MAGNETIC KEYBOARD Russian patent published in 2019 - IPC G06F3/23 H01H1/54 H01H36/00 

FIELD: data input devices.

SUBSTANCE: invention relates to the input devices. Technical result is achieved by the fact that magnetic keyboard includes a housing consisting of 4 layers, 1 layer contains fixed magnetic elements, 2 layer consists of layer with contact pads, 3 layer contains movable magnetic elements in working chambers, coated with current-conducting coating and facing similar poles to magnetic elements in 1 layer, located from each other at distance of magnetic repulsive forces, 4 layer contains buttons with magnetic elements facing similar poles to magnetic elements in 3 layer, located from each other at distance of magnetic repulsive forces, wherein 1, 2 and 3 layers are tightly connected to each other; as magnetic elements neodymium magnets are used; by changing distance between magnetic elements it is possible to change length of keys stroke; with change of distance between magnetic elements it can be specified moment of closing to final point of button or in final point of button.

EFFECT: creation of a keyboard of a thin, reliable and durable structure with a wide range of adjustment of length of a stroke of a key till the moment of closing of contacts and protection of contacts from moisture, dust and increased wear.
