Abstract
499,393. Electromagnetic mercury switches. CIANCHI, A. July 28, 1937, No. 20917/36. [Class 38 (v)] An electromagnetically operated mercury switch comprises a sealed envelope 1 having electrodes 6 which are electrically connected by mercury when a plunger 3 is drawn down by the action on an armature 4 of a solenoid 5 surrounding the switch vessel 1. The solenoid is enclosed in a magnetic casing 7 having an air gap 8 and insulating end caps 10 enclosed in metal caps 11 having cable outlets 13. The switch vessel is cushioned by pads 17 of sponge rubber. In a modification, all the electrical connections are brought to one end cap which is provided with projecting pins for engagement with contact sockets.
