Insufficient spring pressure causes high contact resistance, leading to overheating, voltage drop, contact welding, and premature failure due to arcing and oxidation.
Inspect during routine maintenance every 6-12 months or per manufacturer recommendations, checking for deformation, corrosion, loss of tension, and contact wear.
Yes, but must match original specifications for spring rate, material, and dimensions to maintain proper contact pressure and alignment within the assembly.
