Original Makita 231457-6 — Compression Spring (size 3). This genuine Makita compression spring is the small coil used in the switch / lock-off lever area (listed as “Compression Spring 3”) and is supplied as the direct replacement spring for those assemblies.
Compact and purpose-built for Makita switch mechanisms — the part is identified in Makita parts diagrams as item 231457-6 (Compression Spring 3) and is commonly fitted where a short, firm compression spring is required to return or hold the switch/lever. It’s a straightforward swap-in replacement among Makita power tool parts when restoring switch feel and function.
Fits (examples) — found in Makita parts breakdowns for several LS-series mitre saws and selected hammer/drill and vacuum models, for example: LS1011 / LS1011N, LS1013 / LS1013F/FL/L, LS1030N, LS1040 / LS1040F, LS1214 and LS1214F/L/FL, and HM1303 / HM1304 / HR2400 / UM140D. Use the Makita parts diagram for your exact model to confirm the same part number.
Why this part matters: when the switch feels sticky, doesn’t return, or the lock-off won’t engage, replacing this short compression spring restores the intended lever action and safety return without needing larger assemblies. It installs in the switch/lever subassembly exactly where the diagram shows, so you can replace it quickly during a repair.
Note: the part is listed in Makita parts diagrams under the number 231457-6 (Compression Spring 3); check your tool’s parts breakdown to confirm placement and quantity before installation.
