The pressure switch that comes in the KOP is set for about 115-120 psi. There is a pressure regulator that you need to use to reduce this to a working pressure of 60 psi or less. And there is another regulator you can use to reduce it further for other purposes.

If you want to limit the high pressure storage part of the system to 60 psi, you'll probably need to get a pressure switch or transducer that is set to 60 psi, or a transducer that can measure the pressure. But you'll probably find out that you really just need to understand the pneumatic system fully, and that you don't need to bother with extra switches.
