Just a basic extender for a standard toggle switch. The switch boots on the right are just a standard purchased boot and are not apart of the drawing. I quick drew up in Inventor, a 2" long 0.500" O.D. (at the top) and 0.375" O.D. (at the base) and a 0.238" I.D. 0.750" deep. I printed in black PLA and to install I heated the print up with a heat gun to slide it on the switch lever. It holds very nicely. The O.D. of my switch lever was 0.241". Hope it adds some length to your switch! It was originally designed to extend my toggle switch higher than the others in my stack to control a snow plow on my tractor. It makes it easier to operate with gloves on!
