A voltage surge suppression circuit for a low voltage coaxial cable comprises a gas tube connected across the signal and shield conductors and an MOV connecting the shield conductor to a ground. In the case of a balance signal line comprising two conductors, a first gas tube connects one line to ground and a second gas tube is connected across both conductors. A third gas tube may connect the other conductor to ground in which case the second gas tube may be optional. The ground is preferably a ground associated with a power line voltage surge suppression means.

Surge suppression for low voltage signal circuits

A voltage surge suppression circuit employs two series connected metal oxide varistors and a power interrupter to provide suppression of all modes of voltage surge while providing protection against failure of either metal oxide varistor. An indicator is provided to indicate the status of the circuit to the user.

A packaged article having a screw extending through the article is provided. The article packaged may be any article having a screw opening through it and having a screw for mounting the article into its normal place of use. In the package article of this invention the screw extends through the article and into a package to hold the article to the package. The package has a hole for receiving the screw and in this invention has also a threaded nut of polymer or pitch material bonded to the package. A method of forming a packaged article is also taught.

A light dimmer product is provided having simpler construction and simpler assembly than prior art dimmers. Simplicity of construction is achieved by providing a printed circuit board and mounting all electrical leads from components to the board to permit a single soldering operation to solder all leads simultaneously. Simplicity of assembly is achieved by mounting portions other than current carrying portions to the mounting bracket of the dimmer product as a sub-assembly to be assembled to the housing. When assembled, the bracket support components by portions other than current carrying portions and the current carrying portions of these same components support the printed circuit board. The printed circuit board supports other components by their current carrying portions.
