Abstract

963,453. Mercury and other conducting liquid switches. ELECTRO CONTROLS Inc. July 27, 1960 [Sept. 3, 1959], No. 26174/60. Heading H2B. The time delay of a mercury or other conducting liquid switch is varied by an adjustable restriction in the plastics tube. As shown, the switch comprises an endless tube having limbs 22, 24, 26, 28 pivoted horizontally. An adjustable valve 44 in limb 28 provides a time delay for the liquid when the switch is tilted clockwise by rod 48, bridging between two fixed contacts at the junction of limbs 24, 26 occurring only when all the liquid has flowed to the junction. Tilting anti-clockwise causes rapid breaking and the liquid flows via limb 26 to the junction of limbs 22, 28. The switch may be modified, as a double throw switch, by providing a valve in limb 26, and contacts at the junction of limbs 22, 28. In Fig. 6 (not shown), the valve is replaced by a flexible tube whose area is adjusted by a clamp.
