N2020H
Magneto table telephone with one magnet generator


A one-piece table instrument is at all times preferable to one made up of two or more parts, and the magneto type of telephone has been the most difficult to combine in a neat form.

Hitherto telephones for magneto working have been heavy and cumbersome on account of the size of the generators available. With modern magnetic materials a new and highly efficient magneto generator of very small size and weight has been produced. By incorporating this new generator into our already popular moulded case an instrument of excellent symmetry, light and efficient, is provided for magneto working.

The internal apparatus is mounted on a metal base plate which can be completely detached from the case. The apparatus comprises, induction coil, generator, 1000 ohm ringer and gongs, switch springset and cord connecting block, space being also provided for a condenser when required.

The telephone comprises of:-
Micro-telephone N5852, Micro-cord N4021, Inset N7750, Mouthpiece N8634, Receiver N6815, Earpiece N4443, Receiver Diaphragm N4400, Generator handle N55577 and Terminal Block Cord N4324.

The sliding tray fitment is not practicable on this telephone.

Dimensions - 9.25 x 8 x 6
Weight - 7.5lbs
