The THUMBPOTTM is a digital voltage divider which allows the user to set varying voltages while maintaining a constant resistance within the circuit. Sharing the features and options of our 1776/1976 switches, the THUMBPOT is available in two, three or four decade models, with resistance values from 1,000 to 100,000 ohms. The main feature of the THUMBPOTTM is exact setting repeatability, with setting accuracy up to +0.05% of full scale voltage. The THUMBPOTTM is backed by a one year warranty.
