A buckling spring is a type of keyswitch mechanism, popularized by IBM's keyboards for the PC, PC/AT, 5250/3270 terminals, PS/2, and other systems. It was used by IBM's Model F keyboards (for instance the AT keyboard ), and the more common Model M .
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 ...
The popularity of the IBM PC and its successors made the Model M's design influential: Almost all later general-purpose computer keyboards mimicked its key layout and other aspects of its ergonomics. The layout was standardized by ISO in 1994 and ANSI in 1998, with minor additions—most notably the Windows key and Menu key .
Switch access is the use of one or more switches to operate computers and other devices and is primarily used by people with severe physical or cognitive impairment. A switch is an assistive technology device that replaces the need to use a computer keyboard or a mouse. It may allow users to control a computer, power wheelchair, video game ...
Most accordions have automatic or preset switches, similar to voice selection on an electronic keyboard, or (more precisely) to a preset combination action in a pipe organ. These switches control which reed ranks are enabled (opened up) or disabled (closed off): some switches enable a single reed rank, others enable several simultaneous reed ranks.
The soundboard, depending on the instrument, is called a soundboard, top, top plate, resonator, table, sound-table, or belly. It is usually made of a softwood, often spruce. [6] More generally, any hard surface can act as a soundboard. An example is when someone strikes a tuning fork and holds it against a table top to amplify its sound.
