The table below summarises the plug types, voltage and frequency of electrical current in both Azerbaijan and Switzerland.
|Plug Types||C||C, J|
|Frequency of electrical current||50Hz||50Hz|
Azerbaijan uses Plug Type C.
In Switzerland there's more than one socket type in use.
You will need this adaptor:
Socket Type C
(Azerbaijan) to Plug Type J
Switzerland also uses Socket Type C, which is used in Azerbaijan. If using an appliance that has a Type C Plug in the Type C Sockets of Switzerland, you will not need an adaptor.
The voltages found in Azerbaijan (220V) and Switzerland (230V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Azerbaijan and Switzerland is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
