## Description

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. Key Features Triangle Shape – Distinctive retro-futuristic design, tessellates into hexagonal patterns Built-in LED – Independent from switch contacts for flexible illumination control Momentary Action – Normally open; contacts close only while pressed Medium Size – Large enough for comfortable pressing, compact enough for panel layouts Colour: Blue Specifications Switch Type: Momentary, normally open LED Forward Voltage: ~2.2 V Pins: 4 (2× switch, 2× LED) LED Resistor: Use 220–1,000 Ω in series with 3 V+ supply Ideal For Custom control panels and dashboards Retro and sci-fi themed builds Arcade and interactive installations Tip: The included LED is non-diffused. For a more even glow, replace it with a diffused 5 mm LED.
