Abstract: A shunt includes an integrally formed, continuous elongated flat plate body with two contact end portions and a curved intermediate portion which links the contact end portions and which has a constant width. The plate body has a thickness of about 1 to 2 mm and is symmetrical with respect to an axis which extends between the contact end portions. The curved intermediate portion includes at least two parallel straight segments and at least one curved bridging segment that links adjacent ends of two of the straight segments. Adjacent ones of the straight segments form a distance of about 1 to 2 mm therebetween.
