The wide range of types and resistances of our relays makes
it impracticable to catalogue them all here . The following views
are shown to convey an idea of the types generally used . The
resistances of the windings and the arrangements of contacts are
varied to meet the requirements of the circuits in which they aro
placed.
No . 44 Type Is self-restoring . Has a line operating coil and a
restoring coil . Used when a local signal circuit is to be oper
ated by ringing on the line . When the line coil is energized,
the front armature is released and falls forward, closing a local
contact . When the restoring coil is energized, the front armature
is restored to the vertical position . Makes one contact
when operated .
No . 87 Type Closes a local circuit only while the line is being rung
upon . Has flexible contact springs and a heavy armature
sluggish action so that the local circuit remains closed as long
as there is ringing current on the line . Used in trunk circuits
between central offices . Has a cross-talk proof cover . Makes
one contact when operated .
No. 89 Type Has an operating coil and a locking coil . Made to
respond to ringing current and to close a circuit through its
armature contact and locking coil so that the relay remains
in the operated position after ringing has ceased . Used for
toll line signalling and in toll cord supervisory circuits . Has
cross-talk proof cover . Makes one contact when operated .
