Night vision devices and Swiss law: what applies, and what does not

Straight to it, because this is the question that reaches us most often: a night vision device used for observation can be bought freely in Switzerland. No weapon acquisition permit, no authorisation, no notification. The Waffengesetz mentions night vision exactly once, and it does so next to the word aiming.

A night vision aiming device, meaning a device used to aim a weapon, counts as a weapon accessory and needs an exceptional authorisation. Same image intensifier, different use, different law. The rest of this piece shows where that line runs, who draws it in an individual case, and what import and export add on top.

What the Waffengesetz actually says

The Federal Act on Weapons, Weapon Accessories and Ammunition (Waffengesetz, WG, SR 514.54) mentions night vision in one place only. Article 4 paragraph 2 letter b lists laser and night vision aiming devices as weapon accessories.

The decisive word is aiming. What is meant are devices used to aim a weapon, not devices you use to look into the night.

For weapon accessories in that sense, Article 5 paragraph 2 letter d applies: they may not be transferred, acquired or brought into Switzerland. Anyone who needs one anyway requires an exceptional authorisation under Article 28b.

What is not on that list

Observation devices. A monocular, a binocular or a panoramic device you hold to your eye or mount on your helmet is not named in Article 4 paragraph 2 letter b. That is the distinction almost every enquiry confuses, and it comes before all the others.

The form factor changes nothing about it. A single tube monocular and a dual tube binocular differ in weight, depth perception and price, not in their legal classification.

The use decides, not the housing

This is where it gets concrete. Mount an observation device on a weapon and use it to aim, and you have built exactly the device Article 4 paragraph 2 letter b names. Then the rule applies.

The hardware in your hand has not changed. Its legal classification has. Put a monocular on a weapon and aim through it, and you buy yourself a permit requirement you did not have while wearing it on a helmet.

So the most useful question before buying is not "which device?" but "how will it be carried, and what will it be used for?". That answer sets the legal position, not the product name.

Thermal: what the wording covers and what it leaves open

Article 4 paragraph 2 letter b names laser and night vision aiming devices. Thermal does not appear in the wording. Concluding from that that a thermal aiming device is therefore unrestricted would be interpretation, and interpretation is not our job. The weapons office (Waffenbüro) of your canton decides that.

For pure observation the position is the same as for night vision: thermal and COTI Thermal Fusion devices used for observing are not on the weapon accessory list. Hunting has a rule of its own, and it is drawn wider.

Hunting: a rule of its own, and it is explicit

The Hunting Ordinance (Jagdverordnung, JSV, SR 922.01) prohibits, in Article 2 paragraph 1 letter e, laser aiming devices, night vision aiming devices and device combinations with a comparable function as aids for hunting.

Three points about that matter, and all three are regularly missed:

• It is about the practice of hunting, not about ownership. The provision governs aids used while hunting.
• It covers aiming devices and combinations with a comparable function. The wording therefore also applies when the aiming function only comes into being once several parts are assembled, for example a thermal front attachment (Wärmebild-Vorsatzgerät) placed ahead of a riflescope.
• Observation devices are not named in the wording. That does not mean every use is permitted. Hunting is enforced at cantonal level, and the cantons have rules of their own.

If you hunt, settle it before you buy with the hunting authority (Jagdverwaltung) of your canton: what is allowed when tracking wounded game, what from a high seat, what for plain wildlife observation outside the hunt. The answer costs one phone call and carries more weight than any forum post.

Who decides in an individual case

Not us, and no other dealer either. Two bodies are competent:

• The weapons office (Waffenbüro) of your canton for everything under the Waffengesetz: classification as a weapon accessory, exceptional authorisation under Article 28b, import of an aiming device.
• The cantonal hunting authority (Jagdverwaltung) for anything connected with the practice of hunting.

Both will answer a factual written enquiry. Describe the device, the mounting and the intended use. Those three details are what decide the case, and a written answer is worth something if somebody asks later.

