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 ...
Cherry ML switch and keycap. Cherry Mechanical Low-profile (ML) switches are available in a tactile variant, with force and operating characteristics similar to that of Cherry MX Brown switches, but with shortened travel. The rated service life of ML switches is 20 million keystrokes, approximately 1 ⁄ 5 that of the rated MX life. [24]
The Razer Switchblade had a traditional netbook form factor. When compared to a standard Nintendo DS the Switchblade's dimensions are only slightly larger. When the lid is folded, the Switchblade is 172 mm × 115 mm × 25 mm. [1] The Razer Switchblade was about 7 mm thicker than the MacBook Air when folded.
The Model F was a series of computer keyboards produced mainly from 1981–1985 and in reduced volume until 1994 by IBM and later Lexmark. [1] Its mechanical-key design consisted of a buckling spring over a capacitive PCB, similar to the later Model M keyboard that used a membrane in place of the PCB.

In electronics, a continuity test is the checking of an electric circuit to see if current flows (that it is in fact a complete circuit). A continuity test is performed by placing a small voltage (wired in series with an LED or noise-producing component such as a piezoelectric speaker ) across the chosen path.
A common form of in-circuit testing uses a bed-of-nails tester.This is a fixture that uses an array of spring-loaded pins known as "pogo pins". When a printed circuit board is aligned with and pressed down onto the bed-of-nails tester, the pins make electrical contact with locations on the circuit board, allowing them to be used as test points for in-circuit testing.
