According to the invention, an electromagnetic actuator (1) for a switch, operating in the medium voltage range, comprising at least one magnet body (2, 3), defining an air gap, a moving body (5), arranged in the air gap (4), guided to move relative to the magnet body (2, 3), at least one permanent magnet and at least one conductor (6), through which a current may flow, whereby the conductor(s) (6) extend(s) at least partly into a magnetic field generated by the permanent magnets on a movement of the moving body (5), may be produced such as to be able to be fixed in the end positions thereof in a simple manner, whereby the moving body (5) is fixed to at least one soft-magnetic locking body (7) and the magnetic field generated by the permanent magnet(s) (3) flows through the locking body (7) in an end position of the moving body (5) in which the air gap (4) for the magnetic field is bridged by the locking body (7).
An electromagnetic drive (1) for a switch, in particular in the medium-voltage sector, having at least one magnet body (2, 3) which delimits an air gap, a moving part (5) which is arranged in the air gap (4) and is guided such that it can move with respect to the magnet body (2, 3), at least one permanent magnet and at least one conductor (6) to which current can be supplied, the conductor(s) (6) extending at least partially in a magnetic flux produced by the permanent magnet(s) in the event of a movement of the moving part (5),
