Q258 Allows any pressure switch that meets the pneumatic rules.

Q459 Allows switches to be callibrated per manufacturer-provided instructions. It does not allow the end user to adjust a switch that the manufacturer did not intend to be adjustable.

R88 calls out the requirements for the pressure switch. The adjust-ability of the switch is not specified.

R88
The pressure switch requirements are:

• It must be connected to the high-pressure side of the pneumatic circuit (i.e. prior to the pressure regulator) to sense the “stored” pressure of the circuit.
• The two wires from the pressure switch must be connected directly to a digital input and ground pin on the Digital Sidecar.
• The cRIO must be programmed to sense the state of the switch and operate the relay module that powers the compressor to prevent over-pressuring the system.

Doing a quick control-F search on the game manual, the only time the word Nason showed up was in the word Panasonic when referencing allowable batteries. When searching Q&A only 258 and 459 mention the word Nason. Where does the phrase "must be the same or equivilant to the Nason pressure switch." come from. I can't seem to find it.

I heard there was an inspector who successfully got adjustable pressure switches removed from a robot at Champs. Clearly it was not a universal interpretation amongst inspectors, as we ran with this.
