<p>PROBLEM TO BE SOLVED: To provide a composite switch device in which there does not exist any cable wiring between a switch mounted on a rotor and a main body.SOLUTION: A composite switch device 101 includes: a fixed body 1; a rotor 3 rotatably supported with respect to the fixed body 1; a plurality of switches 6 disposed in the rotor 3; a control part 9 disposed in the fixed body 1 which communicates with the plurality of switches 6; a fixed body side coil C2 connected to the control part 9; and a rotor side coil C4 to be electromagnetically induced by the fixed body side coil C2. The control part 9 includes: a power supply circuit SC for supplying power to the fixed body side coil 9; a current detection circuit KC for detecting a current value flowing through the fixed body side coil C2; and a processing circuit TC for outputting a signal corresponding to the detected current value. The plurality of switches 6 are connected in parallel to the rotor side coil C4, and a plurality of resistors 8 are respectively connected between the rotor side coil C4 and the plurality of switches 6, and the resistance values of the plurality of resistors 8 are different from each other.</p> |
