One New Aftermarket Replacement Swing and Boom Oil Pressure Switch for Komatsu Excavators, Bulldozers, and Crushers

This hydraulic oil pressure switch monitors swing and boom circuit pressure in Komatsu excavators and related equipment.

A failed or faulty pressure switch can disrupt hydraulic function and cause operational downtime.
