Looking for plans for a RCA input switching box

Biggest problem is dust. My open to the world won't work most of the time due to dust. If you find a good sealed(completely sealed) are the only one that works.
By sealed I mean no openings to the atmosphere of any type. including unused RCA connectors.

I have one of Steve’s ZSBs and it is a great little box. Mine is modified with a stepped attenuator and a mono switch so it is basically a passive pre. It has lots of uses.

If all you want is a couple more inputs then a project box, six RCA jacks, and a DPDT toggle switch are all you need for the big stuff.

wouldn't that actually only give you one more input by the time you plug in the box?
