thingiverse
This device serves as a custom key for shutting down power supply. It seamlessly fits into standard 2.1mm charging ports, such as those found on https://www.thecustomsabershop.com/Switchcraft-21mm-Power-Jack-P822.aspx. Unlike traditional keys that require removal to cut power, this specialized turn-key allows users to toggle the battery connection to their electronics in real-time without needing to physically remove it.
