Ok, so my house does not have neutral wires at the switches. I know there are switches that will work without neutral, but they are for incandescent bulbs. I believe, if I understand correctly, that these work with incandescent and not LED because there is always a small amount of power in the circuit to keep the switch awake. This small amount of power is enough to keep an LED lit, but not an incandescent.
Now, my question is this… I have a single circuit in my bathroom with a switch. On this circuit is 3 A19 LED, and a bathroom fan. Would one of the non neutral switches work in this situation as it takes much more load to turn things on in this circuit compared to one with a single LED bulb?
