ABSTRACT:
An inclination sensitive switch is provided which incorporates a support member that has a device attached to it which can serve as a fulcrum point. A lever is supported by the support member at the fulcrum point in such a way that the lever can operate as a pivotal beam which is rotatable about the fulcrum point. A weight is disposed on the lever and supported by the lever. The weight is moveable along the linear distance of the lever. At least one pair of contacts is provided wherein one conductor of the contacts is attached to the lever and another conductor of the pair of contacts is attached to the support member. Movement of the lever with respect to the support member causes disengagement and engagement of the two conductors. As the support member changes its angular relationship to a reference plane, the angle between the lever and the reference plane is also changed if the angular relationship between the support member and the reference plane reaches a sufficient magnitude. Movement of the lever with respect to a horizontal plane causes a weight to move along the length of the lever and rotate the lever about the fulcrum point under the influence of gravity. This movement about the fulcrum point by the lever moves two conductors into contact with each other and completes a circuit. Movement in the opposite direction about the fulcrum point by the lever causes the conductors to move out of contact with each other.
