This is a placeholder topic for “Waterproof Metal Pushbutton with Red LED Ring - 16mm Red Momentary” comments.
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.

To activate the LED do you need more wires or does it work with the 1 in and 1 out the wire. (Sorry I don’t know how to explain it)
Hey Owen,
Thanks for posting on the forum 
No worries, that’s exactly right, as long as the voltage is between 3V and 6V it’ll light up as there’s an internal resistor. But if you’re sitting at a higher voltage then you’ll need a few hundred ohms in series to it in order to limit the current passing through the LED, the suggestion in the description is around 470ohm for up to 24V.
All the best with your project!
