Abstract
A system for spraying, according to various aspects of the present invention, includes a shuttle and a trigger switch. The shuttle and the trigger switch cooperate with discontinuous mechanical coupling. The trigger switch provides a discontinuity in bias against operation of the trigger switch by the user. Consequently, the user experiences tactile feedback before spray is released. Prior to tactile feedback, the system establishes a communication link. When spray is released, the system transmits a notice via the communication link. Such a system when equipped with pepper spray aerosol is advantageous for self-defense.
