Switzerland uses a different plug shape (Type C/J) and runs on 230V — you'll need a plug adapter, and possibly a voltage converter for single-voltage devices.

Type C (two round pins, ungrounded ("Europlug")), Type J (three round pins (Swiss style)).
Switzerland uses Type C (two round pins, ungrounded ("Europlug")), Type J (three round pins (Swiss style)).
Yes — Switzerland's outlets use a different shape than US plugs, so you'll need a plug adapter.
Switzerland runs on 230V at 50Hz, notably different from the US standard of 120V — check that your device is rated for this voltage before plugging in directly.
Most modern electronics (phone and laptop chargers) are dual-voltage (100-240V) and only need a plug adapter, not a converter. Single-voltage, high-wattage devices like hair dryers or straighteners may need an actual voltage converter — check the label near the plug prongs for the input voltage range.
