Switzerland: infrastructure
Switzerland relies mainly on hydroelectric power, nuclear power and natural gas, and plans to phase out its five nuclear power plants as they reach the end of their lives, with 2044 given as a phase-out date.

Intrinsically Safe Smartphone Supplier in Switzerland
The IS-04Z1 is an intrinsically safe Android handset designed for solvent and powder atmospheres, from a production building in Basel or Visp to a loading rack at Cressier and a digester hall at a cantonal wastewater works. This page sets out how an intrinsically safe smartphone supply route to Switzerland will work for the IS-04Z1, and what is and is not available before launch.

Short answer. An intrinsically safe smartphone for Switzerland cannot be bought yet: the SAMS IS-04Z1 is pre-launch (certification in progress, no certificate issued), and the datasheet, certification schedule and safe-area evaluation units are available now.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

More about Switzerland that matters for portable equipment
Switzerland: industry on the ground
Basel is Switzerland's main pharmaceutical centre, home to both Novartis and Roche.
Switzerland: infrastructure
Petroleum and motor fuels account for 43% of energy consumed, electricity 26% and gas 15%, with households and transport each using about one third and manufacturing and services each just under one fifth.
Switzerland: industry on the ground
Machinery, chemicals, vehicles and metals are leading industries, so classified areas occur more in chemical and pharmaceutical plants and process industry than in oil and gas.
The term · intrinsically safe
What “intrinsically safe” means for a smartphone
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In Switzerland. Intrinsic safety suits short, frequent rounds through multi-room pharmaceutical buildings and the depots at Vernier, where a handheld must be wiped between rooms and carried across airlocks. One device rated for both gas and dust removes the swap at the airlock, and a full shift on one charge avoids interruptions.
The route · supply
Sourcing the IS-04Z1 for Switzerland
Supply of the IS-04Z1 to Switzerland starts only after certification, through authorised distributors. Until then a buyer can request the datasheet and the written certification schedule, and arrange a safe-area evaluation unit, which puts the site on the list for the right local channel at launch.
- 01
Request the datasheet
The technical specification, marking target and conditions of use, sent by email.
- 02
Ask for the certification schedule
Which certificates are in progress, in what order, and what is still to be confirmed.
- 03
Evaluate in a safe area
Evaluation units can be used for connectivity, MDM enrolment and workflow testing outside classified areas.
- 04
Register for launch
Tell us the site, zone, gas group and quantity so the right authorised distributor can contact you.
Questions · Switzerland
Frequently asked questions
Can we buy an intrinsically safe smartphone in Switzerland today?
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
What does an intrinsically safe smartphone in Switzerland cost?
SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined quantity and site.
What does ‘intrinsically safe’ mean for the IS-04Z1?
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is in progress.
Which sites in Switzerland does this cover?
The market guide for Switzerland covers Basel and Schweizerhalle, Visp, Monthey, Kaisten and the Fricktal, among others. Site-level pages are linked below.
How will SAMS supply Switzerland?
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
Which Swiss industries need intrinsically safe phones?
Chemical and pharmaceutical plants, fuel depots, gas networks, wastewater and biogas plants, and some manufacturing lines. The economy leans on machinery, chemicals, vehicles and metals more than oil and gas. Ask each site for its explosion protection document to see where zones exist.
How does mountain weather affect Ex handheld devices in Switzerland?
Alpine sites can be very cold, with snow and large temperature swings, which reduces battery capacity and affects touchscreen use with gloves. Check the lowest rated ambient temperature on the certificate and the water ingress rating, and carry spare batteries in warm storage.
Which languages does the handset support for Swiss users?
Android 16 carries German and the other working languages used in Switzerland, according to the sheet. Confirm the specific language packs and keyboard layouts you need during an evaluation, particularly for crews who work across language regions.
