To provide a vehicle power supply circuit which standardizes a circuit and enhances versatility even when specification of a switch circuit is different.SOLUTION: A vehicle power supply circuit 10 includes a resistor which is arranged in parallel to an exciting coil 13 of a relay circuit 12, and of which a positive electrode side (one end) is connected to negative electrode sides (other ends) of a plurality of switch circuits 11A, 11B and a negative electrode side (other end) is grounded. Therefore, a rating value of a current flowing from a power supply B to the first switch circuit 11A itself is set to the switch circuit 11A out of the plurality of switch circuits 11A, 11B. Even when specification is different from the second switch circuit 11B, a desired current can flow to the switch circuit 11A with the rating value set by using the resistor 15 as a simple circuit element.SELECTED DRAWING: Figure 1

    【課題】スイッチ回路の仕様が異なる場合でも回路を標準化して汎用性を高めることができる車両用電源回路を提供する。【解決手段】車両用電源回路10は、リレー回路12の励磁コイル13に並列に配置され、正極側(一端)が複数のスイッチ回路11A,11Bの負極側(他端)にそれぞれ接続すると共に負極側(他端)が接地される抵抗器を有する。このため、複数のスイッチ回路11A,11Bのうち第1のスイッチ回路11Aに電源Bからスイッチ回路11A自身に流れる電流の定格値が設定され、第2のスイッチ回路11Bとの間で仕様が異なる場合でも、簡素な回路素子である抵抗器15を用いることで、その定格値が設定されたスイッチ回路11Aに所望の電流を流すことができる。【選択図】図1
