1, Three button switches on module control different relays separately. Supports external connect momentary switches, supports wire connections length up to 10 meters/32 feet, of course, you can also connect longer wires, which need to consider the electrical interference of your application environment.
2, Power supply LED indication, LED indication for per each relay action.
3, Operating voltage DC 10V to 15V, Operating current(max.) 100mA. Three power relay SPDT(single pole double throw) switch output, support maximum voltage 250VAC / 30VDC, maximum current 10 Amp(per relay).
4, ABS plastic enclosure, you can use screw mount to wood board or wall, of course, can also be placed on the desktop.
5, High quality screw terminal block. Pitch 5.0mm/0.197". Wire range 26AWG ~ 12AWG / 2.5mm square.
Function Description(Example for channel 1):
1, Connect the DC-IN power supply, PWR LED turn to on, other LED all off, all relay output switches Cx to NOx disconnect and Cx to NCx connected.
2, Click button 1 or external momentary switch 1, LED 1 will turn to on, C1 to NO1 will connected and C1 to NC1 disconnect.
3, Click again button 1 or external momentary switch 1, LED 1 will turn to off, C1 to NO1 will disconnected and C1 to NC1 connected.
4, Continue to click button 1 or external momentary switch 1, the above step 2 and 3 actions will be repeated alternately.
Note: the product no power-off memory function, when the DC-IN is turned off, all the relay switches will return to the original state, Cx to NOx disconnect and Cx to NCx connected.

I used this for cargo lighting in a utility van, brand new van came with one incandescent lamp in the rear of the cargo area. I added LED strips and this module to control them. I am going to add remote switches to this, eventually, and this module will accommodate that as well. I bolted magnets to the back so I could mount it out of the way but still pull it out to access it if needed.

​This relay module arrived in a protective plain cardboard box, and it was in excellent condition when I received it. It included no instructions. I've tested the module and found that it works as expected. Each of the momentary switches performs its function as intended and each of the internal relays toggles as intended. It was connected to a bench top power supply set to 12 volts DC. I've attached a photo showing that when all three relays were activated, the module drew 106 mA, just a hair over that claimed in the product description. I removed four screws on the bottom and pulled out the internals. You can see in my second photo that the module, as expected, uses three independent relays, each rated at 277VAC, 10amps, and 125VAC, 12amps. I'll be using this module to control either 12 volt DC or 20 volt DC components, well within its claimed specs. Since there were no instructions, you may find it helpful to view the image in the product description showing a schematic. I find the schematic accurately describes the way this module works, namely that applying ground to a relay, either through its corresponding momentary switch on the module, or through providing momentary ground through the corresponding "in" connector causes the relay to switch state. Being able to control a relay by providing ground through its corresponding "in" connector is nice because it means that whatever device (e.g. a micro​​controller like an Arduino or a Raspberry Pi) is connected is completely isolated from the 12 volts powering the relay module and whatever voltage the relay module is controlling through the NC/C/NO connectors. And having the on-board momentary switches is handy for providing an override to whatever device is connected to the corresponding "in" connector (assuming the device lets the line to the "in" connector float otherwise). This relay module will be used to control LED strips on my model train layout where generally control will be done by a microcontroller, and occasional override with a momentary switch will be handy.​​

It's well built with good contacts and based on my experience, works well as intended. With that being said, they don't provide a shred of information or paperwork with the controller. Ultimately most people who will use it already understand how it works so I somewhat understand the thought process but I think they missed the mark a bit by not including even a small schematic/instruction sheet.Paper is cheap and printing something simple doesn't cost much. Yes you can look at a picture on the product listing or refer to other reviews where people were kind enough to provide details but that's not going to help you a year down the road when you finally get around to using it and can't find the item listing or those reviews.I would have gone with 5 stars had they provided something and would be willing to edit the review if they decide to do so in the future. The product itself is solid but the lack of details was a bit lazy in my opinion.

This power relay module is designed to upgrade most touch plates and offers three channels for controlling different devices.I've been using this relay module to control my removable LED driving lights, and it has performed flawlessly. The module's sturdy construction seems durable enough to use in vehicles or machines.Pros- The module's compact design and mounting tabs for flexible installation.- It reliably handles the power demands of my LED lights, providing effective control.Cons- This module is not waterproof, take caution in wet environments.BottomlineThis power relay module is a reliable and compact solution for controlling various devices. Its sturdy construction and mounting tabs enhance its usability, making it an easy addition to any electrical setup. Just keep in mind its lack of waterproofing when considering installation locations.I hope this concise review helps others in making an informed decision.
