How To: New Wire-5 project (Bergeron)

[Chris Suslowicz]

(One practical demonstration of Boob's Law[1] later...)

Switchboard UC 6 line with battery and Box, Accessory, Switchboard UC 6-line containing 7 pulley weights and cords; operator's Telephone, Hand, No.2; Night Bell and connector. Weight 35 lb. 6 oz.

The current for the switchboard is provided by a battery of three cells (Cells, Dry, X, Mk.II; or Cells, Dry, Inert S, Mk.I) contained in a removable box behind the line units in the back of the case, connections being made to the battery box by means of plugs and cords. Terminals are provided on the line terminal panel at the back of the switchboard for the connection of an external battery if desired.

(Pulley weights are apparently optional for the 6-line version.)

The battery box has sockets on the end to take the two plugs from the switchboard.

Best regards,
Chris.

[1] You always find something the last place you look - I think I found manuals for everything between the pre-WW2 "Mark 236" and the postwar 40/160 Line Exchange before the Switchboards UC 10-line and 6-line pamphlet turned up!
