PURPOSE: To equalize operation force for a switch of a desired size by keeping an interval between both electrodes in insulation sheets having the electrodes and spacers on facing surfaces each other by thickness of the spacers, and setting aperture sizes of the spacers at both electrode parts to be different from each other.

CONSTITUTION: Electrodes 3a, 3b, and spacers 4a, 4b are provided on facing surfaces each other in two insulation sheets 2a, 2b, and both spacers 4a, 4b are connected to each other to keep an interval (d) between both electrodes constant. A display sheet 5 for names of switches, etc., is attached to a front surface of the sheet 2a, and the switch is pushed by a finger 7 to deform the sheets 5, 2a, so the electrodes 3a, 3b get in contact with each other. Aperture sizes La1 and Lb1 of the spacers 4a and 4b are set to have a relation of La1>Lb1, and their thicknesses are also set to be different from each other as necessary. An operation force of the finger 7 for the switch which is small for the effect of design can be set small, and the operation force for the switch of a desired size can be equalized.
