  • Previous posts about the spring being the positive power connection are wrong. The spring is negative and the aluminum housing and/or the laser lead connected to the pad indicated by the black Magic Marker marks on the aluminum housing is positive.

    Jump the pads along either edge of the push button switch for continuous ON.

No public wish lists :(
