My lathe has 2 sets of cycle start and feed hold buttons, one on each side of the door. First pic.
My new mill has only one set of buttons, and they are in a spot I don't like, way over by the e-stop. Plus they are the cheapo plastic taiwan variety button which I hate.
I want to add a second pair of nice round stainless frame buttons on the lower left of the control, just below the panel. Second pic. I want to put them just below the mode switch so I don't have to look at the damn control every time I need to hit the start button.
Question is- do I need something to isolate the pairs, or can I just splice the new buttons in parallel? I think they are NO, will the open circuit on the other button prevent the circuit from closing if they are wired parallel? I don't want to disable the buttons on the panel- just want to add another set in a more convenient spot.
