Annolai 5-Terminal Ignition Switch with Key for MTD, Craftsman, Ariens, Bad Boy

Overview

Annolai presents a practical 5-terminal ignition switch with a keyed ignition, designed as a versatile replacement for many ride-on mowers and zero-turn units. The compact 5-terminal layout pairs with a 3-position switch, delivering a familiar Start, Run, and Off sequence while simplifying wiring across diverse setups. The rugged housing is built for outdoor use, and the umbrella-style key helps shield the contact area from dust and moisture. This model focuses on reliable ignition behavior without adding features like headlight control in compatible configurations.

In everyday use, the switch supports quick and confident starts, smooth re-engagement after brief shutdowns, and steady operation in dusty, damp, or sandy environments. The umbrella key protects against airborne particles and water, reducing the risk of corrosion or erratic starts in challenging conditions. The design emphasizes straightforward replacement so you can minimize downtime and get back to mowing with less hassle.
