PROBLEM TO BE SOLVED: To provide a switch device for an on-vehicle power source capable of quickly controlling a switch.SOLUTION: A switch device 3 comprises switches 31, 32, a ground fault information detection unit 35, and a single control circuit 34. The switch 31 is connected between a power storage device 1 and a load 4. The switch 32 is connected between a power storage device 2 and the load 4. The ground fault information detection unit 35 detects an electric detection value for determining presence or absence of occurrence of a ground fault on the power storage device 1 side and a ground fault on the power storage device 2 side. The control circuit 34 is connected to the ground fault information detection unit 35 and control ends of the switches 31, 32 and controls the switches 31, 32 based on the detection value of the ground fault information detection unit 35.SELECTED DRAWING: Figure 1
【課題】速やかにスイッチの制御を行うことができる車載電源用のスイッチ装置を提供する。【解決手段】スイッチ装置3はスイッチ31,32と地絡情報検出部35と単一の制御回路34とを備える。スイッチ31は蓄電装置1と負荷4との間に接続される。スイッチ32は蓄電装置2と負荷4との間に接続される。地絡情報検出部35は蓄電装置1側の地絡および蓄電装置2側の地絡の発生の有無を判断するための電気的な検出値を検出する。制御回路34は地絡情報検出部35およびスイッチ31,32の制御端に接続され、地絡情報検出部35の検出値に基づいてスイッチ31,32を制御する。【選択図】図1
