Abstract
884,397. Magnetic switches. MAGNAVOX CO. April 9, 1958 [April 15, 1957], No. 11690/61. Divided out of 884,396. Class 38 (5). A magnetically-operated switch comprises a non-magnetic metal tube 58 fitted with a soft iron plug 64 carrying a resilient wire support 62 for the armature 60. The latter has a contact 60a alternatively engaging fixed contacts 68, 70 supported in insulating compound 72 in the upper portion 66 of the tube 58. Portion 66 carries a terminal 74 for the electrical connection to the armature contact. The contacts 60a, 68 and 70 may be of gold and the tube may be fluid filled for preventing armature vibration.
