Record

The Record Electrical Co. Ltd.
Broadheath
Altrincham
Cheshire
UK


The firm displayed a working model of a portion of a town lighting system to demonstrate the Record Remote Operated Selective Switching Units. Two different systems were shown: (a) selectivity through a pilot wire and (b) selectivity by interruption of the main circuit. Both seems could be operated from a central point, either manually or by time-switch. Eight combinations of signal were available. - APLE Conference Programme Glasgow 1945
