ABSTRACT:
Spring apparatus is provided which includes coil springs having intermediate and end coils suitable for interconnection in order to form a continuous spring which maintains a constant load-deflection characteristic over all intermediate coils unaffected by the joint end coils. This configuration therefore finds particular utility in providing bias without compromise of sealing, electromagnetic shielding and/or conductivity.
