Figure 4-35.  Lever and Pressure Operated Control Heads

Pressure operated switches must be connected to the pilot piping or discharge manifolds as 

shown in Figure 4-36 and Figure 4-37. The preferred mounting position is upright. Both the 

standard and explosion-proof pressure switches have 1/2-inch NPT pressure inlets to connect 

to the piping. The electrical connections are either 1/2-inch conduit knockouts or 1-inch NPT 

fittings. The minimum operating pressure required is 50 PSI.
