Makita 651976-0 — genuine Makita trigger/power switch (TG72BD / TG73BD style). This compact replacement switch provides the on/off control inside the tool’s handle and is supplied as the complete switch assembly so you can restore reliable electrical control and safety to your tool.
Key specs: single-pole single-throw (SPST), normally-open switching, rated 15 A at 18 V DC. Terminals are screw/clamp style for straightforward reconnection. The actuator (plunger) measures approximately 5.8 mm × 6.6 mm with a travel/height of about 7.0 mm, so it matches the small push-style trigger mechanisms used in Makita handhelds.
Fits (example models): commonly used as the replacement switch for Makita cordless circular saws and compact saw/drill lines — examples include BSS611 / BSS611Z, XSS02Z, DSS611 and several small corded compact drill/saws such as 4331D, 4333D and 4334D.
Why this part: if your tool won’t start, has intermittent power, or the trigger feels loose or unresponsive, replacing the worn switch with this original Makita 651976-0 switch restores proper electrical contact and the correct fitment into the trigger housing, letting the tool behave like new again.
Installation note (brief): disconnect battery or mains power, remove the handle shell to access the switch, swap the connector screws or clamps, and reassemble. No special tools beyond common screwdrivers are normally required.
