Makita 418728-0 — Switch Lever B (original Makita). A molded switch actuator designed to replace a worn or broken lever on Makita small angle grinders and compatible straight grinders; it transfers finger movement to the tool’s internal on/off switch and installs into the switch housing.
Fits (examples): Makita 9556NB, 9557NB and 9558NB angle grinders and GD0601 / GD0602 straight grinders.
Details you’ll want to know: molded, impact‑resistant polymer construction for reliable actuation and long service life; supplied as a single Switch Lever B (part no. 418728-0). Approximate dimensions are about 55 mm long × 15 mm wide × 10 mm thick (may vary slightly by model).
Simple direct replacement — if your grinder’s slide / trigger lever is cracked, loose, or not engaging the switch properly, this original Makita lever restores positive, safe on/off control.
