EAO supplies illuminated rotary switches designed for demanding industrial applications and public transport systems. These solutions are designed for convenient operation, high resistance to intensive use, and good signalling visibility under different operating conditions. The switches are available with single- or dual-colour LED illumination, improving readability and user comfort. Their ergonomic shape and clearly perceptible switching positions provide confident operation even in demanding environments. Modular construction and durable components contribute to long service life and stable operation in industrial and railway applications. Bright LED illumination ensures good visibility of the controls both in strong daylight and in poorly lit areas.
