Abstract

1,169,684. On-load air-break switches. E.M.P. ELECTRIC Ltd. 30 Jan., 1967, No. 31543/68. Divided out of 1,158,788. Heading H1N. An on-load air break interrupter has fixed contacts 53, main and auxiliary blade contacts 54, 62 and a main operating shaft 58 supported and insulated by a chassis 51 of moulded or cast insulating material. A quick-acting spring drive mechanism 52, arc shoots (63) for the auxiliary blades, terminals 65 and earthing contacts 66, 69 are also carried by the chassis 51. A transparent cover (not shown) and interphase barriers 61 may be provided.
