An application of the Halbach Array, by witch, groups of Magnets, each set 90 degrees to the next, have almost all the magnetic attraction concentrated on one side, i.e. a Monopole Magnet. In this case, the top Magnets, by the lever on the back, turn 180 degrees, so as to either attract or repell the sliding bottom array, thus creating a switchable magnet array, out of permanent Magnets. The magnets are hot glued to the respective Lego parts, either the gears, or the bottom plate. Remember to glue the Magnets BEFORE setting them to the Mechanism...
