Built for Real Farm Work
This is the kind of switch you’ll find controlling auxiliary hydraulics, work lights, fans, or any accessory that needs reliable switching on tractors, combines, and other farm equipment. Whether you’re running older machinery that needs electrical repairs or adding custom controls to newer equipment, this switch handles the job without the fancy price tag of OEM parts.
Made to Last
Farm electrical components take a beating from vibration, temperature swings, and the occasional bump or splash. TISCO builds these switches with contacts that resist arcing and corrosion, so they keep working season after season. The housing is designed to seal out moisture and dirt while standing up to the constant switching that farm work demands.
Installation Notes
This is a straightforward replacement—just match up your three wires to the three terminals and mount it in your existing switch hole. Always disconnect the battery before working on electrical components, and a little dielectric grease on the terminals helps prevent future corrosion problems.
