An actuation mechanism (27) for an elevator safety gear (20) comprises an engagement element (29), at least two permanent magnets (32, 34) and at least one electric coil (46, 46a, 46b). The engagement element (29) is movable between an engaged position in which it engages with the guide member (14, 15) of the elevator system (2) and a disengaged position in which it does not engage with the guide member (14, 15) of the elevator system (2). The at least two permanent magnets (32, 34) are arranged in a configuration generating a repulsive force (FR) between the at least two permanent magnets (32, 34) and urging the engagement element (29) towards the engaged position. The at least one electric coil (46, 46a, 46b) is configured for generating an electromagnetic force urging the engagement element (29) towards the disengaged position and/or for holding the engagement element (29) in the disengaged position, when an electric current is flowing through the at least one electric coil (46, 46a, 46b).
