Eh? Do they need to be dimmers? Switches usually don't much care about the load (within reason).

Not dimmers, but switches with pilot lights which are on when the switch is off. I guess the lights in the switches require a little current flowing through the main circuit, because Leviton says "not for LED or CFL bulbs". That's why I'm asking here! They also say "doesn't require a neutral" so maybe there is one which does require a neutral. The particular circuit I'm trying to control is a ceiling fan circuit, which is remotely controlled, so I guess when the wall switch is on but the remote has told the fan and light to be off, the only current flowing through the closed switch is that used by the fan's receiver, and that's not enough to power a small light in the switch.

This lutron one is apparently fine with LED lights. (I have no personal experience with it)

Lutron Claro

"The particular circuit I'm trying to control is a ceiling fan circuit, which is remotely controlled..."

The fan has its own remote control to turn it on and off, adjust the speed, and control the LED light? I would think that there should always be power to the fan so the remote will function. If power is removed from the fan other than by the remote, does the fan "remember" the last state of the fan (on/off/speed) and LED light? Even if so and the fan was off via the remote, wouldn't it be weird to turn on the wall switch and not have the fan start up? I might remove the wall switch, connect the wires together permanently with wire nuts, and put a blank cover over the electrical box -- leaving all control to the remote.

I have Lutron Decora switches in my bathrooms. Luckily the LED lights cant read the instructions and they work fine.

wdccruise, My fans always work as previously set by the remote, then I turn them on. I really don't like using the remote. I much prefer the wall switches. This is true for both brand of DC motor fans I have, Harbor Breeze and MinkeAire.

weedmaster, I didn't look at Lutron, I just looked at the Leviton selection and all that I looked at said for incandescent lamp use only. My thought is that since they don't require a neutral line, they must work by putting a small light inside the switch in series with the rest of the circuit, and if the rest of the circuit has too high a resistance, the light won't work.
