Abstract (en)
[origin: EP0984477A2] Two yoke metal sheets are held at a given spacing and are fixed at a mean spacing, to determine the magnetic properties of the actuator, after application of contacting points. Before the contact points are applied, the capacitance formed by the yoke metal sheets and the air gap is periodically determined and compared with a preset rated value. The yoke metal sheet spacing, at the attained rated value, is held constant. An Independent claim is included for the manufacturing mechanism.
