ISO: 120vac Sliding linear contacts
(OP)
Hi there!
Today I've been trying to hunt down some sliding linear contacts. I'd like to find a retail example of some pretty straightforward designs capable of operating on standard US line voltage. So far I've been surprised with my lack of options and I wonder if it might be due to a fundamental inadequacy of contacts used in this way. I have seen some similar barbed "taps" used for landscaping which pierce the insulation, but I wonder if a sliding arrangement exists.
Thanks for any info!

The track lighting examples I've seen have been for DC powered lights except for the half-turn socket type installations. Also, those have been 2 conductor rails, and I would guess we would want to have a grounded solution.

As you said I HIGHLY doubt an insulation piercing "re-positionable" connector exists as I'd expect UL to poo poo it in a second (and they should)
Good luck.. Time for compromise.
Sounds like you are dead set on a cord solution versus a track.. If so I'd be looking at having multiple/various length pluggable wire links. Like rope lighting I guess where the customer could cut/install the plugs themselves. Or build the insulation piercing into the actual fixture.. Cut a length of lamp cord and snap it into the fixture and you are done.. Ever need to move it simply rip it out of the fixture and cut a new lamp cord section.

220V Power Cable for temporary lighting & Xmas tree light strings, & has a system of lampholders with pointed contacts that pierce thru the insulation & into the 2.5mm stranded conductors.
It meets the South African Codes of Practice.

Could you use a flexible channel cable tray/trough similar to what's used in elevators and computer printer heads (sort of)?
I'm picturing a fixed-length cable in a segmented, flexible carrier that moves along a linear range of positions.

Mike: That is the 1st time I've encountered something like that, and its also a great suggestion. I'm going to read up on that in more detail and include the example in my presentation, thanks!

Google Winkle Industries - Crane Downshop leads.
Regarding my other suggestion I will attempt to get the trade name of 'figure 8' system

The fixture could slide along a track for purely mechanical purposes. The cord could pay out from the reel inside the fixture into the track (for protection and concealment).
