Waterproof Metal Pushbutton with Green LED Ring - 16mm Green Momentary (ADA560)

This is a placeholder topic for “Waterproof Metal Pushbutton with Green LED Ring - 16mm Green 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 green plastic LED ring. On the back there are 3 contacts for the button (common, normally-open and normally-closed) and 2 for the green 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.

which of the nc1, no1, and c1 are the input and output on this switch?

Hi Jaspar,

Generally contacts on switches labelled like that correspond with the following

  • NO means Normally Open, this means that when the button is not pressed, the circuit between that pin and the common pin is open (not connected)
  • NC means normally closed, this means that when the button is not pressed, the circuit between that pin and the common pin is closed (connected)
    *C usually means common, in that it is shared by the two pins mentioned above.

As this switch has an LED on board, there will be two more pins that accept power for the LED. Light Emitting Diodes, like any diode, will only allow current to flow one way, so plugging it in correctly will be important.

Keen to see how you go, and let us know if you have more questions!
