“The AAA battery holder with switch is fantastic, apart from saving batteries, it means you don't have to unplug the batteries, every time you connecting or disconnecting things to the pins.”
“Works fine with the Badger 2040. It's a little heavy to wear with the Badger on a lanyard but putting some strong magnets on it to attach as a backing to the badge through clothing may work - like a nametag without the pin.”
