Abstract
827,130. Automatic exchange switches. SIEMENS & HALSKE A.G. April 2, 1958 [April 5, 1957], No. 10639/58. Addition to 797,913. Class 40 (4). In a switch of the co-ordinate type comprising magnetic contacts F1, F2 operable when a pair of intersecting horizontal and vertical coils C, A are energized and held by a further coil H1 which may be horizontal or vertical, and in which a magnetic shunt path via gaps L1, L2 is provided to prevent unwanted operation by the energization of a single coil only, a further magnetic shunt path L3, L4 for the flux due to the hold coil is provided by a re-entrant part of the outer magnetic casing. This prevents unwanted operation of the contacts should a hold coil H1 be energized simultaneously with the operating coil C. The effectiveness of the coil C may also be reduced with the same object in view, either by reducing the current or number of turns of the coil (in which case corresponding increases may have to be applied to coil A) or alternatively by decreasing the reluctance of the magnetic shunt path for the contact F1 as compared with that for F2, e.g. by an asymmetric design of the magnetic shunt so that the crosssectional area of the gap L1 is greater than that for L2.
