mechanically interlocked, preventing
more than one source from being simulta-
neously selected. This prevents sources
from being shorted together, an undesir-
able condition when dealing with tele-
phone lines!
A destination can also be set to have
no source selected. With a little practice
an operator can easily learn to set all of
the source switches to the off (out) posi-
tion. By momentarily “tapping” on any
switch that’s in its off (out) position, any
other switch that is the on (in) position
will be reset to its off (out) position.
It’s important to understand that each of
the six source signals can be selected to
route to none, any, or all five of the desti-
nations; there are no “lockout” or “priority”
arrangements. As an example, if source 1
is selected for both destinations A and D,
the telephone line (or lines) associated
with source 1 will be connected to both
destinations A and D. While this arrange-
ment is flexible, it does require an operator
to be careful when assigning a single
source to multiple destinations.
