What is Louver_tron contact band and what are the benefits of multiple contact points in a connector?

The basic common principle of all Louver_tron contact strips is to provide multiple contact points in a relatively dense arrangement of consecutively sprung contact elements, arranged in parallel.

Louver_tron is a product family within the weftron product range of different electrical contact band or electrical contact strip designs.

The design differences within this product range of contact bands with multiple contact points are in the physical width and thickness of the contact bands as well as in the features of the individual louvered contacts or lamellar contacts. The basic common principle of all Louver_tron contact strips is to provide multiple contact points in a relatively dense arrangement of consecutively sprung contact elements, arranged in parallel.
In absence of a defined technical term, the individual sprung contact elements are commonly compared with similar looking technical elements. Hence also referred to as lamellar contacts, louvered contacts or contact bridges. In the final application, when functioning as multiple contact points between two conducting surfaces, these multiple current paths have significant advantages over contact systems with less or with only two current paths.
Any contact system and hence any connector will cause a certain resistance in an electrical system. In critical and demanding applications it is essential to assure the least restriction to current flow.
So the main design inherent advantage of Louver_tron louvered contact band is easily explained with Ohm’s law. In a system of electrical resistors arranged in parallel, the total resistance is a function of:
(average resistance per resistor) / (number of resistors)
In the case of the Louver_tron contact band with its parallel multiple contact points arrangement, the total resistance of a contact system using Louver_tron is:
(average contact resistance per louvered contact) / (number of louvered contacts).
