Description

The Komatsu TY9878 is an OEM wiper washer control switch designed for use in Komatsu heavy machinery, such as excavators, loaders, and dozers. This rotary knob-style switch features a durable plastic and metal construction with a prominent 'WIPER WASHER' label and icon for intuitive operation. It controls windshield wiper functions, including variable speeds and washer activation, ensuring clear visibility in harsh working environments like construction sites, mining operations, and forestry. Key benefits include reliable performance in extreme conditions, easy installation via plug-in connector, and compatibility with 24V electrical systems common in industrial vehicles. Compared to generic aftermarket switches, the TY9878 offers superior OEM quality, better resistance to dust, vibration, and moisture, reducing downtime and maintenance costs. Drawbacks may include higher cost than non-OEM alternatives and potential obsolescence for older models. Based on attached images, the unit appears used but functional, with minor wear on the housing and intact wiring harness. No parent/child assets are visible. For detailed specs, refer to Komatsu parts manuals.
