You've likely done no damage. I've done it several times in my life (not purposely) without any ill effects. It's recommended by the manufacturer not to change lenses with the camera on. Some claim this attracts dust to the sensor. It could also cause issues with the contacts possibly causing erratic behavior. All in all, try not to do it again, but I wouldn't lose any sleep over it.

I agree with rj: it is a bad idea to do that, but not at the level of dropping your camera from the top of a building onto a concrete pavement.

I've done it several times also with no ill effects. The camera could lock up or work erratically however a power off then on usually resolves these issues.

I'm sure the engineers considered this when designing how the electrical contacts were laid out otherewise they would have designed an interlock to prevent removing the lens with power on.

It happens to me on occasion. Once or twice, I have noted the camera not functioning quite right after. Turning it off and back on has cured the problem each time.

It is not recommended, but appears not to damage anything, so far.
