1. A method of stamping and forming planar sheet metal stock to make an electrical terminal including the following structure:
- a terminal base portion lying generally in the plane of the stock; and
a generally U-shaped contact section connected to the terminal base portion and including a bight portion and a pair of opposed and spaced apart leg portions extending from the bight portion, the bight portion lying generally perpendicular to the plane of the stock, a first of the leg portions lying generally in the plane of the stock and a second of the leg portions lying generally parallel to and spaced from the plane of the stock;
said method comprising the following steps;
stamping the stock to define a terminal blank including the terminal base portion, bight portion and leg portions all lying generally in the plane of the stock;
forming the blank to make the contact section by leaving the bight portion generally in the plane of the stock, moving the first leg portion and at least part of the base portion to a position generally perpendicular to the plane of the stock and moving the second leg portion to a position generally perpendicular to the plane of the stock and spaced from the first leg portion; and
rotating the contact section by returning the base portion generally to the plane of the stock.

Abstract
An electrical terminal having a portion of a contact section overhanging the plane of the stock is made by a method that does not weaken the terminal by the use of a slot or similar structure. A blank is stamped from sheet metal stock. Portions of the blank including the portion to overhang are formed up from the plane of the stock. At least part of the terminal base is formed up from the plane of the stock. The formed base portion is returned to the plane of the stock to rotate the contact section and move the overhanging portion to its final position.

8. A method of making an electrical terminal from planar metal stock comprising:
-
stamping the stock to define a blank having a terminal base portion and a contact element that will overhang the plane of the stock; forming the blank to move the base portion and the contact element up from the plane of the stock; and returning the base portion to the plane of the stock in order to move the contact element to an overhanging position.
