专利汇可以提供Stepping type output switching device专利检索,专利查询,专利分析的服务。并且PURPOSE:To realize a new switching system, by using an AC induced current pulse contained in a human body for the oscillating pulse of an output switching device. CONSTITUTION:When a human body touches a touch plate A1, an AC induced current pulse is received and converted into a rectangular pulse of the plus potential through a pulse waveform converting circuit B. This rectangular pulse is applied to a BCD counter stage E via a differentiating circuit C and an output-up circuit D. A stepping output arithmetic circuit F delivers successively the stepping outputs F2-F5 in accordance with the counter value of the counter stage E. This output is fed to a display circuit G and an amplifying circuit H. Thus a user looks at a display of the output and releases his or her finger, and a stepping output is decided. As a result, a relay type station discriminating circuit I works to perform the selection of station.,下面是Stepping type output switching device专利的具体信息内容。
