Antweight Screw Switch

This is a substitute for the fingertech screw switch for antweights. This works for both US and UK antweights. Just solder wires onto the edge of two m3 nuts, push them in place, and screw the m3*6 bolt in. This switch also supports an LED (blue, 5mm) that can be dropped in and glued in place with hot glue in the front. Use a 10k resistor for the LED so that it doesn't burn out (varies if you are not using blue and 7.4v). The switch can be dropped in a 12mm square hole with 2mm chamfers.
