This chrome-plated rugged metal pushbutton features a built-in RGB LED ring light and a latching on/off mechanism. Press once to latch on, press again to release — unlike momentary buttons, it stays in position. Simply drill a 22mm hole into any panel up to 6mm (1/4") thick and secure with the included rubber gasket for a water-resistant fit.
The switch and LED are electrically separated, so you can independently read the switch state and control the LED colour using a microcontroller with PWM on the RGB pins.
Key Features
- 22mm Panel Mount – Fits panels up to 6mm thick with included rubber gasket
- Latching On/Off – Press to latch, press again to release
- RGB LED Ring – Full-colour illumination with built-in resistor (3–6V direct drive)
- Dual SPST Switches – Normally-open and normally-closed contacts (electrically separate)
- Chrome-Plated Metal – Rugged, professional appearance
- PWM Compatible – Mix any LED colour by driving the R, G, B cathodes
Wiring Guide
- RGB LED: 1 anode (3–6V) + 3 cathodes (R, G, B — pull to ground to illuminate)
- Switches: 2 inner spade contacts (normally-closed) + 2 outer spade contacts (normally-open)
Ideal For
- Control panels and custom enclosures
- Power on/off switches with status indication
- Microcontroller-driven RGB status buttons
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.
