An 8-bit DIP switch, from left to right 1~8, the maximum value can be up to 128. When the code is not dialed, the status of the switch is all up, that is, on the ON/DP side, when the DIP switch is close to the number On one side, it is the dial-down state. Next, the correspondence between the number on the switch and the actual decimal number will be described in detail.

1. If you want to dial the number 1, you can directly dial 1 on the switch, because it can be seen from the figure that 1 corresponds to the zeroth power of 2, and the zero power of 2 is equal to the decimal one.

2. If you want to dial 10, you can dial 2 and 4 on the switch. As you can see from the figure, 2 corresponds to the 2nd square, which is equal to 2 in decimal; 4 corresponds to the cube of 2, which is equal to decimal. 8; 2+8=10
