A rugged, chrome-plated latching pushbutton with a built-in RGB LED ring. Drill a 16 mm hole in any panel up to 6.35 mm (1/4") thick and mount it securely — an included rubber gasket provides a water-resistant seal for enclosures.
The flat metal actuator latches on press and releases on a second press (normally-open contact). The RGB LED ring is electrically separate from the switch, letting you independently control the illumination colour via a microcontroller. Power the common anode at 3–6 V and pull individual cathodes (red, green, blue) to ground — built-in resistors are included. PWM the RGB pins to mix any colour.
Key Features
- Latching Action – Press to close, press again to open (normally-open)
- RGB LED Ring – Common anode with built-in resistors; mix any colour via PWM
- 16 mm Panel Mount – Fits panels up to 6.35 mm thick
- Chrome-Plated Metal – Durable, professional finish
- Water-Resistant Gasket – Rubber seal included for outdoor enclosures
- Electrically Separated – Switch and LED circuits are independent
Specifications
- Mounting Hole – 16 mm diameter
- LED Voltage – 3–6 V (common anode; add 1 kΩ resistor for 12–24 V use)
- LED Current – ~20 mA per colour
- Switch Type – Latching, normally-open
- Contacts – 2 gold pins (switch), 4 pins (RGB LED: 1 anode + 3 cathodes)
- Finish – Black chrome
Jargon buster
Plain-language definitions for the technical terms used above.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
- RGB
- Short for red, green and blue, the three primary colours of light that are mixed in varying amounts to make a wide range of colours. In electronics RGB can refer to an LED or pixel that blends these three colours, or to a colour signal or interface that carries separate red, green and blue channels.
