(SiS) was established in October 2011, specializing in spring fingers &The company that designs, tests and manufactures high-current connectors moved to Chang'an Town, Dongguan in May 2018. The company has CNC lathe workshop, spring finger workshop, assembly workshop, laboratory. Based on the increasing requirements of connectors for high-current connectors in various industries, spring in the spring electronics has developed a new type of bidirectional coil spring finger (SiS®), single-turn spring finger, Constitute multiple array-type deformation contact points (up to more than 300 points).
