Thx for the confirmation.

. It is not clear why you need a second switch. Any pressure change at one certain point in the system will be felt almost immediately by the entire system. Thanks for the reply. I'll conclude that on the high side it doesn't matter if it is in the vapor or liquid section. If that is not correct pl...

Where can a trinary switch be placed in a TXV AC circuit? (This application is a 80-91 VW Vanagon and my question is general?
