YM30 series Pressure switch

The YM30 employs a differential pressure to actuate a precision micro switch at a chosen pressure setting. This may be the difference between atmospheric and a negative or positive pressure or between any two given pressures. When a change of pressure occurs between the negative pressure chamber and the positive pressure chamber, the main diaphragm activates the micro switch at a pre-determ value.
