I need the wiring diagram for a Cooper 277W single pole switch with pilot light. The light is to be on when the switch is on. Thanks!

change the switch

The Cooper combo device requires neutral wire to energize the outlet.
To control outlet with switch, the Hot side of device must have break-away fin.
Remove break-away fin.
Connect jumper wire from switch load side to outlet Hot side.

Some of your wiring does not sound up to code.

1) Two differences between regular switch and cooper 277
-Different color screws: Regular switch has two brass screws, and either wire can connect to either screw. Cooper 277 has dark, brass, silver screws, and hot wire connects to dark screw, and wire to light connects to brass screw.
-Cooper needs neutral wire connected to silver screw, to power the indicator light.

2) Some of the wiring in your box does not sound up to code.
Bare ground wire should not be connected to black and white wires.
Electrician should check this out.
Probably the ground wire is being used as a Neutral. Bare ground wires and white neutral wires both connect to neutral busbar at main breaker box.

Wired as shown in illustration, the pilot light and the Load will come on each time switch is turned on.
The illustration show Load is light bulb.
In your case, the Load will be an outlet instead of light bulb.
So the Load will have 2 wires. The black wire from switch connects to brass screw on outlet. The neutral connects to silver screw.
Bare ground wires connect to green screws.

Wiring is suspect.
Black hot wire connects to dark screws.
Break off tab should be intact.
White neutral wire connects to silver screw.
Wire going to switch load connects to brass screw.

I made following diagram based on Cooper pilot light instruction sheet:
Neutral wires are usually the white wires that are twisted together in back of box and covered with wire nut.
If your box does not have neutrals, you can also connect bare ground wire to silver screw until you have time to run neutral wire to box >> ground to anything but ground screw is not code and not recommended.

recheck the wiring in receptacle loose wire --broken wire / connection or improper wiring

Hello,
If the wiring for the night light is internal then you can not change it...
If the wire is external then all you need to do is move the hot (black) wire that feeds the light from the black feed wire to the black wire that goes to your fixture so that it is now switched....

Hope this helps

Depends on whether you want the pilot to glow when the circuit is live (the main light is on) or to glow when the circuit is off. (The switch can be used either way, and I have used this switch in both configurations at different places.)

The wiring diagram is on the inside of the box.

In indicates that if you want the pilot light to glow when the circuit is off, then you only need two wires (the live and the return, usually colored black and white, respectively). However, you also need a ground. The instructions say that you need the ground for safety (and probably legal code) reasons, but I suspect that, without the ground, the pilot light won't work in this configuration.

However, if you want the pilot light to glow when the circuit is on, you probably need a three wire configuration (plus the ground).

Hope this helps.
