A liquid contact switch for use in switching matrixes of the cross-bar actuated type comprises a block of insulating material with two sets of holes in a plurality of parallel planes at right angles to each other containing a fluidconducting medium such as mercury and intersected by a piston having slots also containing fluid conducting medium whereby movement of the piston makes an electrical connection via the fluid medium in the slots. In one example a selected pair of holes 2, 3, Fig. 24, are interconnected by piston 11 caused to slide by an electromagnetically actuated cross-bar system. in the example (shown) the piston 10 is rotated by a cross-bar system whereby fluid medium in slots 11 bridges between the bores 2, 3. A number of examples of electromagnetically actuated mechanically latched cross-bar systems are described. In one example the selected sliding notched piston 10, Fig. 8, is depressed by solenoid actuation of cross-bar 26 having tappets 31 engageable with a pin 80 moved under a selected tappet 31 by solenoid actuated slides 75 which return under action of springs 32 to lock the selected piston 10 down by engagement of block 78 under key-hole slot 83. In another example the piston 10, Fig. 14, is rotated through 180 degrees in two stages; the cross-bar 90 being actuated first to bring cam slot 96 opposite projection 89 on the piston 10. Cross-bar 91 is then actuated whereby slot 98, 100 rotates projection 89 through 90 degrees, to enter cam slot 96. The piston projection 89 is then rotated through a further 90 degrees by action of return spring 94 when cross-bar 90 is released. In Fig. 26 (not shown), the mercury is sealed in the bores 23 by insulating plugs (51) inserted at each end. Conductor wires (52) are threaded through the plugs (51) and looped externally.
