yo, bridge the switch out by running a wire from one side of the switch to the other.
why do you want to make it case positive?
You need a case negative build because the 660nm red diodes are case negative.
All linear drivers will do.
I mean the LPC-826 red diode is case negative. It could be the diode in the penlaser is different.
Have you attached the battery (-) to the spring and the battery (+) to the brass case of the module and pressed the switch?
