Abstract
Official abstract text for this publication.
A switching device for an elevator door provides a door contact signal. The switching device includes a magnet, a plurality of proximity sensors, and a detection area, which area is adjoined by the proximity sensors and in which the magnet can be moved. A sensor signal can be generated by each of the proximity sensors in at least one position of the magnet in the detection area, wherein the sensor signals are dependent on the distance from the magnet to the proximity sensors. A method for providing the door contact signal utilizes the switching device.
First claim
Opening claim text (preview).
The invention claimed is: 1. A switching device for an elevator door for providing a door contact signal, the switching device comprising: a detection space formed in the switching device; a plurality of proximity sensors adjoining the detection space; and a magnet movable in the detection space, wherein in at least one setting of the magnet in the detection space the magnet generates a sensor signal from each of the proximity sensors to provide compensation, on a basis of eva…
