Electrical Contact Pads

An electrical contact is an electrical circuit component found in electrical switches relays connectors and circuit breakers.

Electrical contact pads.

Spring contacts single smt contacts and mating pads. Try cleaning the contacts with a micro brush and contact cleaning solution if it s not too dirty. Generally as the conductive metal silver or copper increases contact resistance decreases and electrical and thermal conductivity increase but contact erosion and contact sticking or welding become more of a concern. Plated coated contact brush or base metals are plated or coated with a conductive material.

Each contact is a piece of electrically conductive material typically metal when a pair of contacts touch they can pass an electrical current with a certain contact resistance dependent on surface structure surface chemistry and contact time. The pick and place area supports auto assembly processes. Harwin surface mountable contact pads are perfect as a mating area for spring contacts spring loaded contacts and spring loaded contact connectors. Electrical contact or electrodes are manufactured to the desired shape and dimensional specifications through a machining process.

The dimple on the contact enhances the contact force. The preload function nearly doubles the working area of a common spring finger and increases contact force by 0 2n.

When the pair is. The backward vended tip prevents hooking. Our sales network extends to over 40 countries all over the world and we can count on trustworthy collaborators with a wealth of experience who are above all customer. We can also produce tips buttons and a wide range of refractory electrical contact solutions.

Suitable for shielding grounding mobile phone antenna and other general electrical connection applications. In contrast as the refractory metal content increases contact wear decreases and there is less likelihood of contact. Since 1978 we ve been specializing in high current systems and today we ve become an international group. Because of our unique ability to melt cast draw and clad our contact materials checon can custom design cost effective electrical contacts including cadmium free electrical contacts that are stamped or headed from wire strip or ribbon.

The holes increase soldering strength and reduce solder wicking issues. Refractory contacts contact tips buttons and rivets. You can t clean an electrical contact with water but there are some products that are safe and effective.
