"PA" Series Potentiometer

For over 50 years, JANCO rotary switches from Esterline have been the first choice of the aerospace/defense industry. Now we have applied our design experience and capability to potentiometers. Our customers' need for high reliability and durability was the driving force behind our new "PA" series potentiometers. The new "PA" series exceeds all of our stringent design and operating criteria, providing you with a quality potentiometer built tough enough to handle the most environmentally demanding conditions.

Unique Combination Switch Potentiometer

This JANCO product combines rotary switches and potentiometers to save space and weight. The design approach is innovative because the potentiometer is an integral part of the rotary switch and visually appears as just another switch deck. The switch and potentiometer can be controlled independently via a concentric shaft arrangement. Prior to this design breakthrough, the only way to achieve this combination device was to piggyback a separate potentiometer onto the back of the rotary switch. This approach necessitated significant mounting hardware to hold the assembly together and some type of linkage between the two parts, impacting size, weight and potentiometer shaft play.
