Abstract
1464582 Electric switches ARROW-HART Inc 3 April 1974 [4 April 1973] 22080/75 Divided out of 1464581 Heading H1N To prevent lateral rocking of the moving contacts of an electric switch comprising a pair of fixed contacts and a contact bridge supporting moving contacts, a flat resilient plate 38 is fixed to the operating member 30 of the switch by a bolt 37 so as to be over the moving contact bridge and engage with and bear on specially formed arcuate portions 32 of this bridge when the contacts are closed, the resilient plate engaging the contact bridge along parallel lines transverse to the length of the contact bridge. Pins 39 in the contact bridge pass through apertures in the flat plate to increase the stability of the arrangement. To prevent separation of the fixed and moving contacts when short circuit current flows through them a pair of co-operating ferromagnetic members are associated with each pair of contacts, the arrangement being such that each pair of ferromagnetic members 42, 46 encircles its associated contacts so that when short circuit current flows the attraction between the members, in addition to any contact biasing spring effect, prevents the separation of the contacts, such an arrangement being disclosed in Specification 1,464,581.
