Fenix AER-03-V2 Straight Cable Remote Pressure Switch

For Use with the Fenix TK16, TK20R, TK32, TK25IR, TK25UV, TK25RED, TK25R&B Flashlights

The Fenix AER-03-V2 is the new edition of the Fenix AER-03 Coiled Cord Remote Pressure Switch. This new version has a straight cord instead of coiled for less tangled or dangling wires. Specifically designed to be used as a tactical and hunting accessory for the Fenix TK16 and TK32 (2015 Edition) flashlights. The dual switches provide you with different lighting activation options that suits your situation the best. The switches are virtually noiseless, so you don't have to worry about your position being given away as you activate it. Easily mount the switch pad to most gun barrels with two different customizable and secure attachment points. Choose between the velcro hook and loops or the cable ties (included) for convenient fixation. The cable itself is made from durable polyurethane material and measures a little over 9 inches. Its tail adapter is constructed from T6-grade aluminum with a Type III hard-anodized and anti-abrasive finish to guarantee strength and resilience through tactical use and punishment. The anti-glare, all-black finish is to assist in your concealment during situations where you need to stay hidden. The IP68 waterproof rating allows you to use this switch in any weather without fear of damaging it. To make it a complete package, pair this switch with the Fenix ALG-01 Flashlight Ring for an ultimate hunting and tactical lighting experience.
