A circuit physically functions as a sequence of successive on-off switches that form a domino structure.

hardworking circuit#1 is a realization of a schema of monotonous, repetitive circuit, using as many units as possible of relay switch to bridge up the sequential extension of cables, merely for the purpose of electricity connection 勤力電路#1 實現了一個單調、重複的電路系統，以大量繼電器連接，順序延長成極長的電線，只不過就是為了通電。
