Switzerland Power Plugs, Wall Sockets & Electrical Outlets
In Switzerland, power plugs and sockets (electrical outlets) of Type C (CEE 7/16 (Europlug), two round pins, ungrounded) and Type J (SEV 1011, two round pins plus offset grounding pin, grounded) are used. Wall sockets run at 230V and 50Hz. Check if you need a travel adapter, electrical adapter or voltage converter before travelling to Switzerland.

Switzerland Travel Adapter Guide
If you're traveling to Switzerland, understanding the local Switzerland power plug standard will help you pack the right gear before you leave. Switzerland relies on two plug types for its AC power plugs and sockets: the grounded Type J for household appliances and the compact, ungrounded Type C Europlug for smaller electronics. Visitors from outside Europe will almost always need an adapter, since Swiss sockets differ from those used in North America, the UK, and most of Asia.
Voltage and Frequency in Switzerland
Switzerland operates on a 230V supply at 50Hz, in line with the rest of continental Europe. This standard applies nationwide, so once you have the correct plug adapter, any device rated for 220-240V will run normally on Swiss power without additional equipment.
Dual-Voltage Devices and Switzerland
Many modern electronics, including phone chargers, laptop power supplies, and camera battery chargers, are dual-voltage and designed to accept anywhere from 100V to 240V. For these devices, travelers only need a plug adapter to physically fit Swiss Type J or Type C outlets, not a voltage converter. Always check the voltage rating printed on the device or charger before plugging in, since single-voltage appliances built for 110-120V markets will require a separate converter.
Understanding Switzerland's Power Plugs and Sockets
Switzerland's national standard, Type J (SEV 1011), is a distinctive 3-pin plug featuring two round 4mm pins and an offset grounding pin set between and below them. This grounding pin design, along with a hexagonal recessed socket shape, prevents incompatible plugs from other countries from being inserted, while still allowing ungrounded Type C Europlugs to fit for low-power devices. Type J delivers reliable 10-amp grounded power for household appliances, precision instruments, and medical equipment running on Switzerland's 230V, 50Hz system.
The Type C Europlug, by contrast, is a two-pin ungrounded plug rated for just 2.5A, making it suitable only for double-insulated Class II devices such as phone and tablet chargers, cameras, and laptops that don't require a ground connection. It fits into Type J sockets but without a grounded connection, so higher-power appliances like hair dryers, kettles, or heaters should never rely on a Type C plug.
- Type J: grounded, 10A, two round pins plus an offset grounding pin, used exclusively in Switzerland and Liechtenstein
- Type C: ungrounded, 2.5A, two round pins, compatible with Type J sockets but only for low-power electronics
- Both plug types operate on Switzerland's standard 230V, 50Hz electrical supply
Frequently Asked Questions
Yes, unless your home country already uses Type J or Type C plugs. Switzerland's Type J socket has a unique hexagonal shape and offset grounding pin found nowhere else, so travelers from most countries will need an adapter to plug in their devices.
Most phone chargers are dual-voltage and accept 220-240V, which matches Switzerland's 230V supply, so a voltage converter isn't needed. You'll just need a plug adapter, such as one accepting a Type C Europlug, to physically fit the Swiss Type J outlet.
Switzerland uses 230V at 50Hz, consistent with the broader European electrical standard. This applies throughout the country, so any dual-voltage or 220-240V-rated device will function normally once connected with the correct plug adapter.
Pack a plug adapter compatible with Switzerland's Type J sockets, since Swiss plugs will not fit into outlets from other countries and vice versa. If you're bringing a Europlug-style Type C device, it will fit directly into a Type J socket, though only for low-power, ungrounded electronics.
