Laser Switch

This switch lets you have control over whether or not the lasers are turned on, which can be handy if you're doing testing.

Mount the switch in the acrylic sheet using the mounting hole.

Solder the wire from the lasers' power connection to the middle connection on the switch.

Cut, splice and tin a piece of wire that is approximately 89 mm in length.

Solder the 89 mm long piece of wire to the top connection on the switch. The other end of the wire will eventually connect to the FeatherWing Doubler's 3.3V signal.
