Potentiometer / rotary switch drive from Schlegel
Rotary switch drives are needed in order to control the speed smoothly, and to set temperatures and voltages precisely using the potentiometer. The drives are used in electronic devices and industrial equipment and must also work under large temperature fluctuations and be insensitive to penetrating moisture and dust. We offer drives for rotary switches and potentiometers from Schlegel.
What is a potentiometer / rotary switch drive?
So that rotary potentiometers can be operated, drives are needed for rotary switches and potentiometers. These specific controllers are characterised by a rotary control knob. Depending on the intended use, there are potentiometer and rotary switch drives that can be controlled smoothly or in steps.
How does a potentiometer / rotary switch drive work?
A rotary switch or potentiometer drive is a switch that is needed in order to control the resistance / current flow at a potentiometer. Each rotary movement moves an axle, which is connected to the potentiometer or a multiple pin rotary switch.
What is a potentiometer / rotary switch drive needed for?
Whether in measuring devices, in industrial systems or to control the volume of an amplifier: the range of application areas of rotary switch and potentiometer drives is large. Depending on the area of application, the drives must be able to control a potentiometer smoothly, in steps, roughly or precisely.
How is a potentiometer / rotary switch drive connected?
Both drive forms are connected to the switch or potentiometer via an axle. Rotary switch drives typically have axles with a diameter of 6mm and a length of 32mm or 50mm.

What types of potentiometer / rotary switch drive are there?
Our range of Schlegel drives includes circular and rectangular models, for either rectangular or circular installation openings.
