638882-6 supersedes older part numbers: 650578-9
Makita 638882-6 — Switch (TG553FSB-6) — genuine Makita trigger/switch assembly designed to restore reliable on/off and variable trigger control in affected rotary/combination hammers. This direct-fit switch features a compact black plastic housing with reinforced metal contact points and the factory TG553FSB-6 mechanism so it lines up with the original wiring and mounting locations used on the tool.
Fits (example models): Makita BHR202 and DHR202 (listed in the official parts diagrams).
Note: this part replaces an earlier switch used on some BHR162 (previous Makita part 650578-9), other models include BHR202 and DHR202
Why choose this part: it’s the original Makita switch assembly that restores smooth trigger response and resolves failures like intermittent starting, stuck triggers, or loss of speed control—installed in the same location and wired the same way as the factory unit for straightforward replacement.
