Patent: Magnetic light switch with hermetic glass box

Abstract
The construction of the invention is composed of a hermetically sealed cylindric glass box filled with inert gas, a broad U-shaped permanent magnet on it: two pairs of galvanized, impermanently magnetizable steel pieces inside the glass box, on its brim, with electric wires brought from one pair of pieces, electrodes, to an outside source of electric current: an impermanently magnetizable galvanized steel bar inside the glass box, turned on and off between the steel pieces by the U-magnet: a hand lever turning the U-magnet: and a housing box, in which the magnetic light switch has been installed. The hermetic glass box can be made using the technics of electric bulbs. There is no burning and consuming dirt and dust inside the glass box, and inert gas inside the box prevents sparking from burning metal surfaces and generating ozone and nitrogen oxides, too. The invention is applicable to other purposes, too, e.g. to master and idividual switches of electric systems and devices. Safety can be increased with two bimetallic triggers inside the glass box cutting the electric current, if the device is heating too much.
