The SwitchBack® 2.0 adds a multi-function finger ring and robust pocket clip to your tactical flashlight. It mounts securely between the light’s tailcap and body, providing a repeatable grip index during deployment from pocket or pouch, and enhances ergonomics while shooting or searching. Watch the video below to learn more.

The SwitchBack® 2.0 is the next evolution in the innovative SwitchBack Flashlight Ring product line, incorporating new features and refinements based on thousands of hours of use by our subject matter experts and customers. The SwitchBack 2.0 mounts between the tailcap and body of your flashlight, making it secure regardless of impact, moisture, and heat/cold changes. SwitchBacks can be used with handguns or long guns, allowing the user to:
• Reliably deploy and index a flashlight from both pockets and pouches, using the SwitchBack’s rigid, but releasable, retention ring.
• Shoot using a natural two-handed grip (the SwitchBack Technique).
• Employ all traditional low-light techniques such as Neck Index, Modified FBI, and Harries.
• Positively retain the light when drawing a firearm, reloading, and addressing a malfunction.

The SwitchBack 2.0 also provides fast deployment and enhanced retention during many activities such as climbing, backpacking, car and home maintenance, and self-defense.

New for SwitchBack 2.0:
• A finger ring that releases under heavy force/torque, but can be reset.
• A stronger pocket clip that also works with MOLLE/PALS webbing.
• A pocket clip position that allows for slightly deeper carry than the SwitchBack® Large (original).
• A tubular portion that is cut lower to allow grip on both sides of the tail-cap during installation.
• A wider thumb rest with traction features.
• Small crush ribs on the SwitchBack 2.0’s lip that create a custom fit across a broader range of lights.
• An aluminum spacer that expands compatibility to Streamlight HL and HL-X flashlights and other manufacturers with similar designs.

Designed and manufactured in the USA.

Looking for a SwitchBack Flashlight Ring to fit a smaller-diameter light? Check out the SwitchBack S Backup.  We also offer the original SwitchBack Large’s design.

Curious about compatibility with your other 1-inch diameter lights? Contact us if you have questions about your model.

Tailcaps larger than 1.004 inches (2.55016 cm) in diameter are not compatible with the SwitchBack Large.

For installation, first try installing the SwitchBack on your light without use of the o-ring or aluminum washer.  Simply unscrew the tailcap, add the SwitchBack, and rescrew the tailcap back on.    If the light does not activate upon use of the tailcap switch with the SwitchBack installed, try installing the aluminum washer as shown in the diagram below.  Streamlight models tend to require the aluminum washer, but may not, depending on the tailcap features of the light.  Elzetta and Surefire models do not usually require the aluminum washer, but users may find that addition of the rubber o-ring will help to stabilize the position of the SwitchBack.

    Very sturdy. Goes well with my edc setup. Buy from BTO with confidence!

  2. Reborn (verified owner)

    Recommended to me by some friends since I’m relatively new to handhelds, this thing definitely helps and allows me to use a light with a firearm. It does take some getting used to, but it works great once you get the hang of it.

  3. Zach1 (verified owner)

    At first I thought these would add too much size to the light but after giving one a try I buy them for all of my hand held lights. The clip is secure and it isn’t too big at all. The finger ring allows for fast deployment, good retention, and helps if you need to use your light with a sidearm. It will still allow you to use a near normal two handed grip on the firearm and use the light at the same time.

    Great option for EDC handhelds, allows you to better retain the light during searches.

  5. Nathan Norton (verified owner)

    Perfect addition to any EDC. The modlite is a tad big for me personally to carry on my person, but it’s perfect to add to ready rigs or carry in backpacks and have ready. The ring is perfect size. I thought the ring was going to be bigger and bulker but I was very happy when I received it and it fits my hand just right. A definite modification to any flashight especially if that’s all you can carry is a light source with you.
