Description

When your starter button stops clicking or your horn won’t honk, it usually comes down to a worn-out push button switch. These little switches get pressed hundreds of times during a season, and eventually the contacts wear out or moisture gets in and causes problems. This replacement switch assembly gets your MF35 or MF65 back to reliable starting and proper horn operation.

What You’re Getting

Heavy-duty momentary contact design that handles the electrical load without burning out
Weather-resistant housing that keeps moisture and dirt from getting to the contacts
Standard 5/8-inch mounting diameter fits your original dash or firewall opening perfectly
Dual-purpose design works for both starter activation and horn operation
Quality construction built to handle thousands of presses over many seasons

Built for Classic Massey Ferguson Work

This switch is designed specifically for the MF35 and MF65 series tractors—machines that have been workhorses on farms for decades. Whether you’re using your MF35 for hay work, cultivating, or general farm chores, or running your MF65 for heavier field operations, having reliable starter and horn switches is essential for safe, efficient operation.

Made to Last

Farm equipment switches take a beating from vibration, temperature swings, and daily use. This assembly is built with robust internal contacts that won’t stick or corrode, and the housing is designed to seal out moisture while standing up to the constant vibration of tractor operation. The spring-loaded mechanism provides consistent tactile feedback so you know when you’ve made contact.

Good to Know

Installation is straightforward—the switch mounts in a standard 5/8-inch hole in your dash or firewall. Make sure to disconnect the battery before wiring, and use dielectric grease on the connections to prevent corrosion. If you’re replacing both starter and horn switches, it’s worth doing them at the same time since they’re likely the same age and wear pattern.
