What Does NO Stand For?
NO stands for Normally Open
NO, or Normally Open, is a term commonly used in electrical and electronic systems to describe a type of switch or relay contact configuration that remains open (non-conductive) when no external force is applied. When activated, the contact closes, allowing current to flow through the circuit. This configuration is frequently employed in safety applications and automation systems, enabling devices to operate only under specific conditions.
