MAGNETO SWITCHBOARDS
Floor Pattern
No. 2400 SERIES
 

In this series of magneto switchboards the indicators and jacks in the extension line circuits are of the combined type.  The indicator is automatically restored by the insertion of the answering plug into the associated line jack, thereby simplifying the work of the operator and increasing the rate at which connections can be established.

The frameworks are of solid walnut and are made in three sizes to accommodate equipment for 50, 100 and 150 lines respectively.  Lift-out rear panels are provided to give easy access to the apparatus, wiring and line terminals.  Cord circuits are of the usual type, employing combined ringing and speaking keys, and space is available for the addition of up to 15 transfer jacks for use when several switchboards are lined up together to form a large exchange.

The operator's telephone consists of a breastplate transmitter and head receiver complete with cords and plug. Alternatively, a hand combination set can be supplied if specially ordered.  Ringing current is supplied from a 4-magnet hand generator.

An alarm bell, operated by contacts on the drop indicators, is fitted inside the switchboard and can be disconnected by a key when desired.

Any of the magneto telephones of the bridging or bridging sure-ring types listed in this catalogue are suitable for use as extension instruments with No. 2400 series switchboards.

Cat. No. 2481 is show pictured above.
