When you sell on Alibaba.com, one of the most critical product attributes for electrical switches is the **IP **(Ingress Protection). This two-digit code, defined by the international IEC 60529 standard, tells buyers exactly how well your switch protects against solid objects (first digit) and liquids (second digit) [4].
The first digit ranges from 0 to 6, measuring protection against solids like dust, fingers, and tools. The second digit ranges from 0 to 9, measuring protection against water in various forms—from dripping to high-pressure jets to temporary submersion. Understanding these numbers is essential for Southeast Asian exporters targeting global B2B buyers who need reliable environmental protection for their applications.
IP Rating First Digit: Solid Object Protection (0-6)
| IP Code | Protection Level | Test Object | Typical Application |
|---|---|---|---|
| IP0X | No protection | None | Not recommended for any commercial use |
| IP1X | Large solids | 50mm sphere (hand) | Indoor dry locations only |
| IP2X | Fingers | 12.5mm sphere | Indoor residential switches (IP20) |
| IP3X | Tools/wires | 2.5mm sphere | Light industrial indoor |
| IP4X | Small wires | 1.0mm sphere | Control panels, indoor machinery |
| IP5X | Limited dust | Dust chamber test | Semi-outdoor, protected areas |
| IP6X | Dust-tight | 8-hour dust exposure | Outdoor, harsh environments (IP65/IP67) |
IP Rating Second Digit: Water Protection (0-9)
| IP Code | Water Protection | Test Condition | Duration |
|---|---|---|---|
| IPX0 | No protection | None | N/A |
| IPX1 | Dripping water | Vertical drops | 10 minutes |
| IPX2 | Dripping water (tilted) | 15° angle drops | 10 minutes |
| IPX3 | Spraying water | 60° spray cone | 5 minutes |
| IPX4 | Splashing water | All directions | 5 minutes |
| IPX5 | Water jets | 12.5L/min nozzle | 3 minutes (IP65) |
| IPX6 | Powerful water jets | 100L/min nozzle | 3 minutes |
| IPX7 | Temporary immersion | 1 meter depth | 30 minutes (IP67) |
| IPX8 | Continuous immersion | Specified depth/pressure | Per manufacturer spec |
