Does anybody know where the inertia cut-out switch is on a Nissan Micra, please?
My Haynes manual doesn't mention it, though it may be useful to know.

If its an older Micra,its attached to the Fuel Tank.Its a black plastic tube with a big Ball Bearing inside.If the car flips the ball bearing moves and stops the petrol flow to the engine.Dont know about the most recent (read ugly) model!

Cut-out switches go back to the early days of fuel-injection;it was a safety requirement that the fuel supply had to cut-off if the engine stopped rotating.Most injection systems complied with this by wiring the pump relay to a signal from the distributor or equivalent.

The "tube with the big ball bearing" or similar is fitted to most modern cars and is a legal requirement-it is called a "rollover valve".It is to stop fuel coming out of the vehicle if it should turnover.

Well you learn something everyday! I didnt know that-cheers.

Thanks - if my car flips over re-starting the engine will be the last of my problems.
My 1997 Rover 100 (metro) had an inertia cut-out swith that turned the fuel off if you came to a sudden halt.
My 1997 Nissan Micra hasn't - I'm amazed at the higher Rover specifications, both in terms of build quality and equipment. It's a pity they didn't get their act together until it was too late.
