Five Terminal Ignition Switch for Vintage Iron Tractors

Description

Nothing’s more frustrating than turning the key on your vintage tractor and getting nothing—especially when you’ve got work to do and that old machine has been sitting in the shed all winter. If you’ve been dealing with a wonky ignition switch that needs just the right touch or doesn’t make solid contact anymore, this replacement gets your vintage iron starting reliably again. With its .995″ diameter threaded end and included jam nut and two keys, it’s designed to be a direct replacement for worn-out original switches.

What You’re Getting

• Precision .995″ diameter threaded shaft fits standard dashboard mounting holes perfectly
• Five spade terminals with screws provide secure electrical connections that won’t vibrate loose
• Complete installation kit includes jam nut for proper mounting and two keys so you’ve got a spare
• Heavy-duty construction handles the electrical loads and vibration that come with farm work
• Positive detent positions give you that satisfying click so you know it’s engaged properly

Built for Real Farm Work

This switch is specifically designed for Vintage Iron applications, covering a wide range of older tractors and equipment that used five-terminal ignition systems. These machines were built to work hard day after day, and this replacement switch maintains that same reliability. Whether you’re running an old row-crop tractor, a utility machine, or vintage farm equipment, this switch handles the ignition, accessory, and starter circuits just like the original.

Made to Last

Vintage tractors put switches through their paces—constant vibration, temperature swings, and years of use can wear out even the toughest components. This replacement features robust internal contacts that handle starter motor loads without burning out, and the five-terminal design with screw connections ensures your wiring stays put even on the roughest ground.

Good to Know

Installation is straightforward if you label your wires before removing the old switch. The five terminals typically handle battery power, ignition, starter, accessories, and ground—but wire positions can vary by application. A little dielectric grease on the terminals prevents corrosion, and it’s worth checking all your connections while you’ve got everything apart. Keep that spare key in a safe place where you can find it when you need it.
