That's not correct. The A/B switch shown will pass DC power just fine until it doesn't. That's the problem with that kind of a switch, they simply are not terribly reliable. I still like the Radio Shack High Isolation A/B switch as I have many, many successful installations without a single failure. However, there are likely many good high quality A/B switches out there. I have seen too many sliders fail so while many might work I would never recommend one for any installation.
YMMV
