Abstract
Abstract Coordinates selection switch which comprises two groups of rectangular metal crossbars, each group being formed of parallel bars and the groups lying in interlaced equidistant levels. The crossbars are contained in a moulded plastics block and hermetically sealed cylindrical channels extend through the block and the cross-bars at the intersections thereof. Pistons made of magnetic material and having metal rings are disposed in the channels. Two groups of displaceable and rectangular operating bars are disposed on each side of the block and magnets are inserted into these operating bars at the same spacing from one another as the channels. The outside surface of the piston rings and the crossbar edges which appear in the channels are wetted by mercury for providing good contacts.

Claim 1
Independent Claim
201 words
A coordinates selection switch comprising two groups of crossed conductive metal bars, one said group comprising parallel bars which extend in a given direction and which are disposed in planes at given evenly distributed levels, the other group comprising parallel bars which extend at right-angles to said given direction and which are disposed at evenly distributed levels between said given levels, a moulded insulating plastics block receiving said crossed bars, cylindrical channels in checkerwork pattern extending through said block and said crossed bars at the intersections thereof, pistons made of magnetic material, having metal rings and disposed in said channels, means for hermetically closing said channels, two groups of displaceable operating bars, the first group being in the form of bars providing operation in a given direction which are disposed on one side of said block and the second group in the form of bars providing operation in a direction perpendicular to said given direction which are disposed on the other side of said block, magnets inserted into said operating bars at the same spacing from one another as the channels, the outside surface of said piston rings and said crossed-bar edges which appear in said channels being wetted by mercury.
Claim 2
