Abstract (en)
[origin: EP1071108A2] A rotatably mounted rocker (23), whose location is fixed w.r.t. the actuator, is provided with a first arm (22) coupled to an armature (16) and a second arm (24) acting on one end of a captive spring (29). The other end of the spring is fixed. The rocker is arranged so that the articulation point of the spring bends along a dead-point line extending through the pivot point and articulation point when triggered, so that the force of the spring keeping the armature (16) in its rest position is reduced.
