The only dimmer switch that I'm familiar with requires to be turned down all the way before it switches off (it's a knob going from 0 to "dimmest" with a click when turned anticlockwise, and then gets brighter as you turn it further in that direction).

I would think that the dimmer switch would last better if just clicked.

Also, if just clicked, the lightbulb would be on for slightly less time (you'd switch it off almost instantly rather than taking 2 seconds to do so), and would therefore use less energy. That's the only apparent difference in energy use that I can see.

That's the sort I'm most familiar with too. I've seen the other sort (both ones with a conventional switch and ones where the dimmer knob clicks in and out) but have not used them. Although I suppose the weird panel switch I used to have in Cardiff counts. With that you either tapped it on and off or pressed gently to dim/undim. I have to admit to tapping it on and off because it was easier. A short tap worked whereas to do it gradually you had to make sure you didn't touch it too hard to start with. The really shiny thing about that light switch though was the remote control!
