Abstract

197,486. Coventry Automatic Telephones, Ltd., (Adams, A. H.). March 28, 1922. Automatic exchange selectors.-The spacers A between the rows of terminals C are made of soft metal, preferably corrugated or indented aluminium, separated from the terminals by thin flexible hard insulating-material B, such as fish paper, which projects beyond the spacers. The bank is compressed to such an extent that the spacers are deformed so as to grip the flat-wire terminals and prevent their lateral movement. Reference is made to previous proposals, in which the spacers are of rigid insulating-material, or of sheet insulating-material interleaved with metal spacers, or of pulpy or compressible insulating-material, the terminals having embossed projections, or of hard metal insulated from the terminals by thin paper.
