YN50S00040D1 SWITCH

Product Overview

The YN50S00040D1 Switch is a genuine electrical component engineered for Kobelco SK200-8, SK210LC-8, SK330-8, and SK350LC-8 excavators. This switch is used in the machine’s control console for selecting working modes, activating auxiliary functions, or operating other electrical circuits within the cab.

The Kobelco SK200-8 and SK210LC-8 are 20-21 ton class excavators, while the SK330-8 and SK350LC-8 are 33-35 ton class large excavators . These machines feature sophisticated electrical systems that control various functions through cab-mounted switches, providing operators with convenient control over working modes, lighting, auxiliary attachments, and other systems.

The YN50S00040D1 is part of Kobelco’s YN50S series of electrical switches. This series also includes the YN50S00026F1, YN50S00026F2, and YN50S00026F3 ignition switches used in SK200-8 excavators . The switch is typically mounted on the control panel or right-hand console for easy operator access.

When the switch fails due to internal contact wear, corrosion, or mechanical damage, the affected function may become inoperable or intermittent. Replacing a faulty switch with this YN50S00040D1 component restores proper electrical control to the operator console.
