ABSTRACT:
A solvent soluble plastic form (104) is molded around a spring-type battery contact (102) such that one end (102A) of the battery contact projects from the form. A one-piece injection molded thermoplastic housing (202) is then molded around the battery contact and form, thereby molding the end of the battery contact into the housing. The soluble plastic form is then dissolved in an appropriate solvent, leaving a housing with a cavity (202D) that contains the battery contact.
