I haven't looked at the code but it could also consider 11 as >7 and assign 111 to the mask, it probably doesn't but you should still use a valid entry and understand how the bit masking works  ;D

I set 3 as you suggested. I didn't invent 11, I found it on a discussion, a wrong discussion ...
I solved the switch problem , I hope.
twisted wires and rc filters did not work.
I mounted a good shielded cable and works great, even without gnd on the shield.
now I have other problem:
the laser dot (or laser rectangle) is double
any suggestions?
my english is very bad, please be patient. :)

This is often an indication of the diode failing but may also be something simple like the lens isn't flat (parallel to the diode) or needs cleaning.

I disassembled the laser, I cleaned the lens but no change of the laser beam.
then I removed the lens again and cleaned the diode. now it works perfectly.
I don't understand how the diode got dirty and not the lens; the magic of Chinese things :)

I cannot tell a lie. I put that spot of dirt on your lens just to test your persistence. Not going to tell you what I did to the ball bearings.
