These LED Illuminated Triangle Pushbuttons are reminiscent of 1960s or 70s Sci-Fi control board buttons, known for their retro-futuristic triangular shape. Each button is medium-sized for easy pressing yet compact enough for project panels.The button body is black plastic with a built-in white LED that can be controlled separately from the switch action, allowing various lighting configurations. Built-in white LED with approximately 2.2V forward voltage requiring a 220 to 1000 ohm resistor for use with 3V or higher power supplies. Separate switch contacts and LED contacts enable independent control. Non-latching, momentary pushbutton switch design. Recommended to replace the included non-diffused LED with a diffused 5mm LED for improved aesthetics. The button's four contacts consist of two for the switch (normally open, connected only while pressed) and two for the LED (+ and -). This design facilitates varied lighting effects, such as lighting when pressed, always lit, or off.Ideal for creating hexagonal button arrangements or individual retro-style control setups.Technical Details:Wiring DiagramNote: LED is non-diffused and may be replaced for better visual effect.
