    as Clive said
    wire N/C switches in series

    it should be the safer option as the machine will stop if a wire breaks
    as this is more likely than a two core cable being short circuited
    (although it could happen if a cable is crushed)

    the last diagram of post 11 is for 1 axis ,
    you will need three pairs of N/C switches for the 3 axis

    as mach 3 only homes 1 axis at a time you could connect all 6 switches in series and use just 1 input
