This is the High/Low Bezel Switch for the MD2 Flashlight. Simply install this brass switch in place of the aluminum lamp retaining ring on the MD2. The light will now have high output when the head is snug and low (10-20 lumens) output when the head is rotated out from snug to about 1/2 turn. Rotate further out to achieve lockout and prevent accidental turn on. Will also work with MD3 and MD4 bodies with MDX head.
This Switch Will Not Work With Flashlights Other Than The Malkoff MD2, MD3, or MD4 with MDX Head.
This Switch May Have Unpredictable Behavior With The M361 LMH (and variants) and M31 (and variants) Drop-ins.
