Abstract

A press key switch consisting of one key matrix, one analog multiplexer structure, one signal amplifier structure, one signal trigger structure, one make/break point control structure, one debounce control, one latch structure, one signal clear structure, one CPU, one decoder, one input/output connector, one resonator, one indicator display, and one current control structure, has the features of: (1) The key matrix has includes one layer membrance on which there are installed holes with expected count, in which each hole can let one nonmagnetic core pass, and the core is bound on the key cap to in/out hole depending key cap press/release, and on top/bottom surface of the membrance independently printing metal sheet around the hole to constitute node of cross-induction; (2) In which, when pressing, core will have current flow due to scan and generate micro magnetic force, again due to effort generated by pressing key, making core along hole pass membrance, resulting in return line below to generate micro current signal, then after analog multiplexer structure selects return source, then via amplifier to amplify signal, and by signal debounce control clearing unstable noise or grade area, then through electronic circuit, reading ON point set value back, adjusting ON/OFF enable level, finally from signal locking device reading signal back and clearing it.
