Switch Nitecore RSW3 — remote/auxiliary switch for compatible Nitecore lights (MPN NT-RSW3)

The Nitecore RSW3 is a compact remote/auxiliary switch designed to work with compatible Nitecore flashlights. It enables remote activation and supports either momentary or latching operation depending on the host light's interface. The switch connects through the manufacturer's accessory port, providing additional control options without requiring modification of the torch body. Its low-profile design and flexible cable routing make it suitable for tactical setups, hands-free arrangements, and custom installations.

Advantages

The RSW3 adds remote functionality to compatible Nitecore lights while preserving the original housing and sealing. It offers reliable electrical contact and a tactile switch feel, allowing quick momentary bursts or sustained on/off control where supported. The compact housing and durable cable are built for field use, and the plug-in connection ensures straightforward attachment and detachment when changing configurations or accessories.

Suitable for

• Tactical weapon-mounted lighting where remote activation is required
• Helmet- or chest-mounted hands-free setups
• Remote switching for flashlights in search and rescue or inspection work
• Custom installations where inline switching is preferred over modifying the light body
