ON-LOAD REDUCING METHOD OF MEMBRANE SWITCH AND MEMBRANE SWITCH

摘要

PROBLEM TO BE SOLVED: To provide an on-load reducing method of a membrane switch capable of reducing on-load and to provide a membrane switch. SOLUTION: The membrane switch has an upper sheet 5a and a lower sheet 5b arranged so as to face each other; an upper electrode 7a and a lower electrode 7b selectively installed in the facing surface of the upper sheet 5a and the lower sheet 5b; and a spacer 6 arranged the upper sheet 5a and the lower sheet 5b and having an opening 6a in the position matching with the upper electrode 7a and the lower electrode 7b, and the switch is turned on by the contact of the upper electrode 7a and the lower electrode 7b, and a protrusion 3 protruding in the direction opposite to the opening 6a of the spacer 6 is installed in a region (a switch part 4) where the upper electrode 7a in the upper sheet 5a is installed.
