Abstract

600,872. Mercury switches. RADIO APPARAT CO. AKTIESELSKABET H. EBBESEN & I. C. JENSEN, and GRUE, O. E. Oct. 17, 1945, No. 27218. Convention date, Dec. 6, 1943. [Class 38 (v)] In a thermally-operated mercury interrupter wherein a mercury column 14 oscillates in two branches 10, 12 of a closed gas-filled tube to make contact from the supply 22 to a load circuit at 26 and at contact 20 to energize its operating heater 16, the mercury column is arranged so that when the heater is switched off after operation, it will occupy a position as shown, whereby any gas which has leaked through the column from branch 10 to branch 12 and which would ultimately render the device inoperative, will bubble back again to balance the pressure.
