Abstract (en)
[origin: EP1137032A2] The invention relates to a magnetic switch having a yoke (1) which has the shape of a rotationally symmetrical cup (3) on the base (4) of which is arranged a permanent magnet (5). The flux of the permanent magnet (5) is conducted via a core (6), which has a radial core flange (8), to the plate-shaped armature (11). For the operational air gap effective between the armature (11) and the core (6) and the yoke (1) and the magnetic resistance WA thereof, the following relation applies in relation to the marginal air gap (10) formed between the core flange (8) and the yoke (1): WA < WR. As a result of the rotational symmetry with a yoke (1) having the shape of a cup (3), it is possible to generate a high holding force for the armature (11) with a small structural volume. <IMAGE>
