This post is old so this might be a moot point, but in case anyone else finds it and can benefit, I used a pot switch on mine too... I added a marked up photo on my post here (http://www.thebitterbrewer.com/viewtopic.php?f=1&t=64#p185) to illustrate the wiring to the pot switch.
Hi all, checking in here from Norwalk, CT... (grew up in Tolland too!)... I've been brewing in Norwalk for about three years now... just finished building my new brewstand, photos here: TheBitterBrewer.com • View topic - My Single Tier Brew Stand Build
