SwitchBack S SureFire EDC Flashlight Ring

SwitchBack Backup S Flashlight Ring in Urban Grey with Costa Ludus Logo

The SwitchBack S Backup Flashlight Ring enhances your compact flashlight, optimizing ergonomics for searching and shooting.

Designed in collaboration with Chris Costa, Costa Ludus. Designed and manufactured in the USA.

The SwitchBack S Backup comes with two o-rings.  See below for compatible lights and recommended o-ring to use.  Shrouded and flared tailcaps are not compatible (a flared tailcap is shown in the image at left/above).

Note that the E1B- Backup MaxVision comes with a shorter tail cap so that this flashlight cannot be activated with the knuckle in the SwitchBack Technique.  Instead, users turn the light on with a finger, then can modify the position of the light using the SwitchBack.

The SwitchBack S Backup is not compatible with lights larger than 0.830 inches (2.1082 cm) in diameter.  Have a 1-inch diameter light? Check out the SwitchBack Large 2.0. Looking for a 1.12 inch inner diameter Flashlight Ring? Try the SwitchBack DF.
