Side switch EDC that does NOT need locked out.

Firelight2, Thanks for the detailed walk through. I wish I would see this when I tried to take mine out the first time. Going to give this a shot for sure.

After tearing down my D4 several times I managed to break the membrane switch. Got it half way stuck back together. Now it will only turn on if pressed with thumbnail in the perfect spot.

Ordered a replacement. But now I have some time to come up with a better solution.

A thicker bezel would be ideal, but I am no machinist.
I cut the nub off the switch boot, I think that was working somewhat.
I modded the UI to allow e-lockout momentary to memorized level.
The DW3R1 will be my EDC. Or ELSE.

Firelight2 filed down a nickel plated brass #14 finishing washer and he also did a cover

And these aluminium colored countersunk washers are interesting:

My Wuben E05 has not turned on in my pocket, switch needs a firm push to activate, my favorite.
