Rugged Metal On/Off Switch with White LED Ring - 16mm White On/Off PRODUCT ID: 917 These chrome-plated metal buttons are ru gged 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 water out of the enclosure. On the front of the button is a flat metal actuator, surrounded by a white plastic LED ring. On the back there are 3 contac ts for the button (common, normally- open and normally-closed) and 2 for the white 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 an on/off switch button, when you press it the 'normally-open' contact shorts to the common contact and the button stays 'pressed'. When you press it a second time, the button springs open, and 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!
