In addition paragraph 4 of Section 4, "In addition, another intent of these rules is to have all energy sources and active actuation systems on the ROBOT (e.g. batteries, compressors, motors, servos, cylinders, and their controllers) drawn from a well-defined set of options. This is to ensure that all Teams have access to the same actuation resources, and to ensure that the Inspectors are able to accurately assess the legality of a given part."
For those reasons, adjustable pressure switches are deemed illegal, in particular any switch that can be set to a pressure higher than 115 psi. Throughout section 4.10 the Nason Pressure switch is shown as the pressure switch. BTW, I am betting that the OP is using a standard robot pressure gauge that may or may not be accurate. Tapping on several (hundred) over the years have caused them to change pressure displayed.

I wish the rules and manual's language would be a lot clearer.
I am reading same paragraph and I do not see that it means prohibition of pressure switches other than Nason switch provided in KOP
