Abstract
An encryption keyboard is provided, especially an encryption keyboard including a front spying and detecting protection system. The encryption keyboard comprises a panel and a main control panel. A sealed flexible printed circuit board (PCB) is set between the panel and the main control panel. A circuit for preventing from spying and detecting is set in the sealed flexible circuit. The circuit for preventing from spying and detecting is connected to the surface of the sealed flexible circuit through a circuit pin, and is connected electrically to the control circuit of the main control panel for realizing a self-destroyed function through the circuit pin. The keyboard also includes a split style key grain, which comprises a keycap and a press post. The keycap comprises a cap top and an admission space which is positioned on the undersurface of the cap top and includes a downward opening. The keycap sockets the press post through the admission space, and a gap matching is formed between the press post and the wall of the admission space.
