When I received the horn button, I was concern since there were no instructions provided or a website to reference. The terminal side of the horn button has hard to see lettering with NO, NC, and C. I went back to the Amazon posting and found the photos to determine which wires went to which terminals. They also provide 5-short wires, 1-red and 4-black, which have to connect to the back of the button prior to installing the button onto the panel, this made it difficult to see which terminal each wire is on. It would've made it easier if they'd provided 5-different color wires or labels on the wires. I put my own labels on each of the black wires so I would know which was which when the button was installed. You will need to know ahead of time, what normally closed (NC), normally open (NO), what is common (C) (the wire to the horn), and which terminal is ground, Also know ahead of time, if you want the light on in accessory mode and the same with the horn or do you want the horn on always and the light only when the vehicle is running. This will determine if it is "NO" or "NC" and which terminals to connect the wires onto. I never did figure out what the 5th terminal was used for so that was an extra wire; however, the horn works well when the Side by Side is off or running and the light only comes on when in accessory/running mode. Again, it's easier if you understand electronics and have an Olm/Volt meter. It will be a challenge if you don't have a meter or some knowledge of electronics.

This push button switch is perfect for car modifications! The red LED light looks great and adds a cool touch. The black stainless steel shell is durable, and the pre-wiring makes installation a breeze. It’s easy to mount and works smoothly for any custom project!

Just wired up my button switch. The video and the directions are wrong. You'll need a meter to check whats wrong. Theres only one malfunction. The hot wire going to the horn is is switched with the ground to frame or horn depending on how you're wiring it. Just switch those two terminals on the switch. Check it with a meter. I just grounded the horn to frame and then grounded the button to the frame then ran a hot wire from the button to the horn. The switch isn't too small, Use a 5/8" drill bit for your hole. Other than that the switch is fine. Works good. Looks nice. Kinda like the way we like our women.

Great button used it for my air horn on el camino love the red light that turns on when lights are on and the click feedback when pressing on button

The Twidec/16MM Raised Speaker Horn Momentary Push Button Switch serves its purpose adequately. With a 5/8" mounting hole, it fits standard installations easily. While it provides basic momentary functionality, some users may find its design and durability to be average compared to other options on the market. Overall, it's a functional switch for those seeking a budget-friendly solution.

simple install

Seems like a nice quality button. One of the listing photos shows 2 buttons (one bigger, one smaller). I got the smaller one. I purchased this for adding a loud trucker air horn to my fiancé’s little Honda Civic. I left her factory horn for normal use, but added a loud air horn for “special circumstances” 😂 this button is for the 2nd air horn. Anyways, as others mentioned, the instructions in the listing photos and their video are pretty confusing, but I figured it out for my purposes and drew out a better wiring diagram/instructions for anyone who may need help installing theirs. The left and right terminals on the button are just the power and ground for the light. Left = ignition positive, Right = negative / ground. I opted for “always on” for the button light. Found a positive wire in dash that was on only when key or engine is on. And then grounded the right terminal @ somewhere metal in the dash. Switch function is the bottom and middle terminals. The bottom is the input for the switch (my 2 photos/drawings shows a positive to the bottom switch in one drawing and a negative in the other drawing) The middle terminal is what goes to your horn/device (or relay) So when you press the button, whatever you put at the “C” terminal (bottom terminal / “3” in my drawing), it will send that out from the middle terminal. So if your horn or relay is negative switched, then you’ll put a ground/negative to the bottom terminal. But if positive switched, you’ll put a positive at the bottom terminal. In my drawings I just used a standard 12v 4 pin relay. Pin 85 / 86 are the positive and negative switches. Doesn’t matter which is positive or negative on those two terminals on the relay. (Not gonna get into wiring a relay, but there’s plenty of info on google or YouTube to figure that out) Last note: I wired this and provided diagrams for how I am using it... light always “on” + “normally open” - Meaning, when the button is pressed, it closes / bridges the bottom terminal to the middle terminal. Whatever is connected to the middle terminal will receive whatever you put at the bottom terminal. Hope this helps y’all. Button seems nice, a little small, but it works fine once you figure out the wiring.
