FENIX AER-02 V2.0 Remote Pressure Switch

The AER-02 V2.0 remote pressure switch is the dedicated control accessory for compatible FENIX torches mounted on a Picatinny rail. It allows the user to activate the torch and switch to momentary mode without moving the hand off the grip, via a cable measuring 23 cm in total length, extendable to 34 cm with the tail adapter. Designed for shooters, hunters and operators running a weapon-mounted torch on a long gun.

The pressure pad produces no audible mechanical click and is rated for 100,000 actuations, a practical advantage in situations where silence and repeatability matter. The round switch on the body lets the user toggle between momentary and constant-on without losing control of the torch. One consideration worth noting: the PU cable is flexible and abrasion-resistant, but it does need to be physically secured to the weapon. The package includes both cable ties and velcro, leaving the choice of method to the operator depending on the weapon and setup.

The tail adapter is machined from T6 aluminium with a Type III hard anodised finish, making it abrasion-resistant and non-reflective. The IP68 rating ensures dust-tightness and waterproofing to a depth of 2 m. The mating thread is Tr22.4x1.5 mm; the adapter measures 25.4 mm in diameter and 31.5 mm in height. Total weight is 40 g.

Key points

• The silent pad eliminates mechanical click, reducing acoustic signature during actuation.
• The rated service life of 100,000 actuations ensures long-term reliability without frequent replacement.
• The IP68 rating to 2 m allows use in heavy rain or shallow water crossings without additional protection.
• The 23 cm PU cable provides flexible positioning across rifles of varying lengths, secured with the included cable ties or velcro.
• The T6 aluminium adapter with Type III hard anodising resists abrasion without adding reflectivity.
