Alan Vincent, Sales Director of Foremost, said: “The market for compact robust electromechanical HMI products offering operators safe and simple operation and direct tactile feedback continues to grow in industrial and vehicle systems. While touch screens are increasing in popularity as an HMI solution, they are not always suitable for noisy, harsh environments or when operators may have to wear protective clothing such as gloves. The new Elma MR50 multi rotary switch offers a compact, rugged, flexible control product.”
