Surefire Csp09 Csp-09 Weaponlight Switch Black Picatinny Mount

The Surefire CSP-09 is a remote weaponlight switch designed to add control and flexibility to your tactical rifle or carbine setup. Instead of fumbling with a pressure pad mounted directly on your foregrip or rail space, this Picatinny-mounted switch lets you remotely activate your SureFire weaponlight from a secondary location—freeing up valuable rail real estate and giving you cleaner weapon ergonomics. It's built for shooters who want responsive, reliable light activation without compromise.

The CSP-09 operates through a single switch mechanism that delivers both momentary-on and constant-on activation modes: a light press gives you momentary illumination for target acquisition, while a click-through engages constant-on for sustained illumination during longer tactical movements or room clearing. The weatherproof polymer housing is engineered to SureFire's exacting standards, ensuring dependable performance in field conditions—rain, dust, or rough handling won't compromise the switch when you need it most.

Compatibility is straightforward: the CSP-09 works with SureFire weaponlights that feature plug sockets, including the Millennium Universal, Classic Universal, Scout Light (when fitted with a socketed tailcap), X300, and X400 with XT tailcap assembly. The Picatinny clamp attachment makes installation simple on standard tactical rails, and the compact profile means you won't waste rail space in the process.
