harbor freight switch adaptor

thingiverse

If your like me, you have a bunch of Harbor Freight free little flashlights sitting around. Well I like the switches on the bottom. When the light goes poof I save them. Well I made a switch adapter so I could use them on other projects. I tried threading them, but with little success, so I finally came up with a size for it that lets you screw the switch in, kind of cutting the threads as you go. 1- Print part (I used PLA) 2- Cut two wires to whatever length you want. (I used 18 gauge) 3- Strip them and bend them as in the picture. The top one is split into a T shape The bottom one is bent into a circle to fit in the middle. On this one I soldered the loop to be sure the spring on the switch would connect. On the top one I found that leaving it unsoldered is best because it needs to compact. 3- Push wires through the holes from the center out. 4-Assemble the switch, being careful to start the threads straight. (I put the assembly gently into a wood vice to keep it parallel) using pliers started the first threads. WALA! You've got an on off switch for almost any low voltage project.
