Aluminum to Copper Wire Connectors, Copper to Aluminum Wire Connectors with 2 Port, 10 Pack

I'm totally blind. I got these for use in my house being I have that type of wiring and it is ahrd to find switches and the like for it. These have came in handy for people to help me swap out switches and to also put in a few ceiling fans so it is done correctly. Most switches and all ceiling fans are for copper wiring. This away I know things are done correctly and will also meet code when I go to part with the house. These will handle two wires one of each type that you screw down. Then you flip close the lid on them. That is all that is two them. Just had to do that a week or so ago. swapped out a switch for a old fan that was half and half. Power wire was the old wire and the Copper wire went up to the fan. So had to add a pig tail to make it copper so it could be screwed onto the switch being the old switch was for a 30 year model of fan to be able to control it. The new fan wouldn't work with it, so put in a standard Off/On switch.

Probably best way to join copper and aluminum wire short of rewiring the screw wells allows copper and aluminum to be independently connected without joining the dissimilar metals and corresponding problems and hazards

Buy the real thing Alumiconn made by King Innovation--also available on Amazon.These are no good! When you tighten them, the slot in the screw chips off.

These are to refill my parts drawer since I used up the last ones putting up 4 light fixtures this last month. They are not nearly as messy as that gray pooky that gets on everything. These also handle connecting different size wire gauges to each other much better than the screw-on nut caps. These are larger than the nut caps, so they may not work with large switches in small/shallow boxes.

Easy to use exactly what was needed. Added copper pigtails from aluminum main wire to switch for light to eliminate problem of loose connection from aluminum wire expanding and contraction.
