Spring contact fingers are suitable for various tolerances, mainly reflected in the following aspects:

-Adaptability to different sizes: The size of the spring contact fingers and the number of independent coil turns make it suitable for various electrical contact designs. Different application scenarios may require spring fingers of different sizes to achieve optimal contact effects. For example, in some small electronic devices, small spring fingers are needed to adapt to limited space; In some large power equipment, larger sized spring contacts may be required to carry larger currents.

-Compensation ability for shape deviation: When the spring contact finger is compressed, each coil will deform individually. Regardless of which part of the coil deforms, the entire spring will react, achieving consistent load at each contact point. This characteristic enables the spring contact fingers to compensate for the shape deviation of the contact surface, ensuring good contact under various surface shapes.

-Tolerance for assembly errors: In the actual assembly process, there may inevitably be certain errors. The unique structure of the spring contact finger allows it to tolerate these assembly errors to a certain extent while still ensuring reliable electrical contact. For example, when there is a certain deviation in the assembly position of two components, the spring contact finger can adapt to this deviation through its own deformation, thereby maintaining the stability of the contact.
