When your equipment operates in wet, outdoor, or even underwater environments, waterproof performance isn’t just a feature — it’s a safeguard for long-term reliability.
Many buyers ask the same question: Both are high waterproof ratings, so what exactly separates IP67 from IP68? And which one should I choose?
Let’s break it down clearly in terms of structure, sealing performance, and real-world applications.
1. IP67: Reliable Protection for Outdoor & General Wet Conditions
IP67 is one of the most commonly used high-level waterproof ratings. It’s designed for outdoor environments and occasional static water immersion.
An IP67 push button switch can effectively block rain, moisture, and dust. It can also withstand temporary submersion in still water without affecting functionality. This makes it ideal for:
-
Outdoor equipment
-
Control panels
-
Measurement instruments
-
Non-continuous immersion applications
Structurally, IP67 provides solid sealing performance through standard gasket and sealing ring designs. However, it is not engineered for prolonged deep-water exposure or high-pressure water environments.
For most outdoor and industrial surface installations, IP67 is more than sufficient.
2. IP68: Maximum Sealing for Extreme Environments
IP68 represents the highest level of waterproof protection in practical industrial applications. Its sealing capability significantly exceeds that of IP67.
To achieve this, IP68 switches typically use advanced internal sealing processes, such as resin potting or full encapsulation, which completely seal internal components and eliminate potential water entry paths.
In addition:
-
The sealing ring is tightly compressed into the metal housing
-
Structural pressure is applied to form a fully enclosed chamber
-
The design prevents water ingress even under long-term immersion
-
It withstands higher water pressure and heavy water flow
IP68 is specifically designed for harsh, high-humidity, or long-term underwater environments.
3. The Core Difference in Simple Terms
-
IP67 → Suitable for outdoor use and temporary static immersion
-
IP68 → Designed for prolonged submersion and extreme waterproof demands
If your equipment operates in standard outdoor conditions, IP67 is typically adequate and cost-effective.
However, if the working environment is consistently wet, underwater, or exposed to strong water pressure — and reliability is critical — IP68 provides a higher level of security and durability.
How to Choose?
-
Think about the real operating conditions, not just the label.
If there’s any possibility of long-term immersion or severe environmental exposure, investing in IP68 can prevent costly failures later. Waterproof performance is not only about meeting standards — it’s about ensuring stability over time.
Choosing the right rating from the start protects both your equipment and your reputation.
· Space limits: Traditional industrial switches often need big installations, which restricts design freedom.
· Environmental toughness: In harsh environments, standard switches break down early because of water or dust getting in.
This new solution gets rid of these issues. It provides a flexible part that balances looks, durability, and performance. So, it becomes a top pick for industries from aerospace and defense to consumer electronics and renewable energy.
