I put strip LED lights under all the wall cabinets, so they put more light directly down on to the work surfaces. I wired them all together in a junction box, connected a rocker switch under the cabinet, and ran a cable up to the top and along to the double receptacle for the microwave.

Then I did the same with upward-facing LED strip lights along the top of the wall cabinets..... and connected them to the same double rocker switch under the cabinets.

Whole set-up uses standard electrical connectors, boxes and switches, but is still a "plug in" set-up, consistent with the strip lights design as plug in fittings.
