HHF - With
pushbutton switches, use NO (normally open) switches. With momentary
toggles, you can use either OFF-(MOM) or ON-(MOM), since the momentary side is all you will be using.
As far as those Shack switches go, they're not the best quality. (Plus, they're not double pole...read on.

)
Sokol1 - I have to disagree with your 2nd drawing....Sorry.
You have basically shorted all your yellow, red, blue, and green wires together. If you look at the trace (above D4), it connects the left switch's black wire with the lower switch's black wire. With your wiring, either position of the left, or the bottom, switches will short all 4 of them out.
The better solution would be to use double pole switches, in the corners.
Or, you can use all double poles, if you want them all to look the same at the panel. (The 4 main switches would just use one set of the poles.)
