Metabo Switch - 343408530

343409430 supersedes older part numbers: 343408530

Original Metabo power switch (part number 343409430) — a direct replacement switch for corded Metabo angle grinders. This original Metabo unit carries the power from the mains cord to the motor and is supplied as a single, ready-to-install switch that fits the factory switch cavity and wiring harness.

Compatible with a range of Metabo corded angle grinders (examples include W8‑115 — 115 mm disc, W8‑125 — 125 mm disc, WP8‑115 QUICKPROTECT, WB11‑125 QUICK and W11‑150 — 150 mm disc), so it’s a good match for many 115–150 mm models.

Typical symptom of a worn switch is difficulty starting the grinder (it may start intermittently or run only after a few attempts); replacing the switch restores normal on/off operation. The part is intended as a direct replacement — drop‑in fit for the listed models.
