An isolation switch is fundamental when working with electrical circuits, as they are used to ensure the circuit is safe and de-energized which allows maintenance work to take place. Also referred to as main switches, these devices separate the circuit from the main power source and dispels any trapped charges. A range of ratings and phase options are available from top trade brands, all offering useful features and benefits.
