How is an electrical jumper made? What are the materials used and how is it assembled?
Question by elexus rex: How is an electrical jumper made? What are the materials used and how is it assembled?
I don’t exactly know how this gadget is referred to but this “electrical jumper” is being used in order to save electricity consumption if you have too may appliances at home.
I know I’m causing confusion here because jumpers are generally used in computers or as electronic testers but it is also used as power savers. Maybe I’m just using the wrong name for it. Could anybody please help me to learn how to do it?
Help! Anyone?

* In a computer, a jumper is a pair of prongs that are electrical contact points set into the computer motherboard or an adapter card . When you set a jumper, you place a plug on the prongs that completes a contact. In effect, the jumper acts as a switch by closing (or opening) an electrical circuit. Jumpers can be added or removed to change the function or performance of a PC component. A group of jumpers is sometimes called a jumper block .
The plug and play initiative was designed so that users did not have to deal with jumpers. Today, computers come with preset jumpers, although some manufacturers provide jumper settings in the instruction manual so that the owner can reset the jumpers if they want to customize performance.
In electronic test equipment, a jumper cable is used to make a temporary contact between two points for the purpose of testing a circuit.
*Typically, a jumper consists of a plastic plug that fits over a pair of protruding pins. Jumpers are sometimes used to configure expansion boards. By placing a jumper plug over a different set of pins, you can change a board’s parameters.
*A jumper is short, 10 to 50 feet and is used with a two-fer to gang two instruments together.
*A two-fer is a Y connector with one male plug and two female plugs. It is used with a jumper to gang two lamps together on the same cable.

An electrical jumper would be a wire or cable, but I do not know how it could save electricity consumption.
