Original Makita compression spring — part 231469-9 — listed as "Compression Spring 4" (4 mm diameter) and used as the small compression spring behind the switch / lock‑off lever on many Makita saws and saw‑type tools.
This genuine Makita replacement restores proper button and switch action on models such as BSS610 / BSS611, JR140 / JR180 , CC301D , BCS550 and DUC307 shown in Makita parts diagrams, so it’s an exact match where that spring has gone missing or lost tension.
A simple, low‑profile compression spring made to original Makita spec — ideal when you need a single part to get your tool switching crisply again. Keep this item with other small power tool parts for quick repairs; the spring seats under the lock‑off or switch lever as shown in the parts breakouts.
