The tumble down, releasing trains on positioning cues, can be done a number of ways, a twist on old anti collision and stop & go automation wiring, but as a brand it seems a convenient "stackable" automation choice.... if I recall right.
My thought right now is why a board... For mounting? or is not electrical you mean but a panel?
You need to know the max switch volt/amp/watt rating. Mini's can be very light, especially if it is board mount as sensitive logic use is more common there. I guess it comes down to the number of led controlled by one switch. Led don't draw much alone but it can add up quick.
