Abstract
Abstract A connecting block in which a support member has a large number of terminal clips extending through the member, for connection of wires to both ends, the support member pivotally mounted in a housing so that one or other side of the support member, and related ends of terminal clips, can be selectively presented for wiring. A hinged cover attached to the support member can be utilized to retain the support member in one selected position, the support member normally positioned in the other position, as by gravity.
