Switchmode is a type of power supply converting the 240V to the necessary voltage.

Switchmode runs higher efficiency and lower weight as the transformers are hell a lot smaller.

Instead of transforming 50Hertz it transforms the voltage at many kilohertz just above audio frequencies. (Too technical sorry)

Noticable when a transformer starts to fails get a high pitch screamer.
