Abstract
A method of ascertaining the position of rest assumed by a movable armature, in response to forces of oppositely acting return springs, between two deenergized electromagnets. The method includes the following steps: measuring the inductivities of the two electromagnets; comparing the measured inductivity values to obtain a comparison value; and ascertaining the position of the armature in the position of rest between the two electromagnets from the comparison value.
