Abstract
The response and extinction voltage of a relay are adjusted by displacing an armature, on the one hand, and pole plates, on the other hand, parallel to each other. The extent of each opposing pole face is varied without varying the air-gap distance. This method of calibration is of particular advantage in relation to a reed relay with a bridge contact.
