Makita 632D81-6 — Switch Unit — genuine Makita replacement module designed to restore the trigger/switch function on compatible Makita left‑hand circular saws. This molded switch assembly replaces the internal trigger and contact block and installs into the handle as a direct‑fit replacement for DHS680 style 165 mm circular saws.

If your saw shows no response when the trigger is pulled, intermittent power, or a failed safety interlock, replacing the 632D81-6 switch unit is the correct repair part listed for the DHS680.

This is a genuine Makita switch unit supplied as the complete trigger module (pre‑assembled contacts and harness interface), so you replace the entire electrical switching assembly rather than individual contact plates — a straightforward swap that gets the tool back to reliable operation. Makita spare parts inventories commonly list this unit under the SWITCH UNIT designation. Power tool parts like this switch are the simple replacement you need to restore normal function quickly.
