Littelfuse has launched the KSC XA series of soft-sound touch switches, providing a key solution for applications that require quiet and reliable haptic feedback. The KSC XA switch is specially designed for surface mount technology (SMT) applications, providing an innovative soft sound and bringing a quieter user experience. The expansion cage enables potting compatibility, and the high driving force option ensures precise and meticulous operation. These characteristics make the KSC XA switch highly suitable for industries with higher requirements for noise reduction, durability and reliability, such as automotive, medical, industrial and high-end consumer electronics.

The KSC XA series offers engineers an innovative combination, featuring soft touch feedback, compact size and high environmental tolerance. The KSC XA switch has an IP67 dust-proof and moisture-proof rating and adopts a robust hard drive design to ensure long-lasting performance in harsh environments. Its expansion cage design supports encapsulation with potting materials, providing additional anti-corrosion and environmental pressure protection.

Main functions and features

• Soft sound: Enhance user experience, especially in noise-sensitive environments;

• Expansion cage: Achieve potting compatibility and enhance protection against harsh environments;

• High driving force (up to 9.6N) : Provides precise intentional button triggering to reduce unexpected activation;

• IP67 grade sealing: Ensure durability, moisture-proof, dust-proof and chip-proof;

• Long service life: Up to 1 million cycles, with outstanding reliability;

• J-shaped curved terminal: Supports efficient SMT assembly, simplifying mass production;

• Compact size (6.2 x 6.2 x 4.9 mm) : Highly suitable for applications with limited space;

• Environmentally friendly: Low halogen, compliant with RoHS and REACH standards, and compatible with lead-free reflow soldering processes.

The KSC XA series builds on the success of the multi-functional KSC touch switch series and introduces new standards for soft sound and potting compatibility. Laurent Kubat, the European R&D director for EBU switches and sensors at Littelfuse, said, "These touch switches offer reliable and low-noise operation in a compact form factor and are highly suitable for demanding applications such as automotive steering wheels, smart home devices and surgical instruments." KSC XA offers durable and multi-functional solutions, reducing the need for frequent replacement and ensuring long-term performance for customers.

Target market and application

The KSC XA touch switch is designed to meet various application requirements, including:

• Automobiles: Steering wheel buttons, dashboard controls, window switches and seat controls;

• Medical: Diagnostic equipment, patient control equipment and monitors;

• Industry: Factory automation, test and measurement equipment, and smart electricity meters;

• High-end consumer electronics: headphones, advanced remote controls, smart home devices and ergonomic products.

The KSC XA series combines the quiet operation preferred by users with powerful environmental protection performance, setting a new benchmark for touch switches. It can enhance the user experience while meeting the demands of harsh applications, and this feature makes it an important component of the Littelfuse/C&K product portfolio.
