Original Makita 650579-7 on/off switch — a direct-fit replacement switch that restores reliable power control to compatible Makita angle grinders. This genuine Makita push‑button style switch is built to the same specifications as the factory part and is supplied singly for quick repairs.
Technical details: push‑button actuator with four electrical terminals (two internal, two external); actuator height ≈ 11.4 mm and actuator diameter ≈ 4.8 mm; overall switch body height ≈ 33.8 mm. Rated for typical grinder duty. These specifics make it an easy replacement when the original switch sticks, fails to click, or loses continuity.
Fits (examples): Makita 9557NB and closely related 9557/9558 series grinders, plus a number of 115 mm (4-1/2") angle grinder models such as 9558PB, 9557PB, 9564PC, 9565PC, 9566PC and some BGA/GA series variants.
Easy to install: the switch replaces the factory unit without modifications; it’s a straightforward swap for anyone comfortable opening the grinder housing and reconnecting the four terminals. Sold individually and ready to get your tool back to work.
