SWITCH CIRCUIT, SWITCH DEVICE, AND SYSTEM

A switch circuit includes a first circuit including a first switch, and a second circuit including a second switch. The first circuit and the second circuit are connected in series. The first circuit has a circuit configuration in which a combination of resistors in a signal path between output terminals of the first circuit differs depending on the electrical conduction state of the first switch. The second circuit has a circuit configuration in which a combination of resistors in a signal path between output terminals of the second circuit differs depending on the electrical conduction state of the second switch.
