This 30mm translucent green arcade button has built-in LEDs for a beautiful illuminated look. Two surface-mount LEDs with resistors are embedded in the button body, ready to light up from a microcontroller pin or direct 5V power at just 10mA draw.
The button screws into place through material up to ~20mm thick, covering any imperfections in the mounting hole. A pre-installed micro-switch with gold-plated contacts provides smooth action with clear tactile feedback. Separate contacts for the LEDs sit next to the switch contacts for easy wiring.
Key Features
- Built-In LEDs – Two parallel SMD LEDs with ~1K resistors each, embedded in the button body
- 30mm Translucent Green – Crystal glossy finish, stunning when illuminated
- Pre-Installed Micro-Switch – Gold-plated contacts for reliable operation
- Smooth Action – Tactile press without a harsh click
- Screw-In Mounting – Fits material up to ~20mm thick, requires 30mm hole
- Low Power – 10mA at 5V, or 2mA at 3.3V (dimmer)
Specifications
- Button Diameter: 30mm mounting hole

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.
- SMD
- SMD means surface-mount device, a component style designed to be soldered directly onto the surface of a circuit board rather than through holes. SMD parts are compact and mounted flat on the board, which suits smaller and mass-produced designs.
