Compressor to Pressure Switch

[Mr. 1033]

Hey Teams,

Just a quick and silly question for you.

My team built the Andy Mark pneumatic set up that can be found at the following website:
http://www.andymark.com/product-p/am-2000.htm

The picture shows a 4 way union where the pressure switch is mounted.

My rules team member showed us the picture from the game manual where it says that the system must look like their example circuit. In the circuit they have the pressure switch mount later in the system.

It makes sense that the switch is after the tanks to me but I could be wrong.

Haven't used pneumatics in almost 5 years so we're a little rusty.

Thanks,

1033
