Abstract

The subassembly has a torsion spring (1) with two end arms (3, 3`) deployed in V shape and supported against stops. The spring and the stops are animated with a relative motion such that distance between the stops and a central portion (2) of the spring in translation direction increases while closing air gaps arranged between a core and a magnetic yoke. The spring is symmetrical with respect to a movement axis of a movable assembly.
