Patent ID: 8628342

Claim:
A device comprising: (a) a bottom portion providing at least a first external electrical contact point below the bottom portion and a second external electrical contact point provided by an outer surface of the bottom portion, an inner surface of the bottom portion being electrically conductive with the outer surface; (b) a bottom pressure pin, within the bottom portion, electrically connected to the first contact point; (c) a top portion rotatably fixed to the bottom portion, the top portion comprising a first electrical connector and a second electrical connector, wherein the first and second connectors are functionally exposed through the top portion; (d) a printed circuit board (PCB), within the bottom portion, providing a first connection route in electrical connection with the first electrical connector and a second connection route in electrical connection with the second electrical connector, wherein the PCB is fixably attached to the first and second electrical connectors and wherein the first connection route is in continuous electrical contact with the bottom pressure pin; and (e) a radial pressure pin fixably connected to the PCB's second connection route, the radial pressure pin providing continuous electrical connection with the second contact point through the bottom portion's inner surface.
