Makita SWITCH C3D-H-MS 8900N/HM1200 - 651145-3

Original Makita 651145-3 — trigger switch for Makita demolition/rotary hammers. The switch is the factory original Makita trigger assembly (sold individually) and is a direct-fit electrical replacement for several Makita hammer/drill models.

Key details: 4 electrical terminals; designed to handle on/off and variable-speed trigger control and electric-braking/polarity reversal functions used in Makita hammer tools; compact rectangular housing that mounts in the tool handle and accepts the factory trigger linkage.

Common compatible Makita models : HM1201, HM1211 / HM1211B, HM1300 / HM1301, HM1500 / HM1500B, HR3520, HR3850B / HR3850K / HR3851, HR5000 / HR5000K. Use of this part restores original switch function in the listed hammer/rotary-hammer models.

Notes for installation: sold as the single replacement switch (it replaces older part 651132-2 in Makita parts lists), installs inside the handle cavity and typically requires basic hand tools and 15–30 minutes to replace. Test continuity and proper trigger action after installation.

If your tool is one of the listed models and the symptom is a dead motor, intermittent power or a trigger that won’t vary speed or engage the brake, this original Makita 651145-3 switch is the exact replacement used in the factory parts breakdowns.
