Dimmer Switch, DC12V-24V Double Dimmer Light Switch, 120W 5A PWM RV LED Dimmer Switch 2Gang Rotary RV Light Switch for 12V LED Lights in Motorhome/RVs/Campervan/Boat/Truck-Silver

I went cheap the first time, and bought switches on eBay that were 1/4 the price.They had really bad electrical feedback through the switch. And one side of the dimmers didn’t even do anything. It was on or off.So I bought these switches, and they work awesome!! And they look super nice too! And you can tell the second you fondle your dirty hands on them, that they are very good quality.I am very happy to have found themBy the way, I will describe my set up a bit so people can compare scenarios with mine.I built an ice shack out of an enclosed trailer. Put a dropped ceiling in it and installed 8 6” RV LED recessed/puck lights. I wanted to be able to control 4 different zones with different light intensity. So I put in 2 double dimmer switches.I run a WFCO power supply/converter like you’d see in an RV. And I ran all my wiring for all my charging ports, lights, fish finder power hook ups, 120v recessed power strip for TV and appliances, etc.I run 2 AGM batteries in parallel hooked to the converter. They charge automatically when generator power is supplied.The problem I was having was with the diesel heaters. Everytime the pumps would cycle their magnetic fuel pumps, the lights would flicker, dim, and change brightness. And this would happen whether I had the generator hooked up or not. Because while the generator is on, the converter automatically switches the battery power off, and starts charging the batteries, and it converts the generator signal into its own 12v power source.I could have tried to use a ground isolator for the diesel heaters, but all the RV pages pointed me towards the switches just being junk if you buy cheap ones. They will do that no matter what you do.And also I used 12 gauge wiring for all my 12 volt fixtures. So I dont have any power delivery issues either.Anyways. I digress. This could have just been the biggest waste of my time writing this up, but hopefully I get a thumbs up someday to make it all worthwhile……

Pros:• Independent Control for Two Circuits: The dual rotary dimmer allows independent adjustment of two lighting circuits, offering precise brightness control for different areas or tasks.• Smooth and Flicker-Free Dimming: Provides a 3%-100% dimming range with smooth and flicker-free operation, maintaining consistent light quality.• Energy Efficient: Helps reduce power consumption by allowing lights to operate at the desired brightness, extending fixture lifespan and saving on electricity costs.• Safety Features: Equipped with overload, overvoltage, overheat, and short-circuit protection, ensuring safety for both the user and the connected fixtures.Cons:• Installation may be challenging: The wiring and installation is a little advanced for those that are not familiar with electrical installations.________________________________________Summary:The TobeBright 12V-24V Double Dimmer Light Switch offers impressive functionality with its ability to independently control two lighting circuits and provide a smooth dimming experience across a wide brightness range. Its energy-efficient design helps reduce power consumption and extend fixture life, while built-in safety protections ensure reliable operation. However, the installation process can be challenging due to tight wiring space and inconvenient screw placements, requiring extra precision and care.________________________________________Final Thoughts:This dimmer switch excels in performance and energy efficiency, making it an excellent choice for RVs, motorhomes, boats, and other 12V lighting setups. If you're comfortable with a slightly finicky installation, this dimmer switch delivers solid performance and reliable results.________________________________________Amazon Vine Program:“This is a review of a product received for free via the Amazon Vine Program.

It was a super easy install and It looks fantastic. Dims our coach lights on a 12v system.

I bought three for a project. A choose this one for the appearance and the ALUMINIUM mounting plate. But there are some issues to know. First: there are four wires to connect for three connectors. In the middle hole two wires need to be connected and wires for 10 Amps bearily have not enough space to get it done. Using ferules is impossible. There should have been four connectors. Second: in order to connect the wires, the controller needs to be disassembled from the aluminum plate as the screw holes of the connector face the AL plate: inconvenient. Third: the two mounting/screw holes on the Aluminum plate are located very close to plastic cover of the controllers, letting at the most 3-4 mm space for the screws for fixing. Therefore a very precise hole needs to be cut to have at least 3 mm material for the screws to put in. Pre drilling for the screws is a must otherwise the wood panel will crack due to the thick screws. The controllers work well but don't dim to 0%, but that is mentioned in the description.

The dimmer is very compatible and matches perfectly with my LED fixtures.

Works well in my caravan, worth the money
