Add convenient ON/OFF control to a compatible electrical cable with the TFF Waterproof Inline Power Switch.

The switch is housed inside a durable black enclosure with a visible orange sealing gasket, four securing screws and cable glands at both ends. The glands help secure the incoming and outgoing cables while supporting a neat, enclosed installation.

A red rocker switch provides clear ON and OFF positions, while the integrated mounting tabs allow the enclosure to be secured to a suitable surface. It is suitable for compatible home appliances, outdoor equipment, RV installations, marine applications, pumps and lighting systems when professionally installed and used within the correct electrical ratings.

Compatibility depends on the appliance voltage, current draw, cable size, wiring configuration and installation environment.

Always confirm the electrical requirements of the appliance before installation.

How to Use

1. Disconnect the circuit completely from the power supply.
2. Confirm that the switch is suitable for the intended voltage, current and cable size.
3. Remove the four enclosure screws and carefully open the cover.
4. Loosen the cable glands on both ends.
5. Route the incoming power cable through one gland.
6. Route the outgoing appliance cable through the opposite gland.
7. Connect the wires to the correct internal switch terminals according to the required wiring configuration.
8. Check that no bare conductor is exposed outside the terminals.
9. Position the sealing gasket correctly around the enclosure.
10. Close the cover and tighten the four screws evenly.
11. Tighten both cable glands firmly around the cables.
12. Secure the enclosure using the mounting tabs where required.
13. Restore power only after checking the complete installation.
14. Press "I" to switch the connected appliance ON and "O" to switch it OFF.

Safety and Important Usage Information

• Electrical installation should be completed by a qualified electrician or suitably experienced person.
• Disconnect the power supply before opening, wiring or servicing the switch.
• Never work on live electrical wiring.
• Confirm the circuit voltage and current requirements before installation.
• The maximum current or wattage rating has not been provided. Do not connect a load until compatibility has been confirmed.
• The supplied reference information indicates that the rocker illumination may require DC 12V only.
• Do not connect a DC 12V indicator-light circuit directly to 110V or 220V.
• The switch contacts and rocker illumination may use different electrical connections or ratings.
• Follow the correct wiring diagram for the specific switch configuration supplied.
• Do not rely on wire colour alone. Confirm every conductor before connection.
• Use cables that fit securely inside the cable glands.
• Ensure the sealing gasket is clean, correctly positioned and undamaged.
• Tighten the cable glands to help prevent cable movement and moisture entry.
• Do not submerge the switch in water.
• Do not install it where it will remain underwater or be exposed to continuous high-pressure water.
• Do not use the switch if the enclosure, gasket, terminals, rocker or cable glands are damaged.
• Keep the enclosure closed during normal use.
• Keep out of reach of children.

Care and Maintenance

• Disconnect the power before inspecting or cleaning the switch.
• Wipe the exterior with a soft, slightly damp cloth.
• Do not use abrasive cleaners, solvents or metal brushes.
• Check the enclosure screws periodically and tighten them evenly where necessary.
• Inspect both cable glands for looseness or damage.
• Check that the cables remain firmly secured.
• Keep the sealing gasket clean and correctly seated.
• Replace the switch if the housing becomes cracked or allows moisture to enter.
• Do not modify the enclosure or enlarge the cable openings.
• Store the unused switch in a clean and dry location.

Please Note

• The package includes one inline power switch only.
• Electrical cables, appliances, lights, pumps, RVs, boats, rain barrels and installation tools shown in demonstration images are not included.
• No IP protection rating has been provided.
• No maximum amperage or wattage rating has been provided.
• Confirm the switch rating against the connected appliance before use.
• The red rocker may illuminate only when wired to a compatible DC 12V lighting circuit.
• Do not assume that the rocker light is suitable for direct connection to 110V or 220V.
• The enclosure is designed to support moisture-resistant installation when correctly assembled, but it must not be submerged.
• Product dimensions may vary slightly due to manufacturing tolerances.
