion of the hole of the spacer is removed.

Abstract
A pressure sensitive sensor is composed of a pair of upper and lower electrodes sheets 1 and 2 disposed oppositely, a spacer 3 interposed between both of the sheets 1 and 2, and adhesives 4 and 5 between these electrode sheets 1 and 2 and spacer 3. In the spacer 3, a hole 31 is formed in a position of a contact portion 6. A diameter of this hole 31, convex portions 13 and a pressure sensitive electrode 22 are set in such a positional relationship that a peripheral portion of the hole 31 is overlapped between the convex portions 13 and the pressure sensitive electrode 22. Then, the adhesives 4 and 5 open more largely than the diameter of the hole 31 of the spacer 3 so as to be removed from the peripheral portion of the hole 31 on both surfaces of the spacer 3.
