Is anyone familiar with the above subject? My brother-in-law who lives in PA told me he is having problems with push button light switches that are broken along with problems with a wall receptacle that needs replacing. Wiring in these systems used low voltage wiring ie: 3 conductors, red, black, yellow. Are parts available for these old systems?
I was surprised to hear of such a system. His appliances are run on regular AC lines.
If not any options before running new lines?
