An electro-mechanical motion sensor for detecting the unauthorized movement of an object and which responds to motion in all axes is disclosed. The sensor comprises a housing having a base, cap and peripheral wall defining the interior of the housing wherein the base and cap have internal and external surfaces with a mid-point thereon and a series of radially extending electrical contacts on the internal surfaces of the base and cap. The contacts extend from about the mid point of the base and cap. A metallic post is located between the mid points on the base and cap respectively and a metallic ball is provided within the housing and is of sufficient size that it can roll freely within the interior of the housing always in contact with the radially extending contacts peripheral wall or metallic post. The metallic ball will tend to come to rest in a position against the metallic post or peripheral wall while touching one or more of the radially extending contacts such that en electrical circuit is formed by contact between the metallic ball and the metallic post or peripheral wall and the radially extending contacts which are all gold plated.
