MAGNETO TABLE PATTERN
Intrinsically safe magneto telephone
This instrument is an advance on previous table pattern magneto telephones, being lighter and more compact. This is made possible by the use of a generator with an “Alnico” magnet system which is smaller and lighter than its predecessors, yet is equally efficient. The internal apparatus comprises an induction coil, generator, 2000 ohm ringer, switch spring-set and cord connecting block. Space is provided for a capacitor when required. The whole of the apparatus is mounted on a metal base plate which can be detached complete from the case.
