Simplified Switch Installation Drawing: Correct Configuration - GE Masoneilan SVI II ESD Installation And Maintenance Manual

When the switch is on (closed) the external voltage must be dropped across the load
(Figure 74).
Load is designed to ensure that voltage across the switch is < 1 V.
Figure 74 Simplified Switch Installation Drawing: Correct Configuration
Without a load, when the switch is on (closed) the external voltage would be dropped across
the switch. This damages the switch (Figure 75).
