Is there any chance of getting this above switch implemented? Any reference source would be helpful.

You can create Custom switch button with the Help of image. Create a switch button (Set Alpha below to 1) and place a image above UISwitch it will work perfect.

This isn't going to be an answer to solve your question, as it is going to be more of a piece of UX advice.
This type of switch goes against Apple's HIG.
You should never display a segmented control or switch where the user will not be able to tell when the control/switch is "On" or "Off". If I were someone who hadn't used switches in an iOS application before, I would not be able to tell what's "On" or "Off" in the image above. It may be easy for you to determine this, but you need to consider the possibility of someone (with less intuition than you) using your application.
Hope this helps.
