When looking at a form element styled to look like a flick switch but that actually behaves like a clickable element, how likely is the user to realise that they can click the element to switch it, rather than use the much more cumbersome click - hold - drag - drop interaction that is implied by the fact it looks like a flick switch.
Has anyone examined this in tests to see how easily users work out that they can just click ?

EDIT ...
From the answers given I think that in some ways my question is unclear and the point has been missed. I'm not asking whether or not users can work out whether they can interact with it, or whether they can click it, but how easy is it for a user to work out they can click when the interface element doesn't look like something you click.
It would be good for example to know what % of users when faced with this interaction element attempt to click it to activate it rather than hold and slide it. I would hypothesise a very small % but would like to see what evidence there is for this hypothesis
