Touch switch
专利汇可以提供Touch switch专利检索，专利查询，专利分析的服务。并且PURPOSE:To obtain a touch switch which is immunized against noise, by constituting the switch to exclude the noise, when noise of less than the prescribed number of times exist in a prescribed time. CONSTITUTION:When a person touches a touch plate 10, an input voltage VA is inputted into the 1st operational amplifier 16 and compared with a prescribed voltage VB. A rectangular alternating output is obtained as the output VC of the 1st operational amplifier 16 and a condenser 18 is charged and discharged. When the terminal voltage VD of the condenser 18 becomes lower than the set voltage VE of the 2nd operational amplifier 22, the output VO becomes negative and releases the cleared condition of a shift register 23. When the shift register 23 is under cleared condition, the output VC of the 1st operational amplifier 16 is inputted into a clock terminal and data DATA are shifted by the rectangular alternating output, and then, an output is obtained at the output terminal VO, into which shift pulses are inputted for prescribed times.，下面是Touch switch专利的具体信息内容。
