Disconnect switches are predominantly employed in electrical applications to provide safety during maintenance. They serve a critical function by isolating sections of an electrical system, ensuring that maintenance personnel can work on equipment without risk of accidental energization. This isolation protects workers and enhances safety, especially during repair or inspection activities.

In addition to ensuring safety, disconnects allow for a clear demarcation of electrical circuits, which simplifies maintenance procedures. Proper usage of disconnects helps prevent electrical accidents and ensures compliance with safety regulations. Therefore, their primary role is focused on safety, making them invaluable in the context of maintenance work on electric systems.
