Abstract

1536968 Magnetic switches FELTEN & GUILLEAUME 19 Nov 1976 [2 Dec 1975] 48429/76 Heading H1N A holding electromagnet similar to that of Specification 1,232,725 has its parallel spaced laminations 4, 5 formed with sideways projecting aligned feet 4a, 5a respectively which act as pole members for engagement by complete effective surface area of the permanent magnet 1. The magnet is held by arm 11 in a recess in a spring member 8 having projections 10 engaged over the feet 4a, 5a and an extension 9 on which the electromagnet armature is rockable.
