Review on 🔊 APIELE 16mm Momentary Speaker Horn Switch: 12V, 1NO 1NC SPDT, Pre-Wiring Socket, Green/Silver Shell by Robert Toomey

Many reviews say that the wiring diagram is wrong. Which is good because it's wrong. The schematic shows this in colors that don't match my connector, and a connector that isn't the same as the one I have, but is commonly and usually reverse closed, like here (ignore the underline, Amazon doesn't like spaces) : ___+C NO NC___-C means common which is your battery or ground for your horn depending on how you connect it. NO means normally open, which means you press the button to activate that wire. activated when no button is pressed + that's power for the LED (that's all, just for the LED) - that's ground for the LED (that's all, just for the LED) The connector I have is rather so and Common and NC are on the switch "reversed" (ignore the underscores): _______+NC NO C_______- I made a breadboard and here is a picture of how to wire it if you want that Buzzer beeps when a button is pressed.
