There are a million switches for the 395 on Ebay for around $25.00.I'd try there first. Just put the part number in the Ebay search.Hope that helps.Good luck.
The armature has a front and rear bearing.The rear bearing has a rubber boot around which is a bearing damper.Often you will get a break in the field and the tool will just stop working. What you might check is the brushes.They should move freely in and out of the brush tubes.Look very closley at the brush tube that the brushes ride in and see if you can see any distortion or signs of melted plastic around the tube.The dremel tools don't deal will with heat and if you pushed the tool alittle too hard it will be damaged by excessive heat.Hope that helps.Good luck.
The model 275 has the the same armature as a model 395. Which means the shaft is the same size and thread. It's my thought that the 2615297355 is a match.
This coupling is for the Dremel 395. Is this the Dremel model number of the the tool you need the coupling for.
Dimensions are ID (Shaft) 6mm,, OD 19mm, Width 6mm.
I am after information myself as to how to remove the shaft extension to allow the front bearing replacement.
Just remove them from the armature and take them to a local bearing supply in your area. They should have them in stock, if not the can order them in.
The schematics shown for the various 395's don't illustrate the part but name a "coupling" part number 2615 2943 09 (figure 818) $1.61. I think this is what I need but is not available.
Is there anyway to get this "coupling"? My tool is otherwise in perfect working condition.
The part number for the Dremel coupling is 2615294309.
Hope this helps,
