AAA Battery Box with Switch
Description
I needed a AAA battery box with a switch so I could put it in a plaque and LED lite-up a hollow 3D printed temple. For this project you need the following: - If doing the same thing as me, LED's - Battery Contacts - Two pieces of wire (18 to 24 gauge, solid, not stranded ... I just use wires from Cat6) - 2x M3 8mm long screws - 2x M3 10mm self tapping screws - 2x AAA batteries Most of these parts you can find cheap on eBay in bulk. A "Assembly Instructions.txt" file is included for directions, but below are those same instructions: 1. Print Parts 2. Slide battery contacts into their slots (may need a pair of pliers to get them in, it can be tight) - Note there is one side of the box where the battery wire contacts leave the box, and the other side the battery contacts touch each other. - The side where the contacts touch each other, it's easiest if you slide them into each other then slide them into their slot. - Note the contacts are arranged so the batteries will be inserted in opposite directions from each other, this increases the voltage to 3v which is what the LEDs need. 3. Super glue (Krazy glue) the switch into the box (be careful to not get any glue in the switch mechanism), and wait for it to dry completely. 4. Attach Wires - Attach a wire to the battery contact not by the switch. - Cut off a small piece of wire and attach the battery contact next to the switch, and the switch terminal closest to the battery contact together. - Attach the other wire to the middle terminal of the switch (make sure it does not touch the terminal wired to the battery contact). - If you have a soldering iron and some solder, it would be good to solder your connection, it will make them much more reliable (better contact) and less likely to move and touch each other. 5. Attach the bottom plate (slide it into place). - This plate goes on the side you slide the contacts into from. After this is on, the contacts wont be able to come out. - Super glue the bottom plate on, so it doesn't come apart and wait for it to dry. 6. Attach the wires to the LEDs. - Note LEDs are polarized, so positive and negative must be connected to the correct sides. - It may be helpful to throw in some batteries and flip the switch to on and test in order to correctly align the LEDs. 7. Close up the box. - Insert batteries (if not already done). - Use the 2 M3 8mm screws to screw on the battery cover 8. Mount on a plaque. - Cut a hole the size of the box (obviously not including the mounting tab area). - Slide the box in with the switch and battery cover facing the bottom side of the plaque and use the 2 M3 10mm self tapping screws to attach the box to the plaque. - Mount the hollow display item that's meant to light up on the top of the plaque covering the box.
