<P>PROBLEM TO BE SOLVED: To provide a wall-embedded operating device capable of preventing breakage of a circuit of a printed board for liquid crystal display even if a static electricity is applied to a metal plate at the time of contacting by operation. <P>SOLUTION: An illuminance sensor setting device (wall-embedded operating device)7 includes a base body 73 whose front surface is opened and which is embedded in a wall surface, a printed board block 74 which is housed inside the base body 73 to be connected to a signal line, and contains a printed board 74b on which a liquid crystal display part 74a is mounted, and a cover 75 which is arranged on the front surface of the printed board block 74. At the position corresponding to the upper side surface of the liquid crystal display part 74a, related to the cover 75, a rib 75d which protrudes to the printed board block 74 side is formed. With this configuration, an insulation distance between a take-off point and the arriving point of static electricity is increased, to prevent breakage of a circuit of the printed board 74b for liquid crystal display even if a static electricity is applied to the metal plate 78 at the time of contacting by operation. <P>COPYRIGHT: (C)2012,JPO&INPIT |
