To provide a switch circuit capable of reducing the number of ports used in a control device.SOLUTION: A switch circuit 20 comprises a first voltage dividing circuit 511 and a second voltage dividing circuit 521 that are connected in parallel. An electronic control device 24 comprises: an input part 27 to which a voltage dividing point of each of the voltage dividing circuits 511 and 521 is connected via a common input port 27P; and a first switching part 28 and a second switching part 29 that switch between an application state, in which a power supply voltage is applied, and a non-application state, in which no power supply voltage is applied, in cycles that are each constant and are mutually different. An operation switch 21 comprises a lock switch 25 and a release switch 26. When the lock switch 25 is operated, only the first switching part 28, out of the switching parts 28 and 29, is connected to the first voltage dividing circuit 511 and the second voltage dividing circuit 521. When the release switch 26 is operated, only the second switching part 29, out of the switching parts 28 and 29, is connected to the first voltage dividing circuit 511 and the second voltage dividing circuit 521.SELECTED DRAWING: Figure 1

    【課題】制御装置において使用されるポート数の低減を図ることのできるスイッチ回路を提供する。【解決手段】スイッチ回路20は、並列接続された第1分圧回路511および第2分圧回路521を有する。電子制御装置24は、共通の入力ポート27Pを介して各分圧回路511,521の分圧点が接続される入力部27や、電源電圧が印加される印加状態と印加されない非印加状態とを共に一定周期で且つ互いに異なる周期で切り替える第1切替部28および第2切替部29を有する。操作スイッチ21はロックスイッチ25およびリリーススイッチ26を有する。ロックスイッチ25の操作時には各切替部28,29のうちの第1切替部28のみが第1分圧回路511および第2分圧回路521に接続される。リリーススイッチ26の操作時には各切替部28,29のうちの第2切替部29のみが第1分圧回路511および第2分圧回路521に接続される。【選択図】図1
