制御回路。[Claims for Utility Model Registration] A window operation unit that outputs instruction signals for raising and lowering the window glass in opposite directions, a drive motor for automatically raising and lowering the window glass, and a power supply side or ground for switching the raising and lowering operation. two non-locking switching contacts, switchable to the side and normally connected to the earth side, which allow operation in either the up or down direction when only one is on the power side; and said window; a switching contact drive unit that receives an instruction signal based on an operation in either direction of the operating unit and switches the switching contacts on the corresponding side to the power supply side; an opening/closing detection circuit that outputs a reset signal; and detecting that the reset signal is output from the opening/closing detection circuit during operation of the window operating section, and blocking the instruction signal from the window operating section to the switching contact drive section. and a power-stopping circuit that switches the corresponding contact to the ground side.
