Courtesy switch mounted in door on handle

Does anyone have a picture or a diagram of the switch mounted to the door handle that controls the courtesy and overhead console lamps? I'm thinking the one on my driver's door may be getting flaky. Lights always come on when I use the fob to unlock, but they don't always come on if I just open the driver's door with the handle. Passenger door seems to work fine.

Thanks,
