Formula one clutch question

I ahve a fairly decent idea of how an F-1 Sequential gearbox works but i would like to know how the clutch works. I'm pretty sure it is electronic but how long does it disengage for? Does the engine cut ignition while the clutch is disengaged? Why doesn't the car jerk when the clutch re-engages (maybe it does but clearly not enough to shake the rear tires loose)?

any information would be greatly apreciated. i did some searches but didnt find the info i was looking for.

yes, the engine delays ignition while the clutch is engaged. While they're in the pits he can hold a button to engage the clutch while the car is on the jacks

The typical F1 clutch har a diameter of less than 4", it has around 4 plates of carbon/carbon and is otherwise constructed from titanium. It's pull operated and is placed directly on the engine or on the gearbox. The clutch is operated just like the gearbox, that is with the electrohydralic systems the F1 cars use.

The gearbox has typically 7 forward gears, all employing "dogs". The clutch is only used when starting from standstill, gearchanges are done with the clutch engaged.

Today the clutch is operated "manually", earlier when you started it was just to push a button, give full throttle, release the button and off you go. The only thing one had to do was to steer.
Today the clutch is controlled with some sort of paddle on the steering wheel.
