Product Description

We are the leading manufacturer of the Copper Canted Coil Spring and strip contacts. We devote ourselves to this filed for  over 20 years. We have professional technical engineer to design optimal drawing according to the requirements of the customers and the inner diameter of the spring is from 4.5mm to 250mm. 
Spiral spring is mainly used for HV&MV switchgear components, auto parts, oil exploration and testing equipment, hydraulic sealing and other fields, with multiple contact points, small size, easy assembly and so on.
Each coil can work independently, so that it can correct for large area contact tolerances and surface irreglarities.

Simple parameter is as below:
