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 ...

Safety switches are a type of sensor commonly used to ensure safe operation of a variety of machinery types. Non-contact safety sensors are an option when precise guidance of protective devices is ...

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 ...
