Makita 632E12-1 Spare Part - SWITCH UNIT DGA454/505/508
Original Makita switch unit (part no. 632E12-1) — a direct replacement switch assembly for 18 V LXT paddle/body‑grip angle grinders. This compact switch module restores reliable on/off control and trigger feel thanks to a polymer housing, copper contact points and a small PCB with factory‑style connector for straightforward replacement.
Fits many Makita 115–125 mm (115–125 mm) grinders including common models such as DGA454, DGA455, DGA458, DGA467, DGA469, DGA505, DGA508, DGA517, DGA518 and DGA519. These example fitments make it a useful spare when the trigger fails, cuts out intermittently, or the paddle no longer returns cleanly.
Why choose this part: it’s an original Makita component manufactured to factory tolerances, so you get factory‑style fit, plug‑in connectors and the same switching performance as the tool left the factory. Ideal if you need a single, reliable replacement to get your grinder back to service.
Note: this listing is for the switch unit only (part no. 632E12-1). If your tool has other visible damage around the switch area, inspect the trigger lever and wiring when you install the new module to ensure a trouble‑free repair.
