A non-threatening combination baton and spray dispenser that can be readily employed was a baton or as a dispenser without requiring complex re-orientation or concentrated aiming, including an expandable baton having a mounted connector coupling that facilitates connection to an end of an irritant spray dispenser disposed in axial alignment with the baton. The connector coupling supports a switch mechanism readily operable by the user's thumb while grasping the connector coupling to selectively dispense spray axially from the dispenser with the baton in either its retracted or expanded positions. The dispenser preferably utilizes the barrel and lens support end of a flashlight to facilitate use as a flashlight or for conversion to receive a pressurized chemical irritant cartridge, and enables selective interchangeability of nozzle plates of different color exposed surfaces to simulate a flashlight lens, provide a dark, non-reflective color during night maneuvers, or use a bright color so that a subject is readily aware that an irritant spray dispenser is pointed at him. The switch mechanism includes a safety button selectively operable to prevent unintended actuation of the dispenser.
