Original Makita laser switch, part number JM23100129 — direct replacement switch for the laser guide on Makita slide‑compound mitre saws. It restores the laser on/off control for the saw’s alignment marker and is the same laser switch shown in the LS1018L exploded parts list (listed as "LASER SWITCH JM23100129").
This small replacement switch is installed behind the laser switch cover and battery area shown in the LS1018L parts diagram (see nearby parts JM23100126–JM23100128 in the diagram), and is intended specifically for Makita saws equipped with a factory laser marker. Practical example models that use this laser assembly include the Makita LS1018L (and the closely related LS1018 / LS1018LN slide compound mitre saw variants with laser guide).
Why this part matters: a failed or intermittent laser switch will leave the laser marker inoperative or uncontrollable — replacing JM23100129 returns the laser on/off function and alignment convenience without modifying the saw. Makita parts listings identify JM23100129 as the genuine Makita laser switch for the LS1018L series.
Quick specs / notes:
- Part: JM23100129 — Laser switch (original Makita).
- Fits: Makita LS1018L (10" / 255–260 mm slide compound mitre saw family).
If you need a direct, like‑for‑like replacement to get the laser marker working again, this is the original Makita laser switch used in the LS1018L saw assemblies.
