This construction can be furnished Resistance Taper with one end terminal at either end of the resistance Standard: Linear taper element or with terminals at both ends of the element. Insulated Construction The contactor is insulated from the Incorporated Fixed Resistor base and connected to the center terminal on the insulated A fixed resistor can be incorporated in the Series 115 construction. This construction can be supplied with the at the end of CW or CCW rotation to a minimum of 15% center terminal and one end terminal at either end of the of the total resistance value. The rotation is shortened resistance element or with the center terminal and terminals by an amount proportional to the ratio of the fixed resistor at both ends of the resistance element. to the total resistance value.
