I need a replacement switch assembly (part # 2610925722) for my model 300 dremel rotary tool.

Burnt out brushes.

Dremel has on their homepage an accessory fast finder.

I am sure you can get closer information by searching their fast finder.

Good Luck

Something similiar with a belt sander on / off switch that had dirt inbetween the contacts in the switch. After cleaning the switch contacts it worked.

Well, yes you can measure the switch, look for continuity. I suspect something else is wrong, some models had armature issues. Measure the coils and armature for continuity.

hello. yes. go to dremel.com and get new brushes for your tool.
ps kindly rate my answer as helpful. thank you. Joe

there is no fuse in this tool, you have another problem and I would go to Dremel.com and talk to their tech support and also download a breakdown for this tool.

You have an open spot in the switch. You will need to replace the variable speed switch. The part number is 2610925722 and the manual for the tool says it is $14.00. (Though this may have changed since the manual was printed) Unfortunately the switch is unavailable according to Bosch. You may be able to pick one up on ebay. Good Luck.
