IP67 vs IP68 Push Button Switches: ONPOW Explains the Difference
When selecting a push button switch for industrial equipment, outdoor devices, marine systems, or harsh environments, one of the most important specifications to consider is the IP protection rating. Two of the most common waterproof ratings are IP67 and IP68.
As a professional push button switch manufacturer, ONPOW is here to explain the differences and help you choose the right switch for your application.
What Does IP Rating Mean?
IP (Ingress Protection) is an international standard that indicates how well a device is protected against solids and liquids.
The first digit 6 means complete protection against dust.
The second digit indicates the level of water protection.
| Rating | Dust Protection | Water Protection |
|---|---|---|
| IP67 | Dust-tight | Protected against temporary immersion up to 1 meter for 30 minutes |
| IP68 | Dust-tight | Protected against continuous immersion under specified conditions |
IP67 Push Button Switches
IP67-rated push button switches are designed to withstand temporary water exposure.
Typical Applications
Industrial control panels
Food processing equipment
Outdoor machinery
EV charging stations
Automation equipment
Advantages
✅ Excellent protection against rain and splashing water
✅ Suitable for occasional water immersion
✅ Cost-effective solution for most industrial applications
✅ Reliable performance in dusty environments
IP68 Push Button Switches
IP68-rated push button switches provide a higher level of waterproof protection and can operate while continuously submerged in water under specified conditions.
Typical Applications
Marine equipment
Underwater devices
Mining machinery
Special vehicles
Harsh outdoor environments
Advantages
✅ Superior waterproof performance
✅ Suitable for long-term exposure to water
✅ Enhanced durability in extreme environments
✅ Ideal for critical applications requiring maximum protection
IP67 vs IP68: Which One Should You Choose?
| Feature | IP67 | IP68 |
|---|---|---|
| Dust Protection | Excellent | Excellent |
| Rain Resistance | Yes | Yes |
| Splash Resistance | Yes | Yes |
| Temporary Immersion | Yes | Yes |
| Continuous Immersion | No | Yes |
| Cost | Lower | Higher |
| Typical Applications | Industrial Equipment | Marine & Extreme Environments |
