What Is an LED Tactile Switch?
An led tactile switch combines a momentary tactile switch and an integrated LED indicator in a single compact component. The switch provides a clear tactile click response, while the LED offers visual status indication—on/off, mode, or warning—making it ideal for user interfaces and control panels. This illuminated tactile switch saves PCB space by eliminating the need for a separate LED and resistor placement, simplifies assembly, and enhances product aesthetics.
Why Choose a 5 Pin Illuminated Tact Switch?
Compared with standard 4‑pin tactile switches, a 5 pin tactile switch with LED offers distinct advantages:
- Visual operation indication – instantly see if a circuit is active.
- Improved user experience – light guides the user, especially in dim environments.
- Simplified PCB design – one component replaces two, reducing BOM and routing complexity.
- Compact integration – a smd tactile switch with led fits into space‑constrained designs.
- Enhanced product aesthetics – a lighted tact switch adds a modern, high‑tech look.

Frequently Asked Questions – LED Tactile Switch
What is an LED tactile switch?
An LED tactile switch combines a momentary tactile switch and a built‑in LED indicator within a single SMD component, saving space and simplifying assembly. The TS-1156 is a 5‑pin version of this design.
Why does an illuminated tact switch have 5 pins?
Typically, four pins are used for the switch contacts and mechanical mounting, while the fifth pin connects to the integrated LED circuit. This allows the LED to be driven independently from the switch signal.
What are LED tactile switches used for?
They are commonly used in control panels, consumer electronics, industrial equipment, and any product requiring visual feedback from a push button.
Is this switch compatible with SMT assembly?
Yes. The TS-1156 is designed for automated SMT production and standard reflow soldering processes.
Can different LED colors be customized?
Yes, depending on the product series, multiple LED colors (e.g., red, green, blue, white) are typically available. Contact us for customization options.
Integrating a 5 Pin LED Tactile Switch in Your Design
The led tactile switch represents the next step in space‑constrained user interface design. By merging a proven tactile mechanism with a surface‑mount LED, this illuminated tactile switch delivers both functionality and visual clarity in a single 4.5×4.5×1.5mm package. Whether you need to indicate power states, mode selections, or warnings, the integrated LED eliminates the need for a separate light pipe or indicator, freeing up board space for other components. Designers can choose from multiple operating forces (160gf to 260gf) and LED colors to match the exact feel and look of the end product.
When sourcing a smd tactile switch with led, it’s important to work with a manufacturer that can ensure consistent LED brightness and chromaticity across production batches. Vistar Electronics tests every switch for both contact resistance and LED parameters, providing a reliable lighted tact switch for consumer, medical, and industrial markets. The 5‑pin footprint is fully compatible with standard SMT reflow profiles, and the tape‑and‑reel packaging supports high‑speed pick‑and‑place lines. For products that need IP67 protection, sealed versions are also available on request.
