Abstract

1,187,446. Vacuum switches. GENERAL ELECTRIC CO. 26 June, 1967 [5 Aug., 1966], No. 29320/67. Heading H1N. A vacuum switch has its contacts 13, 14 biased into the closed position by differential pressure acting on a bellows 12 against the bias of a spring 33. The contacts are positively coupled to a member 16 which has a lost-motion connection 18 to an actuating member 17. Should the differential pressure fall due to partial loss of vacuum in the switch envelope, the lost motion connection permits the spring 33 to move the member 16 to open the contacts 13, 14. The movement of the member 16 also releases latching balls 43 which free a cap 40 for upward movement under the bias of a spring 41. The cap operates a switch 50 to close contacts 52 in an alarm circuit and to open contacts 54 in circuit with the drive motor 22 for an operating cam 19.
