Rotary switches are electromechanical components that allow users to select different electrical circuits or functions by rotating a knob or shaft. They are commonly used for selecting multiple positions or settings in electronic equipment.

Elma provides a wide range of rotary switch solutions including selector switches, coded switches, encoders, multifunctional switches, and audio rotary switches, along with compatible knobs and accessories.

Rotary switches are widely used in industrial controls, medical devices, audio equipment, and test & measurement systems where precise manual input and reliable switching are required.

Many Elma rotary switches feature durable materials, gold-plated contacts, and sealing up to IP68, providing protection against dust and water while ensuring long-term reliability.

A coded rotary switch outputs a digital code (such as HEX, Gray, or BCD) for each position, allowing electronic systems to detect the selected setting accurately.
