Aqara Xiaomi Wireless Mini Switch Necklace Pendant Adapter

thingiverse

Turn the Aqara mini switch into a multi-purpose necklace pendant. I personally use it as a life-alert type device for my grandpa that doubles as a garage door opener. Use the stock adhesive ring to attach the adapter. Hole is 4mm so it comfortably fits most chains through it. I use 3mm elastic cord which can be bought here: https://www.amazon.com/Usew-8-Inch-Stretch-String-Elastic/dp/B00Z63H6E4/ Simply cut and superglue the ends together, add some extra glue once it dries for a better bond. Also included is a gasket which can be printed in TPU to seal the battery compartment and make it less likely to accidentally pop open since the adapter is mounted to the cover. Print this with .05 or .07mm layer height. The switch is easy to waterproof by popping it open and coating the board in a conformal coating of your choice. I used MG Chemicals silicone conformal coating on most of the PCB and a light spray of CorrosionX HD for the buttons and battery terminals.
