Magneto Wall Switchboards

N660A3 shown pictured to the right.

n660a3.jpg (10086 bytes)Designed to give full operating facilities and constructed to occupy small space, these switch-boards are particularly suitable where a high-grade magneto installation is desired.

The woodwork is matt polished and the metal parts are finished in durable black.

Equipped with line indicators and jacks, clearing indicators, speaking and ringing keys and a "ring back" key to ring on the answering cords should it be necessary, also night bell, switch, generator and micro-telephone so that these switchboards are complete and do not require a separate telephone for the operator.

The case is standardised for all equipment's, dummies being fitted in the spaces of partially equipped boards.

All boards are wired for the full capacity of 30 lines and 6 cord circuits so that those having part equipment's can be considerably and readily extended as required.

The layout of a fully equipped front panel from the top is:-
three rows of 10 indicators, N4815D; spacing strip; clearing indicators, N4815D; speaking, ringing and alarm keys; spacing strip; three rows of 10 jacks with numbered labels; and a spacing strip.
