After releasing the XT series, Klarus realized that their lights were a great choice for a weapon mounted light, yet it did not have a specifically designed pressure switch for the lights. Introducing the Klarus TR11 and TR12 pressure switches, which are the first of its kind that allow the user to cycle through the modes via the switch. The TR11 and TR12 have a dual button switch: a larger primary switch used for momentary light, and a secondary to access a constant beam and cycling through the modes (including strobe). The TR11 switch will fit the XT1A, XT1C, and the XT2A, while the TR12 will fit the XT2C.
