9V Battery and Switch Holder

thingiverse

I wanted a 9V holder with a switch, but I didn't want one with dangling connectors. The wires always seem to break internally, and I also didn't want a small switch that was hard to find by feel if the battery was behind something. I got the 9V battery holder from Amazon at https://www.amazon.com/gp/product/B07Q1N2MHT/. I had some small rocker switches left over from another project at https://www.amazon.com/gp/product/B07MV3PX6K. Because the switch is SPDT and only one side needs to function, I connected a jumper between both sides so that either of them will work as a two-position SPST switch. The jumper is shown in an inset picture above. I ran the wires through (red) or out the switch hole (black), so they could be soldered to the switch. Then, I ran the switch wire through the hole and pressed the switch into place. The black holder can be connected to the box via double stick Gorilla Glue-brand clear tape, Velcro, etc., as long as it's at least 3mm thick. Alternatively, you can use the three screw/nail holes to attach it to the surface of the printed box. In this case, I installed the box in a 1970s Daiichi pachinko ball machine so that it would be self-contained and not need a wall adapter or other battery placed elsewhere in the frame.
