Twidec/16MM Raised Speaker Horn Momentary Push Button Switch 5/8" Mounting Hole 12V Blue Led Light Black Stainless Steel Shell 1NO 1NC SPDT with Pre-wiring Wires Switch For Car Modification BKG16LB-BU

Button was perfect size for my use to wire a Dixie horn. The wiring diagram given by a previous installer REALLY helped to save time during install. The back lighting is not too bright and I wired it to come on when the park or headlights are on (via the dimmer output for the radio head unit)Happy and would recommend!

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.

Button works great and looks great. Pin out directions are great BUT there isn’t an orientation marking. + and - are the outside pins but which way is up? Had to go to picture on Amazon. Why not make the drawing match hence the 4 stars.

Works like a toggle switch is supposed to. Looks clean and good price

Switch functionality:LED lights up. Switch did not work. Waiting on replacement.

LittleSmaller then I thought it was gonna be but it's well made and looks awesome

Easy to install. Perfect to use. I could have installed on my dash but I made it into something like a jeopardy answer buzzer by tapping up the wires.

After following the instructions and verifying proper installation I tested this button with my air horn. At first it worked properly, but when I put the bolt on the back of it to hold it in its installed location the bolt caused a cross connection and sparked causing the button to shirt out. Guess what? It stopped working. Went to my local auto shop and got a button from there and everything works like a charm. This product looks good, quite small though. Installation instructions are going to be confusing for anyone not used to reading electrical layouts. And the light wasn't very bright all. Quality was poor since it shorted out.
