Hitachi 955-509 Spare Part - Switch (1p Screw Type)

Original Hitachi switch (part no. 955509) — single‑pole on/off replacement designed for Hitachi/Hikoki angle grinders. Catalogued as a 1P (single‑pole) switch in Hitachi parts diagrams and sold as the solder‑terminal style in several parts lists.

Details: compact single‑pole switching unit intended to drop into the grinder’s original switch cavity; listed descriptions show both a solder‑terminal version and equivalent screw‑terminal listings under the same part number, so match the terminal style on your tool before fitting. Keep one with your power tool parts for a fast, reliable repair that restores normal on/off control.

Fits (example models): G10SS and several other G10/G12 series angle grinders (examples include G10SS, G10SN2, G10SS2 and G12SS). Use the switch as a direct replacement where the part number and switch shape/terminals match.
