Asperities: Mass-produced switch contacts have an rms roughness ranging from 0.5 to 1 10 6 in. These "smooth" surfaces, in reality, comprise microscopic peaks and valleys. As a result, two mating ...

Nanoelectromechanical (NEM) switches are similar to conventional semiconductor switches in that they can be used as relays, transistors, logic devices and sensors. However, the operating principles of ...

Limit switches: A mechanical limit switch interlocks a mechanical motion or position with an electrical circuit. A good starting point for limit-switch selection is contact arrangement. The most ...

Honeywell announced it has expanded its Limitless™ Wireless Solutions portfolio with the introduction of its new Limitless™ Non-Contact Switch WLS Series. Honeywell has expanded its Limitless™ ...

Modern industrial systems have a multitude of sensors, switches, buttons and other low-frequency inputs that need continual monitoring. The network of input devices that an industrial system (such as ...

Why designers are rethinking their extreme reliance on touchscreens for the user interface. The features that are especially desired in tactile switches, in addition to basic contact closure/opening.
