Thyrm Switchback 2.0 Large Flashlight Ring


Flat Dark Earth (FDE)
Urban Grey

Product Description

The SwitchBack® 2.0 adds a multi-function finger ring and a 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.

The SwitchBack® 2.0 is the next evolution in the innovative SwitchBack Flashlight Ring product line. It incorporates new features and refinements based on thousands of hours of use by our subject matter experts and customers. The SwitchBack 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. It allows 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 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 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 creates 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.

Tailcaps larger than 1.004 inches (2.55016 cm) in diameter are not compatible with the SwitchBack Large 2.0.

For installation, first, try installing the SwitchBack on your light without the use of the o-ring or aluminum washer. Simply unscrew the tailcap, add the SwitchBack, and re-screw the tailcap back on. If the light does not activate upon the 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 the addition of the rubber o-ring will help to stabilize the position of the SwitchBack.

Interesting idea that doesn't work for me.

It's too thick and big, and blocks my trigger finger with a proper support hand grip. Might work if it was skinnier, smaller diameter, with no thumb rest. Would like one that works with stream light macrostream or microstream.
