Dremel, since purchased by Bosch, has discontinued producing some on/off replacement switches for some Dremel rotary tools manufactured over 25 years ago.
Kauffman Family Tool had 2 NOS switches in stock and emailed images of both to confirm their correct application. From where I'm sitting no other online company carried this particular rare switch.
Kauffman Family Tool runs an essential business the way most American companies used to operate long before computer algorithms changed the business model and eliminated the emphasis on customer service.
Suffering the humiliation of dealing with a dehumanizing monolith like Amazon is no longer required. Kauffman Family Tool Repair now has that power and it's doubtful Amazon will ever come close.

Smooth, error-free purchase. Parts arrived sooner than expected and fit and work perfectly. Couldn't be more pleased with the service and prices. Will be coming back the next time I need a part!

The collar/clamp assembly failed on my Porter Cable reciprocating saw. Imagine my disgust to find that the clamp and retaining pin kit is no longer offered by the manufacturer. How many thousands of good saws will be rendered useless by this move? Fortunately, I came across Kauffman's website and found they still had stock of the needed parts. Ordered on a Thursday, had the parts on Monday. Even received a followup email to make sure the parts had arrived safely. Outstanding service from people you can trust. Will definitely turn to Kauffman for my future parts needs. Thank you!!!
