Variable units

In this category, you will find all our variable-value components for designing electrical and electromagnetic circuits.

You will discover a wide selection of products, including decade boxes (resistance, capacitance, inductance) as well as rheostats. Easy to use, they can be adjusted exactly as needed: set fixed values in your setups using our selector boxes, or observe the influence of these parameters with our potentiometer boxes.

Connect these devices to your circuits using our range of leads and adapters.
