PROBLEM TO BE SOLVED: To provide a switching device that enables a user to set whether the operation state of control target equipment on standby is displayed or not.SOLUTION: A first controller 101 turns out all light emitting diodes 121 to 128 when operation buttons 111 to 114 have not been operated and have been on standby for a predetermined time or more. When any one of the operation buttons 111 to 114 is operated, the first controller 101 turns on or out the corresponding light emitting diodes 121 to 128 according to the operation sate of control target equipment at the operation time point. According to a long push operation of the operation button 111, for example, a calculation processor 10 sets whether the display of the light emitting diodes 121 to 128 on standby is set to be valid or invalid. When the calculation processor 10 sets that the display of the light emitting diodes 121 to 128 on standby is set to be valid, the first controller 101 turns on or out the corresponding light emitting diodes 121 to 128 according to the operation state of the control target equipment even in a standby state. |
