ABSTRACT:
A switch and alarm system capable of detecting any one or more of the conditions of angular tilt, vibration or sudden movement includes a conically shaped movable contact suspended within an aperture in a fixed contact. The cone forming the movable contact is preferably suspended with its apex down to thereby render it inherently unstable, and hence sensitive to any applied vibrations. The sensitivity of the switch to the conditions to be detected can be adjusted by varying the height of the movable contact relative to the stationary contact to thereby vary the spacing between the two contacts. In addition, the radial position of the cone relative to the aperture in the stationary contact can be adjusted to permit the switch to be used in a variety of applications.
