When the pressure in the system goes high of a set value, the switch opens and breaks the electrical circuit to the targeted loads such as compressors or burners. A high-pressure switch helps protect your system from potential damage due to high pressure by constantly checking pressure and stopping operation if pressure increases beyond the safe level.
