ABSTRACT:
A device is disclosed for providing a non-resettable visual indication of a shock above a predetermined value which is sustained by an object carrying the device, comprising a dome-like housing, at least part of which is transparent; a flange means secured to and extending radially outward from the dome-like housing; a plate-like biasing means secured to the dome-like housing, the plate-like biasing means and the interior surface of the top portion of the dome-like housing being spaced apart and defining a chamber therein; and an indicating body within the chamber positioned between the biasing means and the interior surface of the top portion of the housing. Prior to being subjected to a force above the predetermined value, the indicating body is maintained in a first position and when subjected to a force above the predetermined value is irreversibly released to a second position.
