I couldn't find a good place for this in the general Internet, so I thought I'd share it with you folks first.
Craftsman and B&D sold a 20v power tool system with interchangeable attachments (drill, saws, etc.) called BoltOn and Matrix respectively. I've used this ever since I got it, and just used it to help build my forge, but yesterday it broke and I was heartbroken.
Instead of running out and buying a whole new tool system, I happened upon a great solution!
The problem was the switch in the handle. Since this model is very much discontinued, I couldn't find replacements easily. Ended up taking a chance and bought the current B&D 20v drill and took the thing apart. The electronics are basically the same, and with a little basic soldering, I was able to completely replace the electrical system in the faulty handle with the new drill's electric components. Worked like a charm!
$50 for the new drill, but now I've got an extra battery and a spare motor! Used replacement handles for this system are on eBay for around $100. An brand new set of 20v power tools would've been several hundreds of dollars, so I think I'm doing okay!
Couldn't find a good site to simply replace the switch...maybe someone here has a resource they can share?
I don't know how many others might be BoltOn or Matrix owners, or appreciate the system the way I do, but for those of you who do, maybe this could help in that horrible moment when your favorite or only tools die.
Anyways, hope this helps someone out there!
