632J81-2 supersedes older part numbers: 632G34-3
Original Makita switch unit — part no. 632J81-2 — replacement trigger/switch assembly for the DTW190 cordless impact wrench series. This genuine Makita switch installs inside the tool’s handle to restore on/off and variable-speed control (it’s the same switch listed in Makita’s DTW190 parts diagram).
Compatible with DTW190 — for example DTW190Z, DTW190RTJ and DTW190RMJ. Useful when the trigger no longer responds or the tool won’t start.
Notes for fit and service: the DTW190 parts diagram references this unit alongside the line‑filter parts 688163‑8 and 688165‑4, so check those related components when fitting the switch. This is listed as the original Makita part for the DTW190 series, so it’s the correct replacement if your impact wrench uses that switch number. Makita spare parts are referenced directly in the DTW190 parts documentation.
