Abstract

1277848 Temperature responsive switches RANCO CONTROLS Ltd 19 April 1971 [16 April 1970] 18314/70 Heading H1N Two independent switches 13, 14 are conjointly operated by a single temperature responsive actuating element 6 by means of an open rectangular frame 10 which slides in its own plane. The frame slides in grooves in a housing (Fig. 1, not shown) to which an expansible tube 7 is fixed. A non-expansible rod 8 connects the free end of tube 7 to the frame and individual adjusting screws 17, 18 couple the frame 10 to the switches 13, 14. The adjusting screws have individual temperature indicators 24. Alternatively, Fig. 5, the screws 17, 18 are preset and a common indicating knob 128 adjusts the frame 10 in relation to rod 108.
