Abstract
A drop detection device having a spherical inertia member disposed within an enclosure. The enclosure has multiple faces, preferably six faces oriented orthogonally, with each face having a pressure contact member. The exertion of a predetermined force by the spherical inertia member on the pressure contact member causes a signal to be activated. Multiple enclosures maybe disposed in different orientations in a housing of a fragile product to provide a signal if the product is dropped in any one of multiple directions.
