A battery receptor, or housing, capable of reversing its polarity to render operative an inserted battery regardless of the orientation of the inserted battery, which includes first and a second receptor electrical contacts and a polarity-reversing assembly which can bring about the reversal of the polarity of the contacts based on the difference in the physical configuration of the two ends of the inserted battery. Specifically, the battery receptor includes an electrically conductive retainer member which is rigidly connected to the receptor and which is in electrical contact with one of the receptor contacts. The retainer member is sized and shaped so as to retain the large diameter end of the battery but not the small diameter protrusion at the other end of the battery which is able to project through the plane of the retainer member and activate a switch which controls the polarity of the contacts.
