Abstract

1,202,024. Electromagnetic contactors. ARROW ELECTRIC SWITCHES Ltd. 7 Feb., 1969 [9 Feb., 1968], No. 63444/69. Divided out of 1,202,022. Heading H1N. An electromagnetic contactor has a two-part moulded insulating housing and a supplementary switching unit which has its insulating casing interlocked with the housing parts such that the supplementary unit cannot be removed whilst the housing parts are coupled together. As described the supplementary unit, which may be an extra contactor pole or an auxiliary contact set has a dovetail projection fitting in a corresponding slot in one housing part or vice versa with the other housing part closing the end of the slot as described in Specification 1,202,022.
