Which type of fire extinguisher can put out a fire caused by electrical appliances and electrical switches?
CO2 fire extinguisher
Instead, be prepared with a Class E CO2 fire extinguisher.

Water mist extinguishers are safe and well suited for use on burning electrical equipment as the de-ionised water mist does not conduct electricity and the water mist does not form puddles which could lead to electrocution.
Which type of extinguisher is best for electrical fires?
CO2 extinguishers
CO2 extinguishers are mainly used for electrical fire risks and are usually the main fire extinguisher type provided in computer server rooms. They also put out Class B fires.
