SwitchPort

thingiverse

This is a switched power port that snaps onto a 3/8" hardwood dowel. I printed it on a raft because the parts are relatively small and there are some details that need to be accurately printed on the mating surfaces (pins and holes). In fact, there are quite a few details that should be addressed: these mostly have to do with the hardware and wiring. First of all, the socket (5.5 x 2.1mm female connector) needs to be wired before it's connected to the "SwitchPort" AND the hexagonal retainer nut need to be installed first. In one of the pictures it shows a large fastener that was used to seat the hex nut into a groove at the bottom of the SwitchPort body. It just occurred to me that 3/8" dowel would probably work as well. Anyway, the socket needs to be soldered to the incoming wire on the (red) negative pole and a short 25mm (black) jumper soldered to the positive pole (that's the short one). Since the switch enters the "SwitchBody from the bottom and is retained in that body with the "SwitchNut", the soldering can be done easily. It is suggested that you verify the proper functioning of your electrical connections before you mate the two halves. I tried taking one of these apart and the pins broke off.... so it's sort of a one shot deal. Get it right the first time. The other issue worth mentioning is the nut that retains the switch is not internally threaded. It is sized so that when installed it will be threaded. Try to get this installed without cross threading or the part will break along the layer lines. The wire is 28 AWG. The switch is MTS-101 2 Position Mini Toggle Switch 2 Pin SPST and the socket is DC Power Supply Jack Socket Female Panel Mount Connector 5.5 x 2.1mm, all of which came from eBay. The wire can be routed either up or down.
