Abstract (en)
[origin: EP0292849A2] 1. Electrical switchgear with switch position indication. 2.1 Known electrical switchgear with indicating devices for indicating their switch positions require a high production cost, on the one hand, during manufacture and assembly. On the other hand, incorrect indications cannot reliably be prevented, as a result of large manufacturing tolerances or continued wear. 2.3 The switch position indication according to the invention comes into use only when the contacts are switched off, i.e. separated. The simple design, in which a further indicating lever 24 is arranged on a lever 22, which is required anyway, leads to an effective indication, whose production requires no additional cost. 2.4 Switch position indications are used for electrical safety and are advantageously used in installation equipment.
