Patent ID: 8021168

Claim:
A contact spring having a free contacting end for making electric contact between said free contacting end and a contact surface, the contact spring comprising N metal contact-spring lamellae and N−1 spacer elements where N≧2, the metal contact-spring lamellae being held fixed in a clamped region with one spacer element between each two adjacent metal contact-spring lamellae, being spaced apart from one another in a resilient region, extending parallel to one another in a freely and resiliently flexing manner to the free contacting end, and ending in a common plane at the free contacting end, the metal contact-spring lamellae including in the resilient region at least one bend at each of which there is a predetermined angle between an upstream longitudinal axis which the metal contact-spring lamellae have upstream of the bend and a downstream longitudinal axis which the metal contact-spring lamellae have downstream of the bend, said metal contact-spring lamellae spaced apart from one another by the thickness of the spacer elements in the resilient region and at least one of the metal contact-spring lamellae including at least one slot starting from the free contacting end.
