Combat robots and other creations will appreciate this Screw Power Switch designed for their needs. It's optimized to work seamlessly with 4/40 bolts and matching square nuts. When assembled, including a hot glue bond, wires, and mounting screws, this switch comes in at an impressive 3.6 grams total weight. A key consideration during the design process was the tendency of solder to have difficulty adhering to the nuts. To address this challenge, a unique solution was implemented: square nuts are used instead. By drilling a precise 1/16th inch hole into each corner of the nut, a 24 gauge wire can then be threaded through the hole and soldered in place. This ingenious approach ensures that the wire remains securely attached, eliminating any risk of it backing out or breaking off.
