Structure	Ball beads structure	Sloping structure	Perforated structure	Claw structure
Contact impedance	≤ 10mΩ	≤ 30mΩ	≤ 50mΩ	≤ 5mΩ
Long service time	10000+	10000+	10000+	500+
Recommended working current	10A max	10A max	10A max	10A max
Main application areas	Mainly used for charging and condition with certain requirements for vibration and shock	Mainly used for charging or signal transmission of Consumer electronics	Mainly used for signal transmission or grounding antenna,etc.	Mainly used high-frequency,anti-instantaneous,the situation which high-reliability is required,such as base stations,military industries,vehicles.
Remarks	The beads increase the internal contacts,the contact is more stable,and the more needle space is required	The most commonly used structure on the market	The space is smaller,but the contact is not stable,the current is easy to run through the spring,and it is not recommended for charging	The needle and the needle tube have multiple contacts to increase the contact stability
