What It Is

This is a 4-position, 7-terminal ignition switch with keys, designed for riding lawn mowers and tractors. It controls starting, running, and stopping the engine, and is a direct replacement for OEM part numbers 175566, 175442, 163968, 532175566, 925-1741, GY20074, and 94762.

Fitment & Compatibility

Before buying, confirm your mower’s brand and model. This switch fits many Husqvarna, Craftsman, John Deere, MTD, and Murray riding mowers, but not all. Check your current switch’s terminal layout: it must have 7 terminals in a specific pattern (typically 2 rows of 3 plus 1 offset). Measure the mounting hole diameter – it should be about 1.25 inches (32mm). Verify the key shape and number of positions (Off/Run/Start/Accessory). If your mower uses a different terminal count or key pattern, this won’t work.

Key Things to Know

• Quality: At this price, it’s a reliable aftermarket part. Some users report the key is slightly thinner than OEM, but it functions fine.
• Installation: Easy – just disconnect the battery, remove the old switch (often a nut and washer), and plug in the new one. No wiring modification needed if terminals match.
• Gotcha: The 7-terminal design is specific; a 5- or 6-terminal switch won’t work. Also, some mowers have a die-cast or plastic housing that may require a different mounting depth – check the stem length (typically 1.5 inches).
• Common issue: If the switch feels loose or the key doesn’t turn smoothly, the internal contacts may be misaligned – return it immediately.

Should You Buy It

If you need a budget-friendly, drop-in replacement for a 7-terminal ignition switch on a common riding mower (Husqvarna, Craftsman, John Deere, MTD, Murray), this is a solid choice. It’s not for older mowers with odd terminal patterns or different key shapes. For the price, it’s worth trying if you confirm fitment first.
