Isolating switch‘s function

Creates a clear, visible, physical separation from the power supply, ensuring the circuit is de-energized. 

Allows electricians and engineers to work on equipment without the risk of electric shock. 

By separating the circuit, it protects against short circuits and overcurrents by preventing current flow. 

The switch's design allows for a visual confirmation that the power is disconnected, enhancing safety and certainty. 

Provides a means to quickly and safely shut down power to a section of a system in emergencies. 

Isolation switches are typically manually operated and are not designed for frequent or automatic switching of large load currents.

Isolator switches must be rated for the specific voltage and current of the system they control to prevent overheating or failure.

They should only be operated when the circuit has no load (i.e., is not carrying significant current) to prevent dangerous arcing.

In industrial settings, isolation switches often have provisions for locking in the off position as part of a formal lockout/tagout procedure to prevent accidental re-energization.
