As shown in FIGS. 5 and 5, an insulating substrate 53 having a switch matrix X pattern 51 and an output Y pattern 52 is mounted on a base substrate 50, and a spacer 54 is further mounted thereon. An insulating sheet 55 having a switch matrix Y pattern 52 'is placed thereon. Here, as shown in FIG.
5, the Y pattern 52 'on the insulating substrate 53 and the Y pattern 52 on the insulating substrate 53 are in pressure contact with each other by the pattern pressure contact rigid cover 57 sandwiching the elastic rubber 56 being fastened to the base substrate 50 with the screw 58.

も問題であった。Problems to be Solved by the Invention However, in the above-mentioned conventional membrane switch, since the elastic body for pressure contact is the elastic rubber 56, there is a drawback that the elastic rubber 56 is permanently strained due to environmental resistance. According to the experiment, when silicone rubber having a hardness of 50 ° was used as the pressure-bonding rubber, a permanent strain of about 3 to 7% was confirmed in an environment resistance test when 20% compression was performed. This means that the pressure contact force itself decreases in the environment, and there is a problem in terms of reliability. Furthermore, if the number of patterns to be pressed is increased, it is necessary to press the parts other than the patterns as well, so that the area required for the pressing is increased, and a very large force is required. Further, since the parts are composed of the elastic rubber 56 and the rigid cover 57 for pressure contact, there are problems in man-hours, parts cost, investment in molds and the like.