Buying and importing into Switzerland

For a delivery inside Switzerland and to Liechtenstein there is no additional step. You order an observation device, we ship it. The displayed prices include Swiss VAT, and Liechtenstein counts as domestic territory for that purpose.

And if I import one myself?

For weapon accessories under Article 4 paragraph 2 letter b, bringing the item into Switzerland is prohibited under Article 5 paragraph 2 letter d, except with an exceptional authorisation under Article 28b. An observation device does not fall under that provision.

What remains is customs and import tax, plus the export rules of the sending country. A device sitting in the EU has to be allowed to leave there first, and that authorisation is granted by the authority, not by the seller. This is the most common reason a private import stands still for weeks.

Export from Switzerland: Güterkontrollverordnung and End User Certificate

Night vision and thermal technology are dual-use goods and fall under the Goods Control Ordinance (Güterkontrollverordnung, GKV, SR 946.202.1), which SECO administers.

What matters is what that control covers: export from Switzerland, not a domestic purchase. Buy in Switzerland and stay in Switzerland, and the GKV has nothing to do with you.

A delivery to the EU or the Schengen area adds one step. After payment you receive an End User Certificate from us. You sign it and send it back, we handle the export clearance, and the device then goes out with tracking. If the licence for your country is not granted, we cancel and refund in full.

On timing we deliberately quote no figure that is not ours to quote. SECO publishes no binding processing deadline and states in its own guidance that non-critical transactions are licensed within a day and that critical destinations take considerably longer. What to plan for on your own order is stated with the night vision devices in the shop.

Accessories and clothing are not controlled goods and go out without that step. We do not deliver to Russia, Belarus or any country sanctioned by Switzerland, and that is permanent.

Incidentally, export control also explains why every data sheet carries a FOM number: Figure of Merit was introduced as a sorting measure for export decisions, not as a buying aid. Why that means less for your choice of device than the number promises is set out in our article on Figure of Merit.

Frequently asked questions

Do I need a weapon acquisition permit for a night vision device?

No. An observation device is neither a weapon nor a weapon accessory within the meaning of Article 4 paragraph 2 letter b WG. A night vision aiming device, by contrast, falls under Article 5 paragraph 2 letter d, and that needs an exceptional authorisation under Article 28b.

May I wear a night vision device on a helmet?

The Waffengesetz governs weapons and weapon accessories. An observation device on a helmet is neither of the two. Whatever else applies at the place in question, such as property rules, protected areas or cantonal regulations, is untouched by that.

Is thermal regulated differently from night vision?

For observing, neither of them is on the weapon accessory list. For hunting, the wording of the JSV is drawn wider than that of the Waffengesetz, because it expressly includes device combinations with a comparable function.

What is an End User Certificate?

A signed declaration by the recipient stating who uses the device and that it will not be passed on. It is a precondition of the export licence and not a formality we invented. We prepare it, you sign, we submit.

Does all of this apply to Liechtenstein as well?

For the purchase, yes: Liechtenstein is treated as domestic territory for VAT and needs no additional step when ordering. Under export law Liechtenstein is a case of its own, which we check per order.

Legal note

This is a summary of the statutory wording and not legal advice. What governs are the cited enactments in their version in force. Your specific case is decided by the weapons office (Waffenbüro) of your canton, and for hunting questions by the cantonal hunting authority (Jagdverwaltung). Ask them before you buy, not afterwards.

Once the legal side is settled

Then the technical side remains, and honestly that is the harder one. Tube class, form factor, phosphor, weight on the helmet: none of that is best decided at a screen. The showroom in Villmergen is open by appointment, and looking through two tubes in the dark answers more in ten minutes than any data sheet.

If you want to see what these rules mean in practice, the DTD Jerry 14 is a typical first device and the DTD PVS-14 the classic monocular; both are sold under exactly the conditions described above.
