This electrical switch controls a function within the combine's electrical system. It is a direct-acting component that opens or closes a circuit based on operator input or a mechanical condition in the assembly. When the switch fails, the controlled function either stops responding or operates intermittently, which can halt the work process until the circuit is restored. As an original part, the housing geometry and contact rating match the factory specification, ensuring the switch seats correctly in the panel and carries the intended load without overheating.
