Abstract: A contact module with connectors adapted to engage with first and second electrical conductors such that when resiliently interfaced with the conductors there is a net zero moment of inertia exerted on the conductors. Each individual connector exerts a resilient spring force to engage with an electrical conductor. When such resilient forces, as in the prior art are aggregated, they can exert a considerable vectored moment of inertia on the electrical conductors to which they are connected. The connectors of the present invention are arranged so that each individual connector has an opposing connector somewhere in the module to offset each individual moment of inertia so that the net sum of all moments on the interfacing electrical conductor is zero.
