GUS Grounded Adaptor Plug –
Switzerland
Modifies the following grounded appliance plugs to fit electrical outlets in Switzerland: Australia/New Zealand/China, Continental Europe (Schuko)*, India/Middle East (5 Amp), Israel, Italy, North America and United Kingdom/Hong Kong.
Do I need a grounded adapter? If your North American appliance plug has two flat blades and one round pin, your appliance is grounded.
IMPORTANT: Adapter plugs DO NOT convert electricity; they simply modify foreign outlets. If your grounded appliance is multi-voltage (120/240 or 100-240 volts) you only need a grounded adapter plug. If the appliance is 120 volts only you need a grounded transformer to convert the voltage and a grounded adapter plug to modify the outlet.
