Grizzly T26674 Button Repair

Over the last few months I’ve noticed the buttons on my dust remote starting to flake out.  Some days they would require a few clicks to work, other days they would be fine.  Well today the on button totally died.

Because the buttons were getting more and more unreliable over time I had a pretty solid hunch that the culprit were the actual buttons on the remote’s printed circuit board.  So I took it apart, and the on switch when pressed by itself sounded different, less “clicky”.

So I removed both the on and timer down switches and then soldered the timer switch in the on switch’s old home.

So on the board you can see the four switch positions S1 – S4:

  • S1: On button
  • S2: Off button
  • S3: Timer down
  • S4: Timer up

I just moved S3 to S1.  And lo and behold my dust collector now turned on with its usual roar!  And amusingly enough that was exact moment the off switch decided to crap out, I had to unplug the whole works.  So I did the same operation with S4 and S2 and fixed that too.

I’m going to replace the timer switches so that I can resell this remote, but it works fine without the timer buttons in place.  On eBay or Amazon just look for 6mm x 6mm x 4.5mm through-hole momemtary switches, they’ll be about $1.25 per 100 shipped from China.  I did some googling for “high quality” switches but really didn’t find anything obvious; but perhaps these more expensive switches from Jameco would be more durable?  Or they might just cost more.

This repair would work for the Grizzly T26673 as well because it would use the same cheap components.

If you are interested in doing this easy repair yourself here’s what you’ll need:

  • Soldering iron
  • Solder, something thin like 0.5mm or 0.6mm diameter
  • Some means to remove the old solder from the switch pins.  “Desoldering wick” will work in a pinch but I’ve always had good luck with a desoldering iron like this one.
