The Surefire SR07 is a great accessory for Surefire scout lights and the X300 light. Aside from a standard pressure switch which activates the light with firm pressure, the SR series of switches come with a shielded click on, click off switch which afford users more versatility: if the support hand has to leave the weapon to manipulate the enviroment (opening doors, turning switches, etc) the light on the weapon can remain on.
A very useful upgrade for your Surefire weapon light.
The SR07 provides remote activation for any SureFire WeaponLight with a switch socket. Two switches—a momentary-on pressure pad switch and a constant-on pushbutton switch—are integrated with a snap-on clamp for easy attachment to your firearm's Picatinny rail forend. The seven-inch cable length works with most rifle/carbine applications.
