- Page 2 Pressure Switches Principle The SOR Adjustable Dead Band pressure switch incorporates two industry proven Static “O” Ring pressure sensing elements. Media pressure on the areas of the pistons counteracts the forces of the range springs — each adjustable by a separate adjusting nut — and moves the piston shafts to operate the lever assembly which, in turn, actuates and deactuates the electrical switching element.
