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 ...

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 ...

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 ...

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.
