Professional 4-Pin Waterproof Rocker Switch 16A 250VAC Illuminated Power Control
This 4-Pin Waterproof Rocker Switch is a high-reliability electrical component designed for robust Double Pole Single Throw (DPST) power management. Featuring a translucent red actuator with integrated status illumination and a protective silicone boot, this switch is engineered for maximum durability in environments exposed to moisture, dust, and heavy use.
Key Product Features
-
Integrated Waterproof Silicone Boot: Features a factory-installed, flexible transparent cover that seals the rocker actuator against water ingress and debris while maintaining full tactile operation.
-
High-Visibility Illuminated Actuator: The vibrant red translucent rocker contains an internal lamp that glows when the switch is in the "ON" position, providing an essential safety indicator in low-light conditions.
-
Double Pole Single Throw (DPST): Equipped with four terminals to simultaneously control both the live and neutral lines, ensuring complete electrical isolation and increased safety when the device is turned off.
-
Industrial Power Rating: Robustly rated to handle 16A @ 250VAC and 20A @ 125VAC, making it ideal for high-wattage machinery and power tools.
-

Top 3 Customer Questions & Concerns þ
þ How do I wire this switch so the light only turns on when the machine is running? To ensure the light functions as a status indicator, you connect your incoming power to the "Line" side (usually the center or marked pins) and your device to the "Load" side. Since the internal lamp is connected across the output terminals, it will automatically illuminate only when the circuit is closed and the switch is in the "ON" position.
Will the waterproof boot yellow or crack over time? The boot is made from high-grade silicone designed for UV resistance and long-term flexibility. Unlike standard plastics, silicone remains pliable in extreme temperatures and is resistant to many common oils and chemicals, ensuring the switch remains protected even in harsh industrial settings.
þ Can I use this for a 3-wire grounded system? Yes. While this switch breaks the Live and Neutral wires (the 4 pins), your ground wire should always bypass the switch and remain connected directly from the power source to the metal frame of your equipment for continuous safety grounding.
