 Siebe duct pressure switch  for hvac control. High quality. Made in Canada. It is in perfect working order and has been tested. It was removed from a Carel humidifier unit. This switch senses duct pressure when the duct is active through a 1/4 inch reference tube that attaches to the switch's diaphragm's barbed connector. The diaphragm has a barb on both sides for extra versatility. It will switch on either with a vacuum pressure present in the duct or a positive pressure present in the duct. In the case of the humidifier it was controlling, the switch was turning the humidifier on when the Air conditioner was cooling by sensing the AC duct pressure. Switch works with 24 volt circuits.
