Abstract

A tilt-responsive circuit controller includes a casing defining a vacuum-sealed interior region, the casing having a first end, a second end, and a tubular portion disposed there between. A first set of conductive contacts are coupled to the first end and partially disposed within the interior region. A plurality of conductive particles is contained within the interior region, the particles each being substantially spherical and having a diameter substantially less than casing diameter. The particle diameter can also be less than the distance between the conductive contacts. The casing includes a friction-reducing substance coated on the inner surface. A second set of contacts can be coupled to the second end and a third set of contacts can be coupled to the tubular portion. The contacts can be connected solely to the tubular member, or one can be connected to the tubular member and one to an end.
