Original Metabo switch, part number 343411870 — HY-28, 230 V on/off switch with built‑in restart protection and an EMC suppression capacitor, made for 115 / 125 mm Metabo angle grinders.
Common fits : Metabo W 11‑125 Quick (03623000), W 9‑125 series (00374000 / 00376000) and the W 9‑115 / W 9‑115 Quick . These listings indicate the part is the direct replacement switch used in those 125 mm grinders.
What you get: a single original Metabo HY‑28 switch (matched mounting and electrical specification for the listed machines) that restores safe on/off control and the tool’s EMC / restart protection functionality. If you’re replacing a faulty or intermittent switch, this is the correct Metabo parts item to match the factory electrical characteristics — just confirm your machine number and voltage on the nameplate before fitting.
