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

A better set of instructions and wiring diagrams can be found here. This button seems to be of good quality. Two buttons (one bigger, one smaller) are shown in one of the listing photos. It is the smaller one that I bought. In order to make my fiancé's little Honda Civic sound like a trucker's air horn, I bought this as an addition. Adding a loud air horn for "special circumstances" is why I left her factory horn on, but left the loud air horn for normal use. It seems as though the instructions in the listing photos and their video are a bit confusing, but I managed to figure it out for my purposes, so I drew out a better wiring diagram and added some instruction for anyone else who may need assistance. There are just two terminals on the button for current and ground, which make up The left side is the ignition positive, the right side is the ground side. It was easier and more convenient for me to leave the button light on "always on". An on/off switch was located in the dash that was on only when the key was turned on or the engine was running. The right terminal was then grounded to a metal object somewhere on the dashboard. It is the bottom and middle terminals that serve the switch function. In other words, if your relay or horn is negative-switched, you should put a ground/negative on its Positive will be at the bottom terminal, but if you switch it with positive, a negative will be The relays I used in my designs are just standard 12v 4 pin relays. It is possible to switch the positive and negative connections using pin 85 and 86. The two terminals on the relay are either positive or negative regardless of which is positive or negative. It will not cover wiring a relay, but there is plenty of info on Google or YouTube to figure that out. * (Last note) The wiring was done by me and I provided diagrams to illustrate how I use The light is always "on" and the window is normally open As a result, when the button is pressed, it closes / bridges the bottom terminal with Basically you will receive whatever you put on the bottom terminal if it is connected to the middle It is my sincere hope that this helps you. I like the button, it's a little small, but as soon as you figure out the wiring it works fine.

Basically, I bought this button to go on my 1969 VW Beetle. When used as a horn button, it works well. Considering this button is so small, it's about the size of the tip of your finger, I don't see why it should be lit only when the button is pressed. There is no way to see it since you are holding it with your finger. As far as the wiring diagram is concerned, the one offered online isn't great and none comes with the product. I'm not sure what the gear-like thing on the connector is for. That power is for the ignition, isn't it? That's supposed to be the horn, isn't it? What do you know? Since it is a horn button, why is there no picture of horn as part of it? The way it is wired is basically the way it works. As an HVAC tech, I know just a little electricity, so it took me awhile to figure out how it was wired. Whether you make it or break it will depend on NO and C. As a result, when you push the button the power is released. In the diagram, it is shown that way. This is the light button. I suppose it is green to indicate the button is negative and red to indicate the button is positive. It works well, and I might just be a little slow. I gave a positive review for that reason. A horn symbol should be made out of the gears.

It's a joke that this momentary switch exists! It is extremely small to have a diameter of 16mm. In terms of size, the button is about the size of a dime, and the whole There is very little brightness in the LED light and it looks rather flimsy. Five pins and no instructions are on this switch. There is no information on which pins go where or how to wire this probably will not return it, just to save myself some money. I almost certainly will pay for returning it more than what I purchased it One of the red wires and all four of the black wires that came with it is too short. I will need to solder 5 speaker wires from those 5 so they could all reach the connectors on the horn that I will install. This is going to be a hassle to run five different wiring under my dash just to use the horn button. My best wishes to you!.

What is the purpose of this? I know that all horn relays are constant voltage switched ground, and why do I need six Do you mean that you want to run three horn circuits at the same time? Any guidance you can provide would be greatly appreciated. I did not use it, but I kept it as a conversation piece such as "Hey Larry, you won't believe this. ".

There is no wiring diagram available for this switch, tho it is decent, if a little fragile. Including one is really not that hard, right? This is a way of saying, "we don't There are four black wires on the switch. BUILDING BOATS AS A PROFESSIONAL FEELS GOOD TO ME. The idea of passing along serious wiring errors is wrong for me. The black line is always the ground, and the red line is the power supply. Red wires indicate power feed for this item do not come with it. For some reason, I struggled to even get the horn to work for an hour. I did use a red wire and a new terminal to wire it up. The company is lazily run and I would never buy from them "The 7th picture is a wiring diagram," claims the person who says this. This joke is meant to be humorous. An important customer relationship has been lost. You don't read your own reviews, do you?.

In addition to the metric washer, I added a washer to hold the vinyl in place. My version only has the light on when the button is pressed when the product is pressed, so it looks good. One complaint is probably my own error since I wired it so that it worked what I wanted, but once I installed it and had to remove the wires I found it hard to tell where they went since the dash was too small to easily access them. The next time I visit, I'll keep it in mind.

As all of the others have said, no pin diagram is provided. Unfortunately, I do not see the picture that is supposed to be here. The two pins that close the circuit for the horn have been found using my multimeter. They were the two on the bottom row in the center. The other pins may do something else, I have no idea. In addition to the red wire, there are four black wires. together, which makes it more likely that pins will come into contact with each other. I threw it away and ordered something else instead.
