[T] - Momentarily button - red LED

A chrome-plated button with red LED ring - momentarily

This metallic button is chrome plated, robust and "weatherproof". Note the use of Weatherproof (not WaterProof), this means it is moisture resistant (caused by weathering) but not "WaterProof" (water resistance and direct splash).

Behind these sealing considerations, you will also find a button with a really cool look and finish offering a pro style to your assemblies! Drill a 16mm hole in any material up to 12.5mm thick and the button will fit. This button comes with a rubber gasket to prevent water seepage into the case. The front of the button has a flat surface (also metal) which is a switch surrounded by a plastic ring for the LED display.

The back is equipped with 3 contacts for the button (common, normally open and normally-closed) and 2 other contacts for the LED ring (+ and -). Connect a 3-6V power supply to the LED to see it light up, the push button contains a resistor to limit the current to the LED! If you want to use a higher voltage, like 12V or 24V, just add a 470 ohm resistor in series with the LED to keep the LED current at around 20mA.

This push button contains a normally open contact and a normally closed contact. If you press the button, the normally-open contact is connected to common as long as the button is "pressed". When you release the button, it returns to its original position and the normally-open contact is "open" again.

The push button and LED are separate, so you can plug it in to turn it on when your rig is powered up (and vice versa) or control the LED as you wish (blinking, pulsing, etc). See the technical details for more information!

What is awesome about this product is that: 

1. 1. The push button includes a normally open contact + a normally closed contact (which reverse).
      This is rather rare in the consumer product.
   2. There is no connection between the LED circuit and the push button.
      You can therefore cut a "high voltage" circuit while the LED is supplied with a 5V PWM signal from your microcontroller (to make the LED pulse... like on modern computers).
