Key Features
1. IP68 Waterproof – Fully Submersible
Unlike standard IP67 switches (temporary immersion), this switch is rated IP68, meaning it can withstand continuous immersion in water beyond 1 meter. The sealed cable design eliminates the weak point where moisture typically enters through wiring terminals.
2. 20A High Current Capacity
With a rated heating current (Ith) of 20A at 250VAC, this switch is capable of handling heavy loads such as:
Boat bilge pumps
RV lighting circuits
Marine navigation lights
DC motors and solenoids
Industrial control panels
3. Built-in 12V Blue LED
The integrated 12V blue LED provides clear visual status indication. The LED is non-polarized, simplifying installation – no need to worry about positive/negative orientation.
4. Sealed Cable – Ready to Install
The factory-attached sealed cable eliminates the need for customers to solder or crimp terminals. This reduces installation time and improves long-term reliability, especially in humid or wet environments.
5. Multiple Switching Functions
| Function | Description |
|---|---|
| Self-locking (Maintained) | Stays in position when pressed |
| Self-resetting (Momentary) | Returns to original position when released |
Both options available per customer requirement.
6. Wide Operating Temperature Range
Rated for -30°C to +85°C, this switch performs reliably in freezing winters and hot engine compartments.

Comparison: IP68 vs IP67 – Why It Matters for Marine Applications
| Feature | IP67 | IP68 (This Switch) |
|---|---|---|
| Water immersion | Temporary (30 min at 1m) | Continuous (>1m, >30 min) |
| Suitable for boat decks | Limited | ✅ Fully suitable |
| Sealed cable option | Rare | ✅ Standard |
| Long-term reliability in wet environments | Moderate | Excellent |
For marine and RV applications exposed to rain, splashing, or occasional submersion, IP68 is the safer choice.
Installation Notes
