We are offering dc potentiometer. The precision dc potentiometer type - 9408 has been designed to provide the highest standards of accuracy over a period of many years without any maintenance, whilst at the same time allowing rapid and easy operation. The most outstanding contribution to the development of potential meters in recent years resulted from the introduction of the unique vaiseshika low resistance precision instrument switch, used through out the precision dc potentiometer. Vaiseshika.com is available for more details. this switch was developed after several years of research into the fundamental factors affecting contact resistance. The stationary contacts are silver clad copper bars, mounted in a robust insulating frame. The brush, which is composed of several contact springs, each of which is independent of the others and is unrestricted in its movement, makes a bridge contact between adjacent bars in a symmetrical manner. As a result, low and consistent contact resistance is achieved without high contact pressure or mechanical wear. After a life test of some 20, 000 operations, the switch was still mechanically sound and its stability had actually improved in the narrow range specified. The over all switch resistance is approximately 0.001 ohm and the variation of contact resistance is less than 0.0001 ohm.
