Spring-in-Spring Socket Contacts & Connectors

Socket structures with two nested springs (SIS) for high-reliability, low-insertion-force connections. Advantages include high contact power density / multi-point contact, service life up to 100,000 insertion cycles, easy installation and replacement, high current-carrying capacity with low temperature rise, low insertion and extraction force, low voltage drop, and high vibration and shock resistance.
