OK rant over.....just been down stairs and connected the 24V DC PSU up to the limit switches (2 only) I wired them so that the neutrals all went to a common din rail terminal, the signal from the first went to the +ve of the second and I measured from the neutral to the signal of the second with my multimeter. It lit both lights of the sensors and when any sensor was activated the 24V DC went to zero which was a result....far better playing with things than thinking about them on paper or screen!!!
That looks better but be aware that you are wiring switches in series which contery to popular belief does work with Prox switches but just be aware that reaction time drops the more you have but it's not a problem with only 4 switches.
