Vaiseshika Electron Devices manufactures Precision DC Potentiometer. Vaiseshika Electron Devices Quality Management System is ISO 9001:2000 compliant. 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. It allows rapid and easy operation and includes the Low Resistance Precision instrument switch, used through out the Precision DC Potentiometer. 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. The over all switch resistance is approximately 0.001 Ohm and the variation of contact resistance is less than ± 0.0001 hm.
