Source: InternetPublisher:柯南道尔 Keywords: Electronic combination lock MDASH Updated: 2021/01/28
Circuit working principle: lC1 is a combination lock special integrated circuit 5C058. Its
pins 1-6 are externally connected to the key switch to the positive pole of the power supply. These are six valid key input terminals. Unlocking
must follow the sequence A-F. Pin 7 is the negative pole of the power supply. Pin 8 is the dummy key input
terminal and is externally connected to the invalid key switch. You can randomly insert one or several of them into the keyboard to make them look like
real ones.
