RELAY (P/N 65126-21) - New Surplus

The 65126-21 is an aviation relay that switches high-current electrical loads using low-current control signals in 14/28 VDC aircraft systems. This component handles starter-contactor control circuits and distribution switching where direct pilot control would require impractically large switches. The relay amplifies low-power signals from cockpit controls into high-power output for engine starters, landing gear motors, and other critical systems.

Installation requires mounting per aircraft wiring diagrams with appropriate circuit protection and wire gauging. Function-check procedures follow the applicable aircraft maintenance manual and FAA AC 43.13-1B guidance.
