Foremost Electronics offers the new Elma MR50 multi rotary switch. Rugged rotary switches have many industrial applications and are indispensable in the agricultural vehicle sector, where they are subjected to extremely harsh conditions.


The switch is a very small yet robust, multifunctional rotary switch offering the highest functionality and performance in a minimal space for compact control panels and portable devices. Front panel sealing to IP60 and IP68 and giving outstanding vibration resistance, the series is an excellent rotary selector for building site machinery and vehicles and agricultural applications.


The series is highly customisable and has been employed in applications as diverse as target aiming devices, night vision devices, two-way radios, interface solutions, cockpit applications (aircraft, automotive, construction machines, defence vehicles), portable devices (communication, medical, rescue, sports, transportation, measuring, photo/video and test equipment.


With a diameter of just 1/2" (12.7mm), the device provides up to 16 switch positions, with switching torques of up to 6Ncm, and works in either shorting or non-shorting mode. With gold-plated contacts (3-micron gold), the switch performs over the operating temperature range of -45C to +85C.


Alan Vincent, sales director of Foremost, comments: “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.”
