Lenco help needed

I am running a CS-2 lenco, shifting it with 250 psi co2 and I need to find a pressure switch for CO2 that will close as soon as you apply pressure to it,

anyone know were to get one at ?

thanks again

Pressure switches off the shelf or have one made to a specific pressure you want

 

we use one from NOS safety fuel pressure (adjustable)

 

This is what I use:
