Hi All,
I want to wire up 4 aspect signals not using a rotary switch under DC, but preferably using a DPDT switch and 'reading ahead' to the next signal. For example - the switch will just give an 'ON' or 'OFF' for the signal, when 'OFF' the aspect will be dependent as to what the next signal is showing - if it's red then this signal would be single yellow, if the next signal is single yellow this signal would be double yellow etc.
I saw a pretty good wiring diagram for 3 aspect signalling, but I haven't seen anything for 4 aspects, and I'm not proficient enough to adapt the 3 aspect wiring!
I hope one of you clever guys out there can help me, and please, keep it as simple as possible!
Thanks all.
