Now I know why my 4T switch keeps clicking all of the way around! I need to find that washer I threw in my parts bin and install it! It thought I was just buying crappy switches. Thanks!That's pretty much how I found out about it. I had the washers and nut off a 4P3T, and the darn thing just kept turning and turning, clicking and clicking, and I'm thinking "When the heck did I order a 4P12T switch!!?"
