LOW PRESSURE SWITCH (P/N 1-1224-bu) - New Surplus

The 1-1224-bu is a low pressure switch that monitors fluid or pneumatic system pressure and triggers an electrical signal when pressure drops below a set threshold. It uses a diaphragm or bellows element to sense pressure changes and actuate internal contacts reliably. Commonly installed in engine oil pressure warning circuits to activate cockpit annunciators or initiate protective shutdown logic.

Installation requires positioning per the aircraft maintenance manual with proper set point adjustment and electrical wiring per applicable schematics. Used across general and commercial aviation platforms.
