Abstract: A tap-resistant security circuit. In the preferred embodiment, the apparatus includes a conduit including an electrically conductive wire surrounded by a gas-filled, gas impermeable sheath. At one end of the conduit is a pressure switch which is normally open but is maintained closed by the pressure in the gas-filled conduit. The other end of the conduit is sealed.

As a result, any attempt to by-pass or "tap" the wire results in the current through the wire being interrupted.

Abstract: A rotary switch convertible from being operable over a smaller range of angular motion, e.g. as a two-position switch, into being operable, in either of two configurations, over larger ranges of angular motion, e.g. as a three-position switch. A rotor and a stator are assembled for relative rotation. Four lugs divide a face of the stator into four quadrants. Two pairs of lugs, each comprising a removable lug and a permanent lug, are provided on a face of the rotor. The faces are juxtaposed such that relative rotation of the rotor and the stator is limited by interference between certain of the lugs on the rotor and certain of the lugs on the stator. Before removal of either removable lug, the rotor and the stator may be assembled for a smaller range of angular motion. After removal of both removable lugs, the rotor and the stator may be assembled in either of two configurations for larger ranges of angular motion.

Abstract: A normally-open pressure actuatable switchmat comprising first and second electrically conductive members separated by non-conductive material having a failsafe safety switch is provided. When the switchmat is subjected to an actuation load, there is relative movement between the first and second electrically conductive members to complete an electrically conductive path therebetween. The safety switch comprises a bridging member which includes an electrically conductive spring which is held in a compressed state by frangible restraining element such that, when the switchmat is subjected to a predetermined minimum overload, the frangible restraining element is broken allowing the spring to relax thereby completing an electrically conductive path between the conductive members. This path is maintained after removal of the overload thereby allowing the switchmat to failsafe.

A cover engages the periphery of the gasket and includes interengaging means cooperating with the base member to lock the covering gasket to the base member to form a hermetic seal over the cavity.

Abstract: Motor vehicle windows are commonly made of a tempered glass which shatters over its entire area whenever any part of the window is broken. Further, such windows are generally supported at the bottom edge by a channel which extends only part way along the glass leaving an unsupported part of the glass. A switch in the vehicle door is arranged to be held open by the glass and to exert a force against the glass so that if it becomes shattered, the switch force pushes the glass out of the way allowing switch closure. The entire switch is secured to the unsupported edge of the glass or alternatively the switch is mounted on the door panel and only an actuator is secured to the glass.
