Abstract

Abstract A miniature circuit board disconnect socket in which the inner legs of a M-shaped spring contact are confined within a socket body with the connecting bight portion therebetween adjacent the closed end of the body and the outer legs of the spring contact extending along the exterior of the socket body. The miniature socket is soldered to a circuit board to establish a direct electrical connection between circuitry on the board and the portion of the spring within the socket body. A solder resist may be applied to the spring adjacent the open end of the socket body to prevent molten solder from wicking into the socket during soldering.
