MUSIKQQ Arcing damages the electrical contacts, and a sustained arc may prevent the open contacts from removing power from the system being controlled. When relay contacts open to interrupt a high current with an inductive load, a voltage spike will result, striking an arc across the contacts. In AC systems, where the current passes through zero twice for each cycle, all but the most energetic arcs are extinguished at the zero crossing. The less common configuration, when the NO and NC contacts are simultaneously closed during the transition, is make-before-break or M-B-B.|How We Improved Our Slot Machine Simulator {In one|In a single} Week(Month, Day)
