Makita 631695-4 — Power Supply Circuit (genuine Makita). Direct-fit replacement power‑supply / PCB assembly for the Makita BSS610 / DSS610 18V LXT Cordless 165mm Circular Saw
This is the complete internal power‑supply board (item #006 in the diagram) that installs behind the handle and plugs into the tool’s lead / terminal harness — supplied as the assembled circuit board so you replace the entire module rather than individual components.
When the saw exhibits electrical faults such as failing to start, intermittent power, or battery recognition problems (with motor and battery otherwise OK), replacing the power supply circuit is a common repair to restore correct power regulation and control.
This is a genuine Makita replacement listed for BSS / DSS 610 Circular Saw — make sure the tool model matches your saw and the part number 631695-4 when sourcing the correct component.
