Abstract:
Magnetic light switch with hermetic glass box, comprising:a hermetically sealed cylindrical glass box, made by the same technics as electric bulbs, being installed in a housing box in a hole on a wall; the said glass box being filled with inert gas; a broad U-shaped permanent magnet being placed on the glass box, so that it can be turned with a hand lever clockwise and counterclockwise; two pairs of galvanized, impermanently magnetizable, sharp-cornered steel pieces being attached with some hard fixing agent inside the said glass box, on its brim, at right angles to each others; two electric pins being fixed in one pair of said pieces, called electrodes, pressed into little holes in the said electrodes, protruding outside the said glass box, on the back side of it; the said electric pins, the device being assembled, being pressed into the holes in one pair of connectors with a pair of electric wires to an outside source of electric current; an impermanently magnetizable, rectangular, shaped like a prism, galvanized steel bar being placed inside the said glass box, so that the said steel bar can be turned between the said steel pieces; the said steel bar being turned by the said hand lever onto the said electrodes, so that the electric current is on, and to the opposite direction, so that the current is off; the said U-magnet, said steel bar and one pair of the said steel pieces consisting a magnet circuit, creating clicking on- and off-function to lessen sparking; the said glass box being installed in its housing box using a rubber or other elastic ring; the said housing box being made of some hard and strong dielectric material and closed with a lid of same as the said housing or other suitable material, using proper fastening; the axis of the said hand lever being pressed through a sliding-contact bearing in the center of the said lid and into a hole in the center of the U-magnet, the said axis being fixed on its halfly cut end with a lock spring or by other means; the said whole device being fixed on a wall with 2 to 4 fixing screws, or by other means; burning and consuming dirt and dust being prevented from getting inside the said glass box and consuming the metal surfaces by sealing the box with some hard agent when assembling the box, and protruding the said two electric pins out of it, and inert gas inside the said glass box preventing sparking from burning said dirt and dust as well as the metal surfaces inside the said glass box; galvanizing of said parts inside the said glass box being of good conducting metal and thick enough to endure on- and off-function of the said switch; the said magnetic switch being applicable to light switches, as well as to master switches of electric systems and individual switches of electric devices, by changing its size and other criterions according to the amperage and voltage used.
