Fuel cut prevents the fuel pump from energizing. A switch is wired in series with the fuel pump power wire. The switch opens or closes the circuit.

Re: fuel cut? and what does it do? (eda6)
well, that is one type of fuel cut.
another type of fuel cut is controlled by your ecu. the ecu senses that your exceeding the rev limit or speed limit set in your computer and tells the injectors to stop firing. your car leans out and "stumbles" and then when your car goes back down below the set speed or rpm, it starts firing the injectors agian.
i think there might be things like "fuel cut defenders" that splice a box between your ecu and your engine, and tricks your ecu to not hit fuel cut. that might not be a good idea though because you might lean out at high rpms.
in the honda world, if you want to get rid of fuel cut you can get your ecu reprogrammed by any one of many people on honda-tech. or chip it yourself. you wont get a switch, but your engine wont barf at high rpm.
it might not be a good idea on a stock setup though. most engines make power up to its programmed fuel cut point, and no more. i know the d16a6 makes power right up to the 7200 fuel cut point, and i think even a little beyond that to like 7800 or so, but beyond that its bad news, unless you have a setup that can handle it.
