1. Switch on the source side of the load (typical):
battery > fuse > switch > load > ground
2. Switch on the ground side of the load:
battery > fuse > load > switch > ground
An illuminated switch can only work when it's located on circuit type no. 1 above.
3. Here's the same circuit as no. 2, but with an illuminated switch.
battery > fuse > load > switch > ground
iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiV
iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiibulb > ground
If your fog lights are wired like no. 3 above, the bulb in the switch won't work. Reason, the bulb creates a series-parallel path with the load (sorry, maybe getting too technical), but the load (e.g. fog lights) would use up all of the 12V.
