Bosch Speed Governor 110-120V - 1617233027

Genuine Bosch 1617233027 — Speed governor / speed control 110-120V

- What it is: Genuine Bosch speed governor (electrical speed-control assembly) used to restore stable RPM and responsive speed adjustment on compatible Bosch demolition/rotary hammers.

- Typical construction and rating: Compact plastic housing with internal metal contacts and mounting points; designed for 100–120 V tool control circuits.

- Fits (example models): common fits include Bosch 11216EVS, 11219EVS, 11220EVS, 11223EVS, 11230EVS, 11232EVS, 11245EVS and related 113xx/112xx EVS-series demolition hammers — and is also used in some GSH-series breakers such as GSH 10 C and GSH 5 CE. (Check your tool’s model label for an exact match.)

- Why you’d choose it: Direct-fit original Bosch part engineered to the tool’s tolerances so the speed control, trigger response and built-in safety behavior match the factory design — a straightforward swap into the tool’s control cavity using basic hand tools.

If your tool shows erratic speed, won’t maintain power under load, or the trigger speed adjustment is intermittent, this original Bosch speed governor restores reliable control without modifying the tool.
