ABSTRACT OF THE DISCLOSURE A contact spring set is described which includes contact springs and a lifting card that is disposed at the outer ends of the contact springs and attached between an upper return spring and a lower return spring. In order to secure the lifting card to at least one of the return springs without introducing any play between the secured parts, the return spring is made flat and is provided with two pairs of tabs which are bent so that adjacent tabs point in Opposite directions. This arrangement provides a simple fitting of the lifting card: the lifting card has a hole which is adopted to receive the return spring. The hole includes two portions, both being substantially equal and displaced relative to a line of symmetry through the center of the lifting card which is perpendicular to the plane of the return spring. The contour of each hole portion has at least one straight side, the straight sides being parallel and spaced apart a distance corres- ponding to the thickness of the return spring with a combined overall length corresponding to the width of the return spring. The hole portions are configured to allow the first pair of tabs to pass through freely but, when pushing the card further on, the return spring is forced to twist to allow the second pair of tabs to pass through. After completed passage of the tabs the spring flips back and locks in the hole with a tight fit.
