Abstract
A tilt switch having at least one conductive weight held within an inert atmosphere within a housing. The weight being free moving within the housing, moving from one end of the housing to the other as the angle of inclination of the housing is changed. At one end of the housing are positioned the contact points of at least two terminals. As the weight abuts against the terminals, electricity is conducted through the weight from one terminal to the other; thus completing a circuit. The terminals may be shaped, or the number of conductive weights increased, to increase the area of contact between the weights and the terminals. The increased surface area results in a more reliable tilt switch that has increased performance characteristics and a higher power capacity.
