A panel-mounting battery holder for PP3 9V batteries having a removeable drawer in which the PP3 is placed making battery changing very quick & simple. When the drawer is closed the battery contacts are made. These connections are brought out to solder tags at the rear. The compartment body is designed to be mounted in a rectangular hole in a panel & fixed with two countersunk M3 screws & the drawer is keyed to prevent accidental reverse polarity.
