What is the right angle tact switch with led

A right angle tact switch with LED represents a pinnacle of integrated electronic design, seamlessly fusing two crucial functions: a tactile push-button mechanism for precise circuit manipulation and an LED (Light-Emitting Diode) for immediate visual status feedback. Commonly referred to as illuminated tact switch, LED tact switch, or illuminated tact push button, this component features a distinctive 90-degree configuration. This design addresses a persistent challenge in electronics engineering—the scarcity of vertical space—making it the optimal choice for horizontal PCB (Printed Circuit Board) mounting, where traditional vertical switches prove too cumbersome or impractical.

At its functional core, the switch operates on a highly sensitive tactile mechanism. When a user applies gentle pressure (ranging from 100-500 grams, depending on the model), an internal metal dome or spring collapses, creating a momentary electrical connection. This instant circuit activation triggers specific actions, such as powering a device on/off, adjusting settings, or enabling features. The satisfying "click" sensation provides tactile confirmation, a hallmark of quality tactile switches. Complementing this, the integrated LED functions on minimal current (usually 10-20mA), emitting either a steady or pulsating light to convey status information: a bright glow indicates an active circuit, a dim light signals standby mode, and the absence of light denotes disengagement or power-off. This dual-purpose design streamlines PCB layouts by eliminating the need for separate switches and indicator LEDs, reducing component count and lowering overall assembly costs.The illuminated tact push button's key features further elevate its appeal. In addition to its compact dimensions (ranging from 3mm to 12mm in length, with ultra-mini variants as small as 2mm for micro-devices), it offers remarkable durability, with lifespan ratings spanning 100,000 to 1,000,000 presses—ensuring reliable performance even in high-usage scenarios. The LED component also allows for extensive customization, with manufacturers offering a wide range of colors: red for alerts, green for active status, blue for a modern aesthetic, amber for low-power indicators, and dual-color options for multi-status signaling.
