Software-Controlled Switches (SoftConfig)
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. 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, note the default setting for reference designators
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.
