Switch is used to make or break an electrical circuit, isolator is used for isolating a circuit for maintenance, and circuit breaker is used for protecting the circuit from overloads and short circuits.

Switch is used to manually open or close an electrical circuit.
Isolator is used to isolate a circuit for maintenance purposes, ensuring no current flows through it.
Circuit breaker is a safety device that automatically interrupts the flow of current in a circuit in case of overloads or short circuits.
