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 ...

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 ...

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 ...

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 ...
