Abstract

677,648. Fusible cut-outs. SANDERS & CO., (WEDNESBURY), Ltd., W., BAYLISS, G. H., and MANION, E. B. Oct. 10, 1950 [Aug. 15; 1949], No. 21144/49. Class 38 (i). In a fuse assembly having fuses of different ratings or characteristics and fixed contacts which are screened by a shield 10 provided with openings through which the carrier contacts are inserted, the openings are surrounded by ribs 11 of a configuration conforming to the shape of the carrier bases A1, A2; A3, and having a gap 11a or gaps 11b, 11e which will receive a projection 12a on the carrier A1 or the projections 12b, 12c on the carriers A2, A3, respectively, so that only the correct carrier can engage a specified set of fixed contacts. Preferably the height of the ribs is such that, if the incorrect carrier is inserted, the projections 12a, 12b, 12c abut the top thereof and prevent the carrier contacts 13 reaching the fixed contacts. Alternatively projections 15a, 15b, 15c from the shield near the openings engage corresponding recesses 16a, 16b, 16c in the carriers. In a still further modification, the carriers have projections to engage complementary apertures in the shield. Specification 621,316 is referred to.
