It the black plastic bit under this metal bit. The switch is a tiny round thing.

to test if its working hold the throttle open over 2.5k rpm with your hand. then with your other hand push & hold the switch to close it. you should hear the diaphram operate & engine rev's will drop about 1k rpm before bouncing back up. it will bounce for as long as you hold the switch

this tell you the switch is functioning!

But what does it actually do?

I saw it and assumed it just sent the engine into some "nutcase mode" when you want all it can give. I can tell you it will drink a tankfull in about an hour flat out, but I'm not so sure it's all that switch's fault.

On a 16v (and early 8v K-Jets) there is an idle switch which tells the engine to reduce the fueling and run in idle mode.

On a digifant MK2 (like yours according to your sig) There are 2 throttle switches, the idle switch underneath which tells the ecu the engine is idling, and a wide open throttle switch on top whihc tells the ecu you're going hell for leather so it chucks more fuel in :grin:
