Abstract (en)

[origin: EP0308847A1] Coil comprising in particular a cylindrically shaped conductive cup (1) connected to a current intake (33), a winding (23) arranged inside the said cup and one end (14) of which is connected to the cup, in order to produce a magnetic field along the axis of the cup, a conductive core (7) connected to the other end of the winding (12) and situated at the centre of the winding, as well as a fixed switching contact arranged in front of the coil, in relation to the said cup, inside the magnetic field which it produces, and electrically connected to the said core. <??>The winding is built up with the aid of a flat conductor (8) wound on the core, over several turns, at the same time as an insulating sheet, and means (16, 9) are provided for compressing the winding. <IMAGE>
