This product is a tail cap switch only. This is NOT the remote switch assembly. This item is used to either replace your push-button tail cap insert or to change from a remote switch to a push-button variant. REIN utilizes an optional proprietary switching that gives you unparalleled performance. Giving you constant and momentary functionality, it is the strongest and most reliable remote switch available. And it is fully submersible to 100ft of water for 24 hours.
The REIN push button switch is compatible with both the REIN full-size and REIN Micro. Not compatible with any other flashlight brand.
