Jeff said if ANYONE finds a better switch that fits the diamater of the Chucks, he will be happy to make the change. Problem is, finding one that meets our wants is near impossible bc of its shape and size. Jeff made a few Chucks with like 100 switches, about 5 in each tube to show us what they looked like and we all agreed the switch he is using is best until someone finds a better option.
If you DO find one that works - be sure to post it here and PM/Email Jeff with the manufactures name and info and Im positive he will look into it!
