Abstract

1,060,238. Reed armature relays. GENERAL REED CO. Nov. 13, 1964 [Dec. 11, 1963], No. 46313/64. Heading H2B. To reduce inter-electrode capacitance in a magnetic reed switch, a sealed tube 12 contains a relatively short rigid magnetic reed 20, a second magnetic reed 28 having a reduced portion 26 to render it flexible and a third magnetic reed 34 which is rigid and inclined at an acute angle with respect to the second reed and has an arcuate contact portion 36. The upper surface of reed 28 and the lower surface of reed 20 are convex (Fig. 3, not shown), and reed 28 may be pre-tensioned into normal engagement with the reed 34, as shown, or may lie midway between reeds 20 and 34 to form a centre-stable relay. The arcuate end of reed 36 produces a high contact pressure with a smooth wiping action and its angular aspect to reed 28 concentrates the magnetic flux at the ends to give a more efficient switching action with reduced contact bounce.
