An Isolator Switch is a manually operated device used to completely disconnect electrical equipment or circuits from the power supply for safety during maintenance or repair. Commonly used in industrial, commercial, and residential applications, isolator switches ensure safe isolation of electrical systems. Available in single-pole, double-pole, and three-phase configurations, they are often installed in distribution boards and near machinery. Isolator switches provide reliable and secure disconnection, helping prevent accidental re-energizing of circuits, making them essential for electrical safety and maintenance procedures.
