Makita Switch

My LS 1211 is acting a bit cranky, like releasing the handle switch doesn't kill the power i.e. the saw stays on. Not a good situation. Anyone have this issue and what did you do?
Suspect it's time to open up the handle assembly and blow it out, but wanted to ask here first.

Clean it out.

I agree with Larry. And if you can get to the contacts, clean them very gently with some really fine sandpaper. Nothing to lose. Can't bread something that is already broken.

Still "sticks".
Looks like I go fish for a new switch for a 20 year old saw.

I've "refurbished" a lot of equipment switches over the years. Most just require cleaning but if sticking I disassemble completely and lubricate all the moving parts. Examine the mechanical mechanism for signs of wear or a broken part and repair as needed. Some require drilling out rivets to get apart.
After cleaning the contacts (1500 grit paper is good, don't remove any plating) I apply a tiny smear of dielectric grease to each contact surface. Depending on the switch I might lube the moving parts with dry lube or silicon grease. After testing, if the switch is subject to gumming up with fine dust (like the Jet 1642 switch) I seal the outside from dust with plastic wrap, tape, sealer, whatever fits best.
You forgot to say what a LS 1211 is but since it is in a handle is a clue. If the switch is a microswitch engaged by a trigger mechanism, replacements are readily available. Even a non-standard microswitch can usually be replaced with one off the shelf with some mounting ingenuity as long as the current rating is ok. The mfgr may even have an inexpensive direct replacement. But if the microswitch itself checks out a non-release problem is probably wear in the trigger, levers or ratchets that engage the switch. Hard to say without inspection.

Sliding compound miter saw. Levers and such are fine. Switch is a micro unit that I'll just replace. $20 ain't worth the time to fuss with it.

>>> $20 ain't worth the time to fuss with it.
I agree. The switches I've fixed were mostly difficult or expensive to obtain or it was Saturday and I or a friend needed/wanted it NOW or the problem was obvious and easy.
