Abstract

1,098,378. Magnetic switches. B. & R. RELAYS Ltd. Oct. 27, 1966 [Oct. 27. 1965], No. 45558/65. Heading H2B. A push-button operated sealed magnetic reed contact unit 11, having a bayonet fitting end cap 11f on an insulated casing 11d, fits in a projecting flange 10c of a support 10. The push-button 13 passes through a further flange 10b of the support and over the end of the contact unit remote from its bayonet fixing in the flange 10c. The button body 13a abuts a cylindrical axially-magnetized permanent magnet which is biased to the position shown by a compression spring 13c. Movement of the magnet by the push-button operates change-over or normally open contacts connected to terminals 11b, 11h the latter also retaining the caps 11f and 11e of the contact unit. A spring-biased lever may latch the pushbutton so that the contacts remain operated until the button is again pressed (Figs. 3 and 4, not shown).
