電気機械開閉器
Document Type and Number:
Japanese Patent JP4358308
Kind Code:
B2
Abstract:
An electromechanical switching device includes at least one moveable contact and an associated drive in a device housing. Magnetic field sensors which are disposed at a suitable location inside and/or outside the device housing detect magnetic field values that are each linked to one of a plurality of switching states. The device housing has a switching handle which is intended for manual release. Through the use of a miniature inductance element with a ferrite core as a highly sensitive magnetic field sensor, a position of the switching handle or of a part coupled thereto is monitored and/or a current flowing in the switching device is detected.
