The Makita 418016-5 Switch Knob is a genuine OEM replacement part designed to restore reliable on/off control to small Makita angle grinders, including the MT952, GA4030R, GA4530R, and GA5030R. Manufactured to Makita's own specifications, this knob is moulded from hard-wearing black plastic to withstand the demanding conditions of regular site and workshop use. It seats precisely on the switch mechanism, delivering a firm, accurate slide action and consistent engagement with each operation.

This direct-fit replacement resolves that problem without modification, using only basic hand tools to install. Whether you're returning a heavily used machine to service or addressing a broken control before the next job, this genuine Makita component ensures your grinder operates as intended and helps extend the tool's working life.
