Not exactly sure what you're describing. But I'll say this: Power routing switches were great back in the old analog DC days because they fed power to spurs or other situations. After a loco passed the points, the points could then be reversed leaving said loco without power so it wouldn't move. This too saved the need for an on/off toggle for that particular piece of track.. Today, there is little need for power routing switches due to the independence of DCC locos..each moving or stopping anywhere. I don't know anything about Kato switches. But if their switches have this turnable screw to change them from 'power-routing' to 'all-live' and assuming you are in DCC, by all means make them all-live...Only thing remaining is to make sure there are no hidden polarity-reversing loops. Wyes, turntables, balloon tracks are reverse loops.. Those still need DPDT toggles or gadgets such as HexFrogJuicers..
Others may differ with my comments. One good thing I will say about power-routing switches: When wired/gapped correctly they have less stallout potential than all-live due to not having an insulated frog which all-live must have, in turn making the frog a potential stall out place, especially for locos with short wheel bases. Hope this helps. M
