I built an eub with a double 9v battery box and an on off on switch. I hate 9 v batteries and the dangers of having one die at a show so it's kind of like a back up fuel tank, only using one battery at a time. So I've snapped the toggle off of the switch twice now and want to change it for a slider. If someone could point me toward one, I'd be grateful. I dug around on mouser.com for a while and I am overwhelmed with the large selection. Something that's easily mounted on an aluminum plate. I have only this picture, the switch is on the right.
