ABSTRACT:
A battery receptacle has first and second types of electrical contacts received in guide slots formed in facing end wall surfaces of a housing. The first type of electrical contact has a inwardly facing protrusion extending inwardly of the compartment a distance sufficient to be engaged by the positive electrical contact of a battery but less than the distance required to make contact with the negative electrical contact of the battery. The second type of electrical contact is a tapered spring contact with the wide end positioned inwardly of the receptacle, the diameter of the wide end being larger than the diameter of the positive contact of a battery. With batteries correctly installed, the first type of contact engages the positive contact of the battery and the second type of contact engages the negative contact of the battery. In any other configuration, at least one of the electrical contacts is not engaged with a battery contact. A movable partition positioned within the receptacle partially divides the compartment in two longitudinally to assist in guiding installation of each battery and to accommodate batteries of different lengths.
