What is the role of an electrical interlock switch on panel doors?

The role of an electrical interlock switch on panel doors is integral to ensuring personal safety during maintenance and servicing tasks. When a panel door is opened, the interlock switch interrupts the local power supply, effectively disabling the electrical components within the panel. This action prevents accidental energization and safeguards individuals from potential electric shock or injury as they work on the equipment.

In various systems, maintaining a safe working environment is paramount, and the interlock switch serves to automate this safety feature. It ensures that the equipment cannot be operated while access to the panel is granted, thus significantly reducing the risk of accidents.
