Fenix AER-05 is a remote gel switch dedicated to the Fenix TK16 V2.0 flashlight. The switch provides precise operation and quick mounting on the weapon with velcro tape or zip ties.

The AER-05 is equipped with two buttons, i.e. a noiseless pressure switch (without a click) with high sensitivity for activating momentary light and changing modes, and a round tactical switch (with a click) for initiating flashlight operation and continuous illumination.

The life of the buttons is 100,000 uses and they are capable of transmitting 3 A of current before a long time. Thanks to the suggestions of users, the second generation of switches uses a straight cable with an optimal length of 23 cm made of flexible PU plastic.

The flashlight tightening adapter (TR22.4×1.5 mm thread) was made of T6 aluminum. The metal has undergone HA-III hard anodizing, which guarantees very high resistance to abrasion and scratching. The design of the AER-05 is IP68-rated, making the switch resistant to dust, fine solids, and total immersion in water 2 meters deep for 30 minutes. The AER-05 is designed for flashlights powered by a 2100 cell, with an APF control system. The switch can be attached to the weapon in two ways, viz.

• With Velcro (included) - which allows quick attachment and detachment of the switch
• With the help of 4 zip ties- for long and regular use.
