As time goes on, there are more and more switches being developed and manufactured across the world. Some are by new manufacturers, some are collaborations between companies and manufacturers, and some are consumer made.
Mechanical keyboards (or mechanical-switch keyboards) are computer keyboards which have an individual switch for each key. The following table is a compilation list of mechanical keyboard models, brands, and series:
Many switch designs use gold for contact material to prolong the lifetime of the switch by preventing switch failure from oxidization. Most designs use a metal leaf, where the movable contact is a leaf spring. A major producer of discrete metal contact switches is Cherry, who has manufactured the Cherry MX family of switches since the 1980s ...
Five-pin male 180° DIN connector from a 1988 Schneider MF2 keyboard by Cherry. The DIN connector is an electrical connector that was standardized by the Deutsches Institut für Normung (DIN), the German Institute for Standards, in the mid 1950s, initially with 3 pins for mono, but when stereo connections and gear appeared in late 1950s (1959 or so), versions with 5 pins or more were launched.
M12 A-coded 5-pin connector: For each connector size, the A-coding is the inspecific pinout variant and the only variant defined in varying numbers of pins. Ethernet cable with an M12 X-coded connector in one end and a modular connector in the other.
According to a USB-IF chairman, "at least 10 to 15 percent of the stated peak 60 MB/s (480 Mbit/s) of Hi-speed USB goes to overhead—the communication protocol between the card and the peripheral. Overhead is a component of all connectivity standards". [1] Tables illustrating the transfer limits are shown in Chapter 5 of the USB spec.
If at first — or second, or third — you don't succeed, try, try again. San Francisco's Jake Moody missed three field goals Sunday afternoon against Tampa Bay, but made one that he needed to ...
Pin-to-pin compatible devices share an assignment of functions to pins, but may have differing electrical characteristics (supply voltages, or oscillator frequencies) or thermal characteristics (TDPs, reflow curves, or temperature tolerances). As a result, their use in a system may require that portions of the system, such as its power delivery ...
