Detailed explanation of the circuit diagram of the ten-key electronic password switch
Source: InternetPublisher:抄写员 Keywords: Electronic code switch circuit Updated: 2024/07/12
Below is a simple electronic code switch. It is controlled by 10 buttons, which must be pressed in a certain order to change the output.
You can see from the buttons that when you press two buttons, you must first press them at the same time, and then press the other two buttons at the same time to enter the circuit. This type of key operation is very unusual because no one will be able to press the incrementing number buttons to open the circuit.
