The circuit connections are equivalent to those which are obtainable with the G.P.O. Telephone for Granular Transmitter, "C", i.e., the signalling apparatus joined to Terminals 1 and 5 is entirely disconnected from the line leads when the Micro Telephone is lifted.
Similar to the Telephone No. 20 except that the bell is replaced by an exposed contact.
