Description
The Amana-Goodman 0130F00508 Dual Air Pressure Switch is a safety and control accessory within HVAC System applications intended to measure and control airflow pressure within the furnace or air handler. For purposes of ensuring that the switch is functional in providing a safety feature and to ensure that reactor is operational the switch contains a feature of pressure variation. In other words it is a pressure differential sensor. The “dual” feature of this switch is that it is two switches in one switch, each set to activate at two different pressures.
