L35 Series On Off Anti Vandal Switch

Measuring 35 millimeters in diameter and a body made of stainless steel, the L35 Series On Off Anti Vandal Switch is one of Langir’s heavy-duty anti-vandal switches.

It has a maximum switch rating of lth:5A / Ui: 250VAC, a contact resistance of ≤50 mΩ, an insulation resistance of ≥1000 mΩ, and a dielectric strength of 2000VAC.

As with the other series of anti-vandal switches from Langir, the L35 Series is best for heavy-duty use. It is non-magnetic and can resist corrosion. This makes the L35 Series great for either indoor or outdoor use.

Normally, when metals are placed outdoors, rust may occur and damage its surface but not the L35 Series. This is because the L35 Series is made from high-quality stainless steel making it corrosion-resistant. Therefore, placing it outdoor will not do any harm or in any way affect its performance.

The L35 Series is also dustproof and waterproof. This can be attributed to its ingress protection rating of IP67. Because switches like the L35 Series are commonly placed outdoors, it is inevitable that dust will make contact with them. Also, it is not always that we have a sunny weather. From time to time, raindrops can also make contact with the switch. The L35 Series has a special enclosure that prevents the penetration of objects foreign to it especially small ones like dust and liquids of any form.

The L35 Series also has an impact protection rating of IK10. When switches are placed outdoors, it is expected that people may play with it, hit it, or smash it unintentionally. In the case of a normal switch, if forces like this hit its surface, the damage is unavoidable. The L35 Series, on the other hand, will be able to withstand this. Thanks to its IK10 impact protection rating which equates to an impact made by a 5-kilogram mass from a free fall height of 400 millimeters.

These protection ratings and material composition of the L35 Series make it explosion-proof. This characteristic should not, however, be misunderstood as something that protects the L35 Series in the case of an external explosion. In some cases where electrical accidents are unavoidable, a short circuit, for example, can cause a fire. However, if you are using any of Langir’s anti-vandal switches like the L35 Series, you can avoid this scenario. This is because the L35 Series has a special enclosure that not only avoids the entry of foreign particles, as discussed above but also prevents an internal explosion from causing further damage to its neighboring surface.

With these alone, you can be assured that the L35 Series possess the quality an anti-vandal switch must have. 

Langir also understands that what we have originally designed and manufactured may not be what you actually need especially in terms of style and voltage ratings. This is why we are open to customization. Langir has a team of experts and engineers that will collaborate with you to meet all your product specifications and requirements.

If you think the L35 Series On Off Anti Vandal Switch has everything you are looking for in a 35-millimeter anti-vandal switch, then look no further than the L35 Series of Langir.
