Bonnet open warning sign

After picking up my new 55 plate 2.0 Ghia two weeks ago I was having a look under the bonnet and decided to spray some WD40 into the keyhole in the grill and around the catch as it felt slightly stiff and I didn't want any problems.

Well I got a problem straight away! Now my dashboard warning is constantly lit saying "bonnet open". Unless it's a coincidence it seems to be my fault for spraying in WD40. 

Does anyone know the where the control switch telling the car that the bonnet is open is located? If so how can I get the light to go out? I did read about electrical contact spray being great for cleaning these sort of things, I have bought some but have no idea where I should be spraying it.

Any ideas you clever bunch?

Dave.

The one that sits upright vertically?

I thought it was that tbh but mine seems to be stuck solid that's why I wasn't sure that was it. 

Should I spray electrical contact cleaner down into the switch to try to clean out the WD40?

Just spayed electrical contact cleaner into and around the bullet switch and worked the switch free so it's now moving, although it does look a bit rusty,and I still have the light on. 

Is it a new switch? It looks like it's all part of the lock mechanism and can't be bought separately. Or is there a way of bypassing the switch altogether?

Just cleaned the rust off the bullet switch and sprayed again but no luck.

Is there a way to short the connector so that the system thinks the bonnet is closed all the time? I looked around the lock assembly and can't see any wires leading to the switch itself.

It's just annoying seeing the red warning light on constantly and the bonnet open sign keep popping up.

Following on from my first post. 

Because the switch was saying bonnet open and my alarm hadn't gone off in the two months I've had the car I assumed the alarm wasn't working on the car. I checked the oil on Sunday and when I opened the bonnet the alarm went off. It hasn't done that before and logic would tell me that the alarm should be going off all the time if the switch indicates an open bonnet surely? 

I'm puzzled!

Is the switch actually making contact with the bonnet, get someone to press the switch while you watch the warning light.
