Abstract

849,851. Mercury switches. GOODRICH CO., B. F. May 7, 1958 [May, 9, 1957], No. 14641/58. Class 38 (5). [Also in Group XXXIII] A switch for controlling the de-icing heaters of an aerofoil has a heat-conducting plate 20 arranged to be mounted in contact with the inner surface of the aerofoil. The plate 20 may be curved, as shown, or may be flat, and has an integral tubular part 21 projecting into a space 22 at one end of an insulating housing 12 to which the plate is sealed around its edge. A mercury thermometer 23 is arranged partly in the tube 21 and extending through a bore 18 in the housing where it is held by a rubber cushion 26, held in place by a removable cover 19. The switch has external lugs, Fig. 4 (not shown), which are engaged by springs to urge the switch against the aerofoil. Specification 725,125 is referred to.
