Abstract

A battery contact spring with a spring body manufactured as a flexible wire part is disclosed. The battery contact spring has a first contact head section for contacting a first battery; a second contact head section for contacting a second battery, and at least one first spiral spring section that extends between a spring foot area and the first contact head section and which flexibly supports the first contact head section. The spring body is designed in such a way that a coil end of the first spiral spring section opposite the spring foot area crosses over into the first contact head section and attached to this first head section is a connection bridge that crosses over into the second contact head section.
