Figure 3-4: Example of a Bus Switch
The following figure shows the equivalent circuit to the Example of Bus Switch figure but utilizes mechanical
switches. Notice the default for reference designators
SWC
and
SWD
is illustrated by black boxes located closer to the
ON label of the switches to enable the number signals by default. Also notice the default setting for reference desig-
nators
SWE
and
SWF
is OFF. In order to connect the letters instead of the numbers, the user physically changes all
switches on
SWC
and
SWD
to the OFF position and all switches on
SWE
and
SEF
to the ON position.
