Abstract (en)

The invention relates to an actuator for use in a tripping device or a switch, comprising a flat coil (2), a fixed power source (3) and a movable magnetic armature (4), whereby the fixed power source is constructed in such a way that the force exerted by the fixed power source (F s1 ) keeps the movable magnetic armature in a first position (5) spaced apart from the flat coil, whereby the flat coil is constructed in such a way that during current having at least a certain strength is flowing through the flat coil the attractive magnetic force (F m ) exerted by the flat coil is larger than the force of the fixed power source to transfer the movable magnetic armature from the first position to a second position at or near the flat coil, whereby the movable magnetic armature is in the second position closer to the flat coil than in the first position. The invention further relates to a tripping device and a switch comprising a least one such actuator.
