It may be charged with static electricity of about 10,000 volts. Therefore, when a finger touches the operation push button 2A to transmit a signal to the electric circuit connected to the other end of the control wire 4, the operation switch 2 is attached to the molded panel 1 made of an insulating material. Therefore, the static electricity from the human body has no place to escape, and the static electricity circulates through the insulation of the operation switch 2 to the terminal provided on the back surface, and enters the aforementioned electric circuit via the control wire 4. If this electric circuit includes an electronic circuit that is sensitive to voltage, such as a microcomputer, it will be destroyed by the static electricity, and the electric circuit will not be able to operate normally.
