1 x 7-pin ignition switch, 4-position key, magneto, 15.9 mm mounting diameter, compatible with MTD, HUSQVARNA, and MURRAY lawnmowers and motorized machines

This 4-position, 7-terminal key switch is an essential electrical component for managing starting, fuel, and safety functions on motorized machines such as ride-on mowers, professional brush cutters, and tillers. It integrates with common magneto systems on single-cylinder and twin-cylinder engines, without requiring an external voltage source for the ignition phase. Its 15.9 mm mounting diameter ensures immediate mechanical compatibility with standard brackets from brands such as MTD, Husqvarna, Murray, AYP, Briggs & Stratton, Poulan, and Jonsered. The robust contact design, tested for over 50,000 switching cycles, meets the durability requirements of heavy-duty use. Installation follows a simple procedure: verify the tightening torque (0.8 to 1.2 N·m), observe the polarity indicated on the housing, and connect according to the supplied diagram. This product contains no batteries or active electronic components, which enhances its reliability in environments with high humidity or variable temperature.
