Application
Detachable appliance couplers are used in office equipment, in measuring instruments, in IT environments and in medical devices, among many other types of equipment for worldwide distribution. Each appliance's power system must be adapted to the different plugs used in different regions. An appliance with a permanently-attached plug intended for use in one country cannot be readily sold in another country using an incompatible wall socket. This requires keeping track of variations throughout the life cycle of the product from assembly and testing through to shipping and repairs.
Since a country-specific power supply cord can be included in the product packaging, model variations are minimized and factory testing is simplified. Wiring of a supply cord can be eliminated in some cases, where an inlet can be mounted on an appliance's printed circuit board. Assembly and handling of an appliance is made easier if the power cord can be easily removed.
Appliances can be easily used in another country, with a simple change of the power supply cord including a connector and a country-specific power plug. When the power supply cord is damaged, it can be replaced easily, because it is a standardized part that can simply be unplugged and re-inserted. Safety hazards, maintenance expenditure and repairs are thus minimized.

Famous quotes containing the word application:
“The receipt to make a speaker, and an applauded one too, is short and easy.—Take of common sense quantum sufficit, add a little application to the rules and orders of the House, throw obvious thoughts in a new light, and make up the whole with a large quantity of purity, correctness, and elegancy of style.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“The best political economy is the care and culture of men; for, in these crises, all are ruined except such as are proper individuals, capable of thought, and of new choice and the application of their talent to new labor.”
—Ralph Waldo Emerson (1803–1882)
“By an application of the theory of relativity to the taste of readers, to-day in Germany I am called a German man of science, and in England I am represented as a Swiss Jew. If I come to be regarded as a bête noire the descriptions will be reversed, and I shall become a Swiss Jew for the Germans and a German man of science for the English!”
—Albert Einstein (1879–1955)
