single pole switch with pilot light
 
I have a white and a black in the box and am trying to hook up a single pole switch with pilot light. I've tried a few combinations but either just the switch works or just the pilot light works. How do I wire it so the pilot light comes on when the switch is on?

Sounds like you have a switch loop in the box, you will need to get the neutral from the circuit down in the box for the pilot light to work.

am I correct to say the pilot light would not work if just a switch loop? there is still no neutral

Lights always need a neutral to work.

wouldn't it work if the pilot was wired in series with the switch?

the switch is breaking the hot to the load the light is hot also but you need to land a neutral

The pilot light is a high resistance compared to the other devices....if you put it in series, good chance nothing lights up.

As noted above....you need a neutral.

No.

(Almost always) the pilot light will go on with the switch but the light or fan or whatever you are using the switch for will not.

The night light feature of a switch connects the little switch light in parallel with the switch (and that combo is in series with the fan or light or whatever being switch controlled). With the switch turned off, (usually) enough current flows through the night light to light that up but not run the fan, etc.

Some switches with lights inside can be wired up either as pilot light or night light. For the pilot light mode a neutral is needed in the switch box.

There is a big difference bewteen a lighted switch and switch with a pilot light. The lighted switch has the light, usually neon, in parallel with the switch. It lights by running a trickle current through the load when off. This is why CFL lamps will flicker on lighted switch.
