651433-8 supersedes older part numbers: 651403-7
Original Makita replacement switch ST115A‑32 — part no. 651433‑8. Clean, black slide/rocker on‑off switch designed as a direct replacement of the switch assembly in compatible corded Makita tools; it restores normal on/off control and fits the tool housing and terminal layout used on several older Makita models. This is an original Makita component intended for quick repair jobs and small maintenance tasks involving parts for power tools.
Compatibility: commonly used in Makita routers (for example model 3606) and several 125 mm corded angle grinders and related corded tools — reported fits include models 9523NB, 9524NB, 9525NB, 9527NB and 9528NB, and some 3600‑series routers/grinders where the ST115A switch is listed. If your tool’s parts diagram shows part number 651433‑8 or “SWITCH ST115A‑32,” this is the matching replacement.
Details: the switch is a compact, black plastic ST115A style on/off unit (listed as ST115A‑32 under Makita part 651433‑8) sized about 23 × 19 × 19 mm, designed to mount into the molded housing and accept the same spade/terminal connections used in the original assembly — so it drops into the original location and connects like‑for‑like in the wiring harness. Fitment and the exact mounting index are shown on the tool parts diagrams for the models above.
If your switch is cracked, sticking, or no longer actuates the motor, this original Makita 651433‑8 switch gives you the exact replacement geometry and electrical form factor used on the factory assemblies so you can restore reliable on/off operation.
