This part is very important in the provision of adequate air flow and overall system performance. Used under a pressure range of -0.38 inches of water column (-0.38”WC), the switch functions as a simple on/off switch activated by slight changes in pressure. When the negative pressure is at or below -0.38”WC, the switch is triggered to close and make an electrical connection.
