HD Switch Starter Ignition Key Switch 539101770 539 10 17-70 Fits AYP Craftsman Husqvarna Jonsered Poulan AYP - Ultimate Dual Dust Protection Upgrade

STOP #1 CAUSE OF FAILURE: Most switches fail when dust and water infiltrate the unprotected keyhole causing abrasive buildup. The HD Switch Dual Protection System seals these entry points, shielding your ignition from the elements that cause failure. DUAL-LAYER PROTECTION: Combines our custom-fit Rubber Grommet/Nut System and Protective Umbrella Key to shield the ignition’s internal components. GROMMET AND NUT SYSTEM: The Rubber Grommet & Nut System provides a basic seal that keeps water and dust out when the machine is not in use, and the key is out. ENGINEERED FOR EXTREMES: Designed by HD Switch to provide maximum durability and reliable starts, providing protection in the harshest outdoor conditions. COMPLETE KIT: Includes Premium Ignition Switch, HD Switch Protective Grommet & Nut, Soft Grip Umbrella Key, Spare Metal Key, and one set of standard mounting hardware. HD Switch Dual Protection Ignition Kit: Engineered to prevent the #1 cause of ignition failure—internal component wear. Standard keyholes allow dust and moisture to enter, forming abrasive buildup that degrades performance over time. Our premium kit uses a dual-layer shield to lock out the elements, ensuring your equipment starts every time, even in the harshest outdoor conditions
