Federal Signal Switch Box Mystery (to me, anyway)

[CatBacker88]

Can anyone tell me what these switch boxes are for? Can't find anything about them on Federal's reference pages. I swiped these pics off eBay, but I have two identical units I came up with a couple of years ago and I'm not too proud to ask for some help here!

So, it's fair to say in my case they are good for nothing?

You could rewire it for another use. The SW400SS circuit diagram will give you a guide: https://www.fedsig.com/resource-document/file/7638
