Coin Cell Battery Holder – 2 x CR2032 (Enclosed)
This is a simple coin cell battery holder that can enclose two CR2032 batteries inside itself, and safely kept closed via two phillips head screws. Each battery holder will run batteries in series, output up to 6V, and is equipped with an On/Off slide switch and two 6″ power wires (one positive and one negative) on the back.
