An isolator switch is part of an electrical circuit and is most often found in industrial applications. The switch does exactly what its name suggests in that; it electrically isolates the circuit or circuits that are connected to it.

An isolator switch is part of an electrical circuit and is most often
found in industrial applications. The switch does exactly what its
name suggests in that; it electrically isolates the circuit or circuits
that are connected to it.

Such a switch is not used normally as an instrument to turn on/off
the circuit in the way that a light switch does. Either the switch
isolates circuits that are continually powered or is a key
element, which enables an electrical engineer to safely work on
the protected circuit.

3. 
Isolator switches may be fitted with the ability for the switch to
padlock such that inadvertent operation is not possible. In some
designs, the isolator switch has the additional ability to earth the
isolated circuit thereby providing additional safety.

Such an arrangement would apply to circuits, which inter-connect
power distribution systems where both end of the circuit need to
be isolated.

4. An isolator is a switch connected after a circuit breaker. When a
circuit or a bus bar is taken out of service by tripping the circuit
breaker, the isolator is then open circuited and the isolated line is
earthed through earth switch so that the trapped line charges are
safely conducted to ground.
