A Joey bed is a tray in the basement that is used for storage and slides in and out, some manually and some electrically.
Keith, I think the 3 way switch you are talking about is one that will operate a motor or electrical fixture from two different positions. They have to be wired correctly and in the 120 volt world, both switches have to be 3 way switches. That doesn't mean 3 position switch which is " Forward, Off, Reverse". I am sure BCS or RV Outfitters can help you and most electricians. I know that if you don't know what you are doing, you are going to cause yourself problems and I can't help you, as I only know what they are and not how to install a 3 way, 3 position switch.
