Abstract: A lamp assembly for use in an automotive applications which contains a switching assembly and a light bulb. The assembly may be mounted on the underside of an automobile hood or trunk and illuminates on angular movement of the hood or trunk. The switching assembly operates through the movement of a sphere within a tube which rests on a pivot block. The movement of the sphere within the tube causes a contact to engage and disengage from two terminals of a bridge switch. When the trunk or hood is closed the contact is disengaged and the light bulb is off. However, when the assembly is rotated 26.degree. from its position when the trunk or hood is closed, the contact bridges the terminals of the bridge switch and the light bulb illuminates. The contact disengages as the trunk or hood closes past 26.degree. and before 10.degree. from its closed position, and the bulb turns off.

Abstract: A vacuum valve/switch assembly is presented. The switch is a combination of an electrical switch assembly and a vacuum dump valve, which operates in a predetermined sequence. The switch consists of a brass ferrule and two cantilever spring contact legs, identical to the existing cruise control brake switches. The vacuum valve consists of an "O" ring in a groove on a floating valve stem. The floating action of the stem permits the "O" ring to center itself in the valve seat. The "O" ring seals by virtue of a compressing spring and the pressure gradient created by the vacuum.
