Im wiring a system with a photosensor,timer and light stack. I connected all the commons(neg) DC connections toghther and Im using the positive connections for the switching lead in the Senor, for thr lead that turns the coil on in the timer and for thr lead that will switch on the light stack.
Is it better to use the positive leads for this app. vs switching everythinng with the common lead.
System is all 24VDC.
