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.

Intrinsically Safe Smartphone Distributor 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. Hydraulic power was used instead of steam in Swiss industry because of the mountainous terrain and lack of coal, which explains the concentration of hydro stations and tunnels in the Alps. An intrinsically safe smartphone distributor in Switzerland would carry the IS-04Z1 to these buyers once certification completes.

WhereSwitzerland
Short answer. Switzerland has no appointed SAMS distributor yet: the IS-04Z1 is pre-launch (certification in progress, no certificate issued, launch planned for Q4 2026), and distributor applications are open.
Status: pre-launch. IECEx, ATEX, UKEX and NEC 500 certification is in progress and no certificate has been issued; launch is planned for Q4 2026. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

Field notes · Switzerland
More about Switzerland that matters for portable equipment
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.
Switzerland: projects and investment
The Mantelerlass, passed on 29 September 2023, sets a target of 35 TWh a year from new renewable technologies by 2035, compared with about 6 TWh a year in 2022, which implies major construction work.
Switzerland: industry on the ground
Switzerland produces no fossil fuels and imports petroleum, so refining and bulk fuel handling is limited, while storage depots and distribution terminals are the main flammable-liquid sites.
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 · distribution
Distributing the IS-04Z1 in Switzerland
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for Switzerland. Each application is reviewed on its merits. Because opening a certified Ex handset in an ordinary workshop invalidates its certificate, the partner must be able to support and service the device locally.
What SAMS looks for in a partner
- Operator relationships
- Existing supplier registrations or a clear route to them with the main operators and contractors in Switzerland.
- Ex-competent staff
- People who understand zone classification, markings and the conditions of a certificate.
And equally important
- Local-language support
- Documentation, training and helpdesk in the languages the workforce uses.
- Service capability
- Spares, battery replacement and repair routed through SAMS-approved channels.
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?
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
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 do I become a SAMS distributor for Switzerland?
Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for Switzerland.
Does Switzerland accept ATEX certified devices?
Switzerland is not an EU member, but it generally aligns its equipment rules with European requirements, so ATEX-marked devices are commonly accepted. Confirm the current requirement and any Swiss conformity marking with the site operator or your importer before ordering.
What language should device documents be in for Swiss sites?
German, French and Italian are all national languages depending on the canton, and many industrial sites also work in English. Ask the operator which language it requires for instructions and certificates, and provide the declaration of conformity together with the Ex marking details.
Can the IS-04Z1 be wiped down in a Swiss pharmaceutical building?
IP68 sealing and a rugged build are aimed at a cleaned plant rather than a rained-on one, but your cleaning agents and routine must be checked. Test a unit with your own procedure and confirm compatibility with the site's validation team.
