FIELD: electricity.
SUBSTANCE: invention relates to magnetic actuation mechanism for an automatic switch. The magnetic actuation mechanism (100) for an automatic switch, in particular, for a medium voltage vacuum automatic switch is offered, which comprises: a coil (101), a core (102) and a mobile plate (106). The crest-shaped core (102) intended for arrangement of the coil (101) has the central core (103) which is located between permanent magnets (122) and lateral rods (104, 105) of the core (102). The mobile plate (106) is attracted by the core (102) due to the magnetic field created by the permanent magnets (122) and the coil (101). The mobile plate (106) triggers the automatic switch (500) when it is attracted by the core (102). The first connecting element (110) for connection of the magnetic actuation mechanism (100) with the element of the structure of the automatic switch (500) is offered, and the first connecting element (110) is connected to lateral rods (104, 105) of the core, but not to the central rod of the core (102).
EFFECT: providing the version of reliable fastening of the actuation mechanism.
