Hi, I posted some prototype of stand alone pipe switch few month back. Made of off-the-shelf aluminium pill tube and PVC pipe connector with no soldering. The switch is still using EPM V2. I did not really complete the outer wooden pipe using that switch but i think it should work. Here're the links if you're interested.
