The key to the superb quality of this spade lies in the patented sandwich design of its contact fork. Elastomer oscillation dampers eliminate airborne noise and mechanical vibrationsThis ensures almost total suppression of contact microphonics and there is no interfering ancillary noise. The sandwich design of the contact forks with elastomer inserted in a steel cap generates high and uniform contact pressure while minimising transition resistance. The quality of signal transmission is markedly improved, particularly with high currents or small voltages. 

The WBT-0661 has a fork width of 6mm (internal dimension).
The WBT-0681 has a fork width of 8mm (internal dimension).
