Description
The LS-13 Hook Switch is a high-durability mechanical switch specifically engineered for telecommunication equipment. Serving as the critical interface in telephone handsets, it detects when the handset is lifted to answer a call or replaced to end a call, ensuring reliable connectivity and signaling.
Built for industrial-grade longevity, the LS-13 boasts an impressive operational life of 1,000,000 cycles. Its robust construction allows it to function flawlessly in extreme temperature environments ranging from -40°C to 70°C. With a low contact resistance (≤0.02Ω) and high insulation resistance, this switch provides the consistent performance required for both residential and high-traffic office or public telecommunication systems.
