Good To Know
Q: How does this master power switch work? A: It mechanically breaks the main electrical circuit when toggled, cutting all power from the battery to the combine's electrical components. This provides a simple and effective way to ensure the system is fully off.
Q: Is this switch a direct replacement? A: It is designed as a functional replacement for the OEM 7H7290 part, and it should bolt in place and connect to the existing wiring. Always verify your machine's serial number for compatibility.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
