Interface and fabrication method for lighting and other electrical devices

A light bulb comprising:

• a cavity-defining housing arranged between a contact-defining end and a light-transmitting end, and a male base proximate to the contact-defining end;
• a printed circuit board (PCB) at least partially disposed within the housing, wherein the PCB includes a first electrically conductive edge contact arranged on or proximate to a bottom edge of the PCB, and the PCB includes a second electrically conductive edge contact arranged on or proximate to a lateral edge of the PCB, with at least one boundary of the first electrically conductive edge contact being arranged closer than at least one boundary of the second electrically conductive edge contact to the contact-defining end, and with the at least one boundary of the second electrically conductive edge contact being arranged closer than the at least one boundary of the first electrically conductive edge contact to the light-transmitting end;
• an externally accessible electrically conductive foot contact arranged at the contact-defining end;
• an externally accessible electrically conductive lateral contact arranged on or along a lateral surface of the male base;
• and
• a compressive electrical interface arranged between the foot contact and the first electrically conductive edge contact, wherein the compressive electrical interface is arranged to provide conductive electrical communication between the foot contact and the first electrically conductive edge contact;
• wherein the second electrically conductive edge contact extends through an aperture defined in the housing to define the lateral contact, with the second electrically conductive edge contact being externally accessible along the lateral surface of the male base.

A method for fabricating a light bulb, the method comprising inserting, into a housing, a printed circuit board (PCB) including a first electrically conductive edge contact arranged on or protruding from a transverse edge of the PCB and including a second electrically conductive edge contact arranged on or protruding from a longitudinal edge of the PCB, with at least one boundary of the second electrically conductive edge contact being arranged closer than at least one boundary of the first electrically conductive edge contact to a light-transmitting end of the light bulb that opposes a contact-defining end of the light bulb;

• wherein said insertion causes the first electrically conductive edge contact to engage an externally accessible electrically conductive foot contact retained by an electrically insulating portion of the housing, with a first compressive electrical interface arranged between the foot contact and the first electrically conductive edge contact, to provide conductive electrical communication between the foot contact and the first electrically conductive edge contact;
• and
• wherein said insertion causes the second electrically conductive edge contact to engage an externally accessible electrically conductive lateral contact associated with the housing, with a second compressive electrical interface arranged between the lateral contact and the second electrically conductive edge contact, to provide conductive electrical communication between the lateral contact and the second electrically conductive edge contact.
