Abstract (en)
[origin: EP0015228A1] 1. Remote-controllable actuation device (1) for switching on and off electric protective switches comprising an electromagnet (5) and an actuation slide (4), which can be moved by means of the armature (8) of the electro-magnet (5) via a lever mechanism, for the operating handle (2) of the protective switch, characterized by the following features ; a) a two armed lever (17), which at its one end co-operates with the actuation slide (4), supports a coupling member (coupling bolts 17b, 17c) on each side of a stationary pivot bearing (11) ; b) an actuator (12), which is flexibly linked with the armature (8) of the electro-magnet (5) and upon which a past dead centre spring (16) fixed to the magnet coil (6) acts, possesses a central member (12c) which serves for guidance agains the coupling members (coupling bolts 17b, 17c) of the two-armed lever (17) and which is widened in such a manner that when the armature (8) is reset into its rest position, the actuator (12) is guided via the dead centre and thus, following the performance of a switching action when the armature (8) is reset into its rest position, the actuator (12) is automatically separated from the one coupling member (e.g. coupling bolt 17b) and brought into engagement with the other coupling member (e.g. coupling bolt 17c) in order to prepare the reverse switching action, c) at its free end, the actuator (12) possesses two hooklike extremities (12a, 12b) which open towards opposite sides and interact with the coupling members (coupling bolts 17b, 17c).
