The levers ??^, n of the signalling keysare each made in two metal parts insulated from one another. In the po&ition of rest, the distributorof the station S sends into the line a series of alternating currents, which traverse the relay at S,and also that at S, where they flow to earth by the levers I and the contacts T of the keys Aj and both stations the armature A and B of the relays oscillate, but have no action on theirrecorders. When the key A^ at station S, Fig. 1123, is alone depressed, the armatures A at both stations stopvibrating, and the corresponding recorders signal. Similarly when Bj is depressed t
