Bruce,

 

Does this replace = the existing switch? Screws in and you set your desired pressure on the bod= y of the sensor ?

Or does it need another component to work lik= e a converter or relay ?

 

If it just screws in= can it also out put the actual pressure to say a Grand Rapids  EFIS ?= ?? for example ?

Sev= eral of our guys (including me) have junked our mechanical pressure switche= s and moved to solid state adjustable switches.
