ABSTRACT:
A device (1) suitable for moving a body (2) along a linear path (F) between two predetermined positions, and comprising: first and second electromagnets (5, 8) respectively having first and second moving cores (6, 9) that are secured to the body and that are arranged to have axes of action (7, 10) on the body that are parallel to the path (F), and a permanent magnet (11) associated functionally with the first core (6) and disposed to co-operate magnetically and functionally therewith when the body finds itself in its first position, and preferably return means (13) that are associated with the body so as to urge it back from the second position to the first position when the second electromagnet (8) is not excited.
