Fire your light from a pad mounted right where your thumb sits.
A drop-in tailcap that adds a remote pressure pad to your NITECORE NEW P12, MH12 v2, MH12S or NEW P30, for momentary and constant-on control on a weapon, a bike or a helmet.
- Replaces the original tailcap, no tools or modification
- Pressure pad for momentary on, tail side switch for constant on and off
- Coil cable sits tight at about a foot and stretches to 22 inches
- Mode memory preserved, returns to your last setting
- Tail diameter 28.6mm, total length 306.6mm

Remote activation, mounted where you need it.
Swap on the RSW3 in place of the standard tailcap and run the pad to the spot your thumb naturally rests, a weapon rail, a handlebar or a helmet bracket. You keep your firing grip and trigger your light without reaching for the tail.
The tough coil cable holds at roughly a foot when compressed, so it stays tight and snag-free, and stretches to 22 inches when you need the reach across a longer platform.

Momentary and constant, two ways to drive it.
With the light off, press and hold the pad for momentary light and let go when you are done, ideal for a quick scan that leaves no trail. For a hands-off beam, click the side switch on the tailcap for constant on and off.
The constant switch preserves mode memory, so your light comes back on at the brightness you were using before. The side switch on the flashlight body still cycles your brightness levels and special modes as normal.

Unscrew the standard tailcap from your light and thread the RSW3 on in its place, no tools needed.
