Switch assembly Adjusting screw Working principle When the MR units OUT side pressure is applied to piston q, piston q moves until it balances with the force of pressure adjustment spring w. The movement of piston q is detected by switch assembly e and outputs ON and OFF signals. The set pressure can be adjusted by turning adjustment screw r, which adjusts the spring force.
