Abstract
A trigger mechanism with soft stops and associated method for activating a switch in a device or apparatus. The trigger mechanism includes a trigger receptacle, a trigger disposed in the trigger receptacle and movable between an un-actuated and an actuated position by a user depressing the trigger, and a soft stop comprised of at least one projection positioned to engage a resilient elastomeric insert. Moving the trigger from the un-actuated to actuated position compresses the elastomeric insert with the projection and activates the switch to provide a tactile sensation of the switch activation to the user. The switch may be an electric switch disposed in a hand held device, such as a barcode scanner in some embodiments.
