PROBLEM TO BE SOLVED : To provide a polarity-correctable multifunctional connector switch which corrects its polarity for the safe use of electricity, thereby allowing a plug to be inserted with the correct polarity. SOLUTION : A polarity-correctable multifunctional connector switch has a rotary member for rotation. The rotary member is provided with at least one inspection member which is electrically connected to a touch sensor member and a power supply wire terminal of a power supply plug. When the touch sensor member is touched by a hand, it forms a circuit with a human body so that the correct polarity position of the power supply plug is determined, thereby making it possible to select a potential or voltage with an appropriate polarity by means of the rotary member. Also, by using an electric resistance-type indicator lamp, it is possible to determine whether or not an output from an earth E-pole is normal. COPYRIGHT : (C)2012, JPO&INPIT |
