Abstract

The invention relates to a matrix switching device (1) having a plurality of contact devices placed at selected crossings between rows and columns, and each contact device includes at least one mobile contact element (2a). The device further includes a plurality of first rods (2) reciprocally mobile, related to rows, a plurality of reciprocally movable second bars (4, 4 '), related to columns, a plurality of electric insulation balls (2h , 2g) each of which is assigned to a selected junction and can be moved in response to the movement of one or both bars (3, 4). Two mutually adjacent balls (2g, 2h) are provided at each selected junction. A first ball (2g) has a larger diameter than a second ball (2h) and the first ball has a dimension such that when it moves it causes the mobile contact element (2a) to move in one direction, and the second ball ( 2h) has dimensions such that it has no effect on the movable contact independently of said movement. The second ball (2h) is adapted to provide movement to said first ball (2)

The second bar 4 can be discharged upwards and downwards by means of a solenoid 10 and the bar 4 'can be driven "in a similar manner by means of a solepoid 10'. Accordingly, the first bar 3 can be moved forward and backward by corresponding solenoids, indicated in Figure 1 but not described in detail. The pattern of movement of the balls 2g, 2h will be described more clearly with reference to figure 13, which illustrates the displacement of the bars 3 and 4 where the position A has the purpose of illustrating an initial position »according to the figures 4 and 11. In the position B, all the small bolts Í2h) in a column are displaced upwards in the figure by means of a rod 4 of actuator related to column, where the balls 2g and 2h are located immediately to »adjacent between them and in relation to rows. In the position C, a small ball and a large ball 2 »j, 2h (oriented per row) have been slightly displaced to the left by a bar 3» of accianaclor oriented per row. In the position D, a large ball 2g has been displaced downwards by a rod 4 of the accusator related to the column and influenced by the contact at the intersection and the contact device 2 is in the position of in Figure 5. The illustrated "i spiosi 11 V" D switching consists > of sheets, boards or plates adapted for the manufacture of printed circuit boards. The boards 5, 6, 7, 9 and the boards 5 ', 6' and 9 'may conveniently have a thickness of 0.5 mm, while the boards 8 and 8' will suitably have a thickness of 0. 8 mm. If the boards 9 and 9 'are provided with printed circuits in both the: DS 1 9a, 9b and 9a', 9b '), the ladders: r > -r. 9a and 9a 'can be used to carry board components, even when this increases the thickness > Of the device. It will be understood that the invention is not limited to the above-described and illustrated exemplary embodiment of said invention and what modifications can be made within the scope of the concept of the present invention as defined in the appended claims.
