SWITCH, FLOAT (P/N l15h-59) - As Removed, Serviceable

The l15h-59 is a float-operated liquid level switch for aircraft fuel and fluid tanks. This electromechanical switch detects liquid presence in tank sumps and signals annunciators or control logic when levels reach preset thresholds. Commonly installed in Bombardier Learjet 55 and Learjet 60 fuel management systems, the float mechanism rises and falls with fluid level changes, triggering electrical contacts for low-level warnings or automatic shutoff functions.

Installation requires verification against the aircraft maintenance manual and Illustrated Parts Catalog specifications.
