Abstract

Abstract A multiple contact connector having a low profile has a bottom member for attachment to a large circuit board, the bottom member having a plurality of spaced parallel spring cantilever contact members. A top member is attached to an edge of another circuit board, for example a smaller board, the top member having a plurality of spaced parallel contact members having top and bottom legs, the top legs of the contact members making contact with the smaller board circuit pattern and the bottom legs contacting the cantilever contact members of the bottom member. A spring member extends up from the bottom member and snaps over the top member.
