I wanted to add a remote transmitter to my ceiling fan and the correpsonding wall switch. When removing the current switch (dual slider fan/light), I have five wires in the switch box. There is a blue wire that powers the light. A orange wire that powers the fan. There are two black (cloth wires twisted together); one of these is hot and the other is not--and ground. New switch only has two black and ground. (Current switch was wired as follows: Black from switch to both cloth blacks. Red from switch to blue. Yellow from switch to orange.) Confused how to wire new switch with only two blacks and ground. Thank you!!
The non-live black braided wire is not neutral. Wires are not neutral simply because a voltage tester doesn't light up. The non-live black is onward always-hot. It became de-energized because you disconnected it from supply when you separated it. I trust you did not do that hot :)
Take the blue wire out of service. Cap it off at both ends. Tape the cap down (they fall off single wires otherwise). That's the only time you ever tape a wirenut.
The LINE/SUPPLY black from the new switch joins the 2 cloth switches.
The LOAD/TO-FAN black from the new switch joins the one unattached wire (red).
Up in the fan, connect the fan controller to red and neutral.
