Half Hollow Shank Tungsten Contacts' innovative design of semi-hollow tungsten contacts combines light weight and high strength. Excellent performance in electrical equipment that requires compact space and high load carrying capacity, such as miniature relays, sensors, etc. Optimized heat dissipation reduces thermal stress and extends contact life.
Wu/FE
The Tungsten points are arc resistance, redectory,and less current consumption when the metal contact on surface,strong on-off current capability, good wear properties and dynamic performance hit.And its cheaper than any other metal or alloy material.
Mainly used in the electric products such as automobiles, motorcycles, electric horn, magneto etc.
