Circuit arrangement for detecting vehicle door position has first switching device in parallel with second/third switching device series circuit, device that taps first device and series circuit

摘要

The circuit arrangement has 3 devices in or on the door or door frame from which switching signals can be received when the vehicle door is fully open or closed in the error-free state and a tapping device for electrically tapping at least one of the devices. The first device is connected in parallel with a series circuit of the second and third devices. The tapping device taps the first switching device and the series circuit. The circuit arrangement has first, second and third switching devices (1-3) arranged in or on the door or door frame of the vehicle and from which a switching signal can be received when the vehicle door is fully open or closed in the error-free state and a tapping device for electrically tapping at least one of the switching devices. The first switching device is connected in parallel with a series circuit of the second and third switching devices and the tapping device taps the first switching device and the series circuit of the second and third switching devices. AN Independent claim is also included for the following: (a) an on-board vehicle electrical system with an inventive circuit arrangement integrated in the form of a 4-pole.
