Liquid level sensor for motor vehicle, has contact unit that is driven by magnetic device on movement path along longitudinal extension of resistance channel in movable manner and in conductive connection with resistance and contact channel

摘要

The sensor has a contact channel (8) that is arranged spaced to a resistance channel (9) and connected under an effect of a magnetic device that is movable by a float assembly such that an electrical connection depending on a position of the assembly is caused. The channels are arranged with a distance to each other, where the distance between the channels is bypassed by a contact unit (15). The contact unit is driven by the magnetic device on a movement path along a longitudinal extension of the resistance channel in a movable manner and is in conductive connection with the channels.
