A triangle-shaped momentary pushbutton with a built-in LED, giving your control panels a distinctive retro sci-fi aesthetic. The LED and switch contacts are electrically independent, so you can control illumination separately — light it when pressed, when not pressed, always on, or always off.
The blue translucent triangle cap sits in a black plastic body with four pins: two for the normally-open switch and two for the LED (marked + and −). Arrange six together for a hexagonal layout, or use individually for eye-catching panel controls.
