This switchboard is designed to occupy small space, and although it stands on the floor it should be installed where it can be fastened to the wall or to supports from the wall.

The woodwork is matt polished and the external metal fittings finished in black and copper bronze.

The extension indicators are the totally enclosed self-restoring type which cannot be tampered with by the operator, and the circuit is so arranged that these indicators also give positive supervision.

The exchange lines are fitted with the hand-restored drop indicators which are robust and not readily put out of order.

"Bell" receiver resting on switch-hook, solid back transmitter on adjustable arm, alarm which operates when any indicator is actuated, and night switching keys so that the exchange lines may be put through at night to any of the extension telephones.

NOTE :- Supplied also for working to automatic systems.

This switchboard can be supplied partially equipped, but wired for the full capacity.
