The United States keyboard
Von mademms, 03.05.2012, 05:18The song is represented by IBM squatting type spring membrane keyboard, this time in286very active keyboard full name is buckling spring bend axis of the spring film type mechanical keyboard ( buckling, spring means the curved spring ) it and the mechanical switch keyboard, there's a big difference between.PC remote control Some say by typing it like in the piano music feeling, it is sturdy and durable, not easy to be damaged, let them even normal life has been to, but still be in circulation on the market.
Each layer of the double-layer structure is the key cap is spring,If I am rightspinach008 the 5 layer of the film sheet in the metal disk is composed of a switch circuit, an upper black piece is made of rubber used to protect film, in black rubber piece, is a layer of carbon membrane, the contact is a good print. There is another layer of the printed circuit and the contact, but if two piece placed directly, each of the contacts will be in long-term communication.
When you press the key for nearly 3/ 4 of travel time, spring reaches the limit of compression and bending moment and hitsblackcurrant the wall makes a click sound ( this and other mechanical switch keyboard switch contact sound completely different, really admire IBM guys creative ah ) at the same time as the angle changes make the following module through principle of lever pressing, exposure to the thin film switch circuit. To make this ingenious design is the key for realizing the internal structure of the angle ( no wonder people evaluate the small spring pool countless designers wisdom ).aprico
This keyboard is due to the high cost,date in order to control the PC overall cost, has now been discontinued, but due to its inability to replace the hand,bluetooth keyboard and excellent quality, so the market is still very much alive.
