Abstract

1332582 Magnetically actuated switches URANYA SpA 21 July 1971 [9 Nov 1970] 34123/71 Heading H1N In a magnetically operated, sealed switch suitable for use in the circuit of a lamp for lighting the interior of a refrigerator, automobile &c., when the door is opened, a bridging contact 4, Fig. 2, is arranged to close the circuit through terminal contacts 3 under the action of a permanent magnet 5 mounted in the switch casing behind a partition 7. A. magnetic doorclosure strip 10, or another magnet specifically provided, draws the contact 4 away from the fixed contacts 3 when the door is closed. The ends of the contact 4 may be guided by balls or rollers 9 and the fixed contact 3 may comprise adjustable screws.
