I've recently started building electronic circuits and figured I'll just build a pedal guitar. Well I've made a few pedals, but I've put together some other electronics and have more planned, and I didn't want to use 3pdt switches in my other non-guitar pedal projects. These switches meet my needs. I've only used a few spst switches, but I have upcoming projects that will use dpdt switches and I'm sure they will meet my needs for those projects.
