If so, they'll probably say so on the bottom with some words like "transient protected", "diode installed", etc. If in doubt, it doesn't hurt to install your own diode outside the contactor. Two diodes is fine, no diodes is really hard on your switch. Bob . . . ________________________________ Message 3 _____________________________________ Time: 09:52:09 AM PST US From: "Robert L.

Unfortunately, difficult to acquire in small quantities. Back in my younger days, my local electronics supplier had a room full of racks holding spools of wire specific to the electronic arts. One could select from a variety of products and purchase any length priced by the foot. Today, I have no known suppliers offering a similar service. I can buy 100' spools by mail-order . . . sight unseen. In other words, I can't 'test' the wire for feel, appearance, physical characteristics before I have to buy many times more wire than I need to do the job. I've been pondering your question and have the following suggestion. In my grab bag of cable assemblies I'm seeing a family of USB cables that seem to offer a solution to your problem. They're small in diameter, flexible, plenty of conductors and shielded. Further, USB cables are like rabbits put a few into a box for 'future use' and in a year or so, they've multiplied in number exponentially. Emacs! Try this wire on one of your target headsets as an experiment. They're 4-conductor + shield. Very flexible, reasonably robust. You can parallel extra conductors or simply ignore them.

These tend to be less flexible and most use solid conductors. Good wire for situations that do not have to be coiled/uncoiled and moved around.

I think his headset cables would call for 5 conductors. Two floating for phones. One for PTT, one for MIC HI and the shield conductor for MIC LO/PTT LO. Your point is well taken. Certainly other manufactured audio/video/signal cables should be considered as sources for short lengths of specialty wire. The bill of materials cost for mass manufactured assemblies is usually a small fraction of the cost for one-of-a-kind DIY assemblies. If you can get the cables out of the orphaned hardware box of a thrift shop, they can approach 'free'. My dad used to run a lumber yard and sold some kinds of wire, chain and liquids from 'bulk' that was harvested from manufactured products For example, a 100' 10-3 extension cord with ends already installed was less expensive than a 100' spool of the same wire. The guy selling cords bought wire at carload lot prices. The guy selling you wire on a spool charged 100' lot prices. Same thing with chains and paint-thinner/charcoal lighter. Dad bought cords, cut the ends off and spooled it up for cut-length sales.
