March 22. Switches. - Relates to a mercury switch described in connexion with a railway and operated by a vehicle passing along the line. Fig. 1 shows a sectional elevation of one form of the switch, which is pivoted at b and consists of a vessel a divided into two compartments ...
Mercury, a silvery liquid, is one of the most familiar of elements. As a metal that forms compounds easily when combined with other elements, mercury is used in scientific instruments like thermometers and barometers, in electrical switches and even in dental fillings. Despite its many uses, mer...
Mercury is a toxic, volatile metal that is used in electrical switches, relays, and motion detectors because of its electrical conductivity, low volatilit... RF Kovar 被引量: 0发表: 2006年 On the ball: mercury-free tilt switches often employ interesting ball designs.(SWITCHES & RELAYS) Mercu...
The faint light given off by mercury when shaken in the vacuum within a barometer seemed similar enough that it became known as the “mercurial phosphor” that likely inspired Hauksbee’s electrical experiments, which when coupled with a vacuum apparatus nearly led to the invention of the ...
The good electrical conductivity of mercury makes it exceptionally useful in sealed electrical switches and relays. An electricaldischargethrough mercury vapour contained in a fused silica tube or bulb produces a bluish glow rich inultraviolet light, a phenomenon exploited in ultraviolet, fluorescent, and...

It is used in electrical switches and rectifiers because of its high electrical conductivity, and as catalysts in the chemical industry [1]. It easily forms alloys (or amalgams) with other metals like silver, tin, zinc, and gold [1, 2]. The amalgams were previously used for extracting go...

electrical contact. However, to avoid mercury shorting of the stationary contacts and the common contact, the material which insulates them from one another should be non-mercury wettable. Glass has been found to be an insulator which is suitable for this purpose. Mercury relay switches of this...
