Mechanical eight-bit binary coded lock demonstration instrument

The utility model provides a mechanical eight-bit binary coded lock demonstration instrument. A switch of the single-pole double-throw switch is closed towards different directions to realize a logicstate '0' or '1'; the sixteen single-pole double-throw switches form eight logic units; logic expression of each logic unit is shown in the specification. In the circuit, the eight logic units are connected in series, and when the logic relationship of the whole circuit is Y = Y1 * Y2 * Y3 * Y4 * Y5 * Y6 * Y7 * Y8, the two single-pole double-throw switches of each logic unit are respectively arranged on the front surface and the back surface of the panel to be used for password decoding and password setting. During use, when an input password is the same as a set password, password decoding succeeds, a circuit is connected, and the electric control lock is started; otherwise, password decoding fails, and the electric control lock cannot be unlocked. 本专利提供一种机械式八位二进制密码锁演示仪，通过单刀双掷开关的开关向不同的方向闭合实现逻辑状态″0″或″1″，十六个单刀双掷开关构
