Original Makita switch knob — part number 418016-5 — slide-style switch actuator (JS1602/JS1600 family) used on small Makita grinders and cutters.

Moulded from hard-wearing black plastic with a textured grip, this knob restores a positive, low-profile slide action so the on/off switch engages cleanly even under dust and vibration.

Listed among common Makita parts, it’s a direct-fit replacement for a number of compact angle grinders and related models — examples include GA4030R, GA4530R, GA5030R, MT952 and JS1602/JS1601 (other small Makita slide-switch tools may also use the same actuator).

Simple to install — the cap seats onto the existing slide-switch mechanism and is intended as a drop-in swap with no modification required, so you can quickly get a tool back into service.
