Abstract

1,129,357. Magnetic switches. GENERAL ELECTRIC CO. 15 Aug., 1966 [7 Oct., 1965], No. 36429/66. Heading H1N. To reduce contact bounce the movable reed assembly of a sealed contact unit is forked to provide two overlapping magnetic reeds 21, 24 which rub together when the assembly engages a fixed contact member e.g., 11 or 12. The reeds 21, 24 have substantially the same natural frequency and reed 24 is welded to reed 21 so that it lies substantially tangential thereto when the reed 21 engages the fixed contact member 11. A bias magnet 16 is mounted on contact member 11 either externally of the tube 10 as shown or internally thereof. Instead of a double throw unit a single throw unit may be provided. A coil or permanent magnet may operate the unit.
