Another Digital Calliper Battery Saver

Most of these callipers tend to drain batteries when not in use, I'm forever replacing the batteries even if I havent used it since the last time! Saw a few designs of a battery saver that essentially disconnects the battery but all the designs I could find were for different types/brands so I designed this one for mine.... may help others too. Been working great for me the past few months since designing it, push it in to disconnect the battery and pull it out a little to connect the battery.
