Littelfuse, a diversified industrial technology manufacturing company, launched the TLSM series for surface mount technology (SMT) on May 22, 2025. The design has an ultra-long life of up to 2 million times, a compact 3.45mm height, and a single-pole double-throw (SPDT) configuration that provides greater circuit flexibility and supports complex and diverse application scenarios. It supports a wide range of voltages (DC 1 V-16 V) and currents (10 µA-50 mA), and is compatible with a variety of low-power applications, making it one of the most durable tactile switches on the market.
The TLSM series can be widely used in Industry, Transportation, Consumer electronics, and Medical equipment.
“The TLSM Series reaches a new level in both precision and durability,” said Gavin Xu, engineering technology development manager for the Electronics Business Unit at Littelfuse. “Its compact design, ultra-high sensitivity and long service life provide unmatched reliability for game controllers, tram control panels, medical devices and more. Designed for seamless SMT integration, the TLSM sets a new standard in performance and versatility.”
