Surefire
The Surefire CSM-09 Weaponlight remote switch gives you control over your mounted light without occupying valuable rail real estate. If you run a modern carbine, pistol, or shotgun with a SureFire WeaponLight, this M-LOK mounted switch lets you activate your light from the side or rear grip—a cleaner setup that keeps your handguard uncluttered and your support hand in a natural position. The switch manages both momentary-on (light press) and constant-on (full click) from a single intuitive control, giving you flexibility whether you're navigating a room, scanning a berm, or searching rough country at night.
Built from durable polymer, the CSM-09 clamps solidly to M-LOK rails and is sealed against weather and debris. SureFire engineered it to the same uncompromising standard as their lights themselves—no rattles, no creep, just rock-solid activation when you need it. The weatherproof switch and plug mean you won't worry about it in wet conditions or dusty use.
Compatibility is broad: the CSM-09 works with SureFire WeaponLights that feature plug sockets, covering Millennium Universal, Classic Universal, Scout Light models fitted with socketed tailcaps, X300, and X400 with XT tailcap assembly. Before ordering, verify your light has the socketed tailcap interface; this remote switch isn't designed for lights without the proprietary connector.
| Brand | SureFire |
| Model | CSM-09 |
| Mount Type | M-LOK |
| Color | Black |
| Housing Material | Polymer |
| Switch Type | Momentary-on / Constant-on |
| Weatherproof | Yes |
The CSM-09 remote switch is compatible with SureFire WeaponLights featuring plug sockets, including Millennium Universal, Classic Universal, Scout Light (socketed tailcap models), X300, and X400 with XT tailcap assembly. Your light must have the socketed tailcap interface; non-socketed lights won't support this switch.
The CSM-09 is designed with an M-LOK clamp for M-LOK rails. The supplier description mentions Picatinny compatibility, but the standard CSM-09 model uses M-LOK attachment; confirm your rail system before purchasing.
A light press of the switch gives momentary-on—the light stays on only while you're pressing. Click it fully and it locks into constant-on, staying lit hands-free until you click it off again. One switch handles both modes.
Yes. Both the switch and plug are sealed against weather and moisture, so it's reliable in rain, snow, and dusty conditions.
