Product Overview
The series unifies a high‑brightness LED and a mechanical tact switch in a compact housing, with pins that pass vertically through the PCB and are secured by wave or hand soldering to create a rugged metal‑to‑board interconnection. Unlike surface‑mount alternatives, these through‑hole pins behave like rivets anchored in the board—dramatically lowering the chance of solder‑joint failure even under repeated presses, mechanical shock, or thermal cycling. At the same time, the integrated LED emits a uniform glow from the center or rim of the keycap, giving users instant visual feedback and clear guidance in dimly lit environments.
Technical Parameters
Key Features:
1. Through‑Hole Anchor Structure：
Adopting standard THT (Through‑Hole Technology) pin design, the pins pass through PCB plated through‑holes and are soldered on the back side. Solder fills the hole walls to form 360° encapsulation, providing much higher pull‑out strength than surface‑mount solder joints, and ensuring electrical connection integrity even under vibration, shock, or long‑term mechanical stress.
2. Optoelectronic Integrated Assembly：
The LED light source and switch contacts are encapsulated within the same precision housing, eliminating the need for additional lamp holders, light guides, or independent current‑limiting circuits. The keycap is made of high‑transmittance engineering plastic or employs laser‑engraved light‑guiding technology, delivering uniform and soft illumination without harsh hot spots.
3. Multiple Color Temperature LED Options：
The built‑in LED supports standard single colors such as red, green, blue, yellow, and white, and can also be configured as bi‑color common‑cathode/common‑anode or RGB full‑color solutions. Different color temperatures can be mapped to various device statuses—for example, red for alarm, green for operation, blue for standby—enabling screen‑free status communication.
4. Dual Soldering Process Compatibility：
The pin material and plating are optimized for both wave soldering in high‑volume production and manual soldering with electric irons for repair and prototyping. The plating offers excellent solderability with a small wetting angle, minimizing the risk of cold or insufficient solder joints.
5. Multiple Heights and Actuation Forces：
Keycap heights range from low‑profile (approx. 4.3mm) to tall‑dome (approx. 11mm and above), with actuation force options such as 160gf and 250gf commonly available. Engineers can freely select according to panel thickness, operating frequency, and anti‑mistouch requirements.
6. Wide‑Temperature Noble‑Metal Contacts：
The dome or spring is made of high‑elasticity stainless steel or phosphor bronze, with a gold‑ or silver‑plated surface. The noble‑metal plating effectively suppresses micro‑arcing and oxidative corrosion under the signal‑level currents typical of through‑hole switches, ensuring stable contact resistance across a wide temperature range from –40°C to +85°C.
Applications:
1. Industrial Control & Automation：
Manual operation panels on PLC control cabinets, parameter setting keys on variable frequency drives, and emergency stop/reset buttons on CNC machine tools. The vibration, dust, and electromagnetic interference in industrial environments impose stringent demands on component reliability—here, the ruggedness of through‑hole soldering and the intuitiveness of illuminated indication form an optimal combination.
2. Prototyping & Education：
Arduino expansion boards, Raspberry Pi GPIO experiment modules, and electronic competition kits. The through‑hole pins can be inserted directly into breadboards, allowing students and makers to complete circuit assembly without a hot‑air gun, while the LED provides instant feedback on button status, lowering the learning curve.
3. Medical & Laboratory Equipment：
Power or function keys on centrifuges, incubators, and analytical instruments. Medical equipment often has a service life of over ten years; the through‑hole construction facilitates later maintenance and replacement, while LED status indication helps laboratory personnel quickly identify operating conditions in low‑light environments.
4. Automotive & Rail Transit：
Instrument panels of construction vehicles, control panels in railway carriages, and navigation equipment buttons on ships. Continuous vibration and jolts challenge solder joint integrity—the through‑hole anchor structure provides an extra mechanical safeguard, and backlit keys enhance operational safety during nighttime driving or navigation.
5. Communications & Networking Equipment：
Front panels of server chassis, reset keys on switches, and maintenance interfaces at base stations. Dimly lit cabinets make illuminated buttons essential for operations engineers to quickly locate target switches on crowded panels; the through‑hole design withstands physical shocks during cabinet transport and installation.
6. Home Appliances & Commercial Equipment：
Control panels of commercial ovens, dishwashers, and industrial washing machines. In high‑humidity, high‑temperature commercial kitchen environments, the sealed nature and structural strength of through‑hole solder joints outperform SMD alternatives, while LED indicators ensure operators can clearly identify button functions even in steam‑filled conditions.
