PURPOSE:To prevent breakdown of an electric circuit due to static electricity by providing an electrostatic induction means which is insulated from an electronic circuit, mounted with a remote controller on a metal switch box and electrically communicated with the switch box. CONSTITUTION:A metal member 9 which is provided as an electrostatic induction means is inserted pressingly into and fixed to an upper case 11. In this instance, the metal member 9 is inserted pressingly into a mounting hole of the upper case 11 and works also as a seat for a mounting screw. When a remote controller is mounted by the mounting screw on a switch box through a mounting hole 15a, the electrostatic induction metal member 9 is electrically communicated with the switch box through the mounting screw. At this time, if the switch box is earthed, the remote controller is also earthed through the switch box. Further, discharged static electricity invading from a space 3 does not reach a terminal stand 16, but is induced to the metal member 9 near the terminal stand 16. Then the static electricity reaches the earth through both the mounting screw and the switch box. |
