What is a DC common wire?
“Common” is a point of reference shared throughout a circuit, typically the node in reference to which every other node is described. In the case of a single-pole double-throw (SPDT) switch, common (also called the pole) is the terminal which the “normally open” and “normally closed” terminals switch to.
