I have an Echo SRM-300AE which has been a helpful beast up until this year. I inherited it so I'm not sure how old it is or how well it has been maintained. When I took it down from winter storage I noticed the stop switch is broken. I've tried rigging on a new toggle switch, but noticed the original only had one terminal on it. I've tried a couple different parts sites but most of the parts for this unit are discontinued. Anyone have an idea if it is possible to use a modern two-terminal toggle switch somehow? I found one on eBay but it is crazy expensive (plus shipping).
