Abstract
A three-axis gravity switch having a curved chamber with an inner wall in the shape of a convex hemisphere and an outer wall in the shape of a concave hemisphere which retains a gravity responsive member such as a ball of liquid mercury, the chamber having a three-dimensional sensing pathway defined on at least one of its walls, where the gravity responsive member and pathway are conductive, either electrically or optically, such that a circuit is completed when the gravity responsive member contacts the pathway, where the switch can be rotated, inverted and translated in three dimensions such that the pathway defines an acceptable three dimensional course of rotation for the switch.
