These chrome-plated metal buttons are rugged and waterproof and look real good while doing it! Simply drill a 16mm hole into any material up to 1/2" thick and you can fit these in place, there's even a rubber gasket to keep any water out of the enclosure. On the front of the button is a flat metal actuator, surrounded by a red plastic LED ring. On the back there are 3 contacts for the button (common, normally-open and normally-closed) and 2 for the red LED ring (+ and -). Connect 3 to 6V to the LED to have it light up nicely, there's a built in resistor! If you want to use this with a higher voltage, say 12V or 24V, simply add a 470 ohm resistor in series with the LED connection to keep the LED current at around 20mA.
This button is a momentary push button, when you press it the 'normally-open' contact shorts to the common contact. When you release it, the contacts open up again.
The switch and LED are separated, so you could wire it to turn on when pressed or vice versa or whatever you wish! Check the tech details for information!

- Sound Effects Button
The idea for this project came when a friend of mine flew over from Western Australia to visit, and during his stopover in Adelaide, he did what any adult would do; visit the airport novelty store and buy some random stuff. It was pretty much all junk, except for this big green dome button which played a different, comic voice saying ‘YES’ every time you pressed it. Simple, but, it entertained us on the drive from Syd...
