Connectors
Spring contacts are electrical contacts with spring characteristics. Other names for them include shield fingers and grounding springs.
They are connecting components. Current flows when the contact on the top touches the other contact.
They do not cushion impacts and therefore cannot be used under heavy loads. They work by following vibrations to maintain the contact point.
It gives them a floating structure, meaning the contact part of the spring contact stays with the other contact even when there are vibrations or impacts along the x-y axis.
We recommend that the surface of the other contact is also gold-plated. Using any other, dissimilar metal may lead to galvanic corrosion.
Please ensure a minimum 1.7mm pitch between spring contacts. There are no other restrictions.
Copper alloy.
One spring contact allows a 3A current through. However, please give thought to heat dissipation in board design.
They are used in products with limited board space, such as smartphones, wearable electronics and headsets.
