Professional English Translation of NY30 Series Pressure Switch Specifications‌

Operating Principle‌

The NY3O series pressure switch utilizes an integrated bellows and mechanical linkage system. When system pressure increases/decreases, the corresponding adjustment spring and corrugated steel generate expansion/contraction displacement, actuating the switch via lever mechanism to open/close the control circuit.
