Electrical Contact Pads

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.

Electrical contact pads.

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 preload function nearly doubles the working area of a common spring finger and increases contact force by 0 2n. Mil spec certified contacts meet u s. Refractory contacts contact tips buttons and rivets.

Heating pad electric heat pad for back pain and cramps relief electric fast heat pad with 6 heat settings auto shut off machine washable 12 x 24 4 4 out of 5 stars 2 293 24 99 24. 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. The holes increase soldering strength and reduce solder wicking issues. Plated coated contact brush or base metals are plated or coated with a conductive material.

In contrast as the refractory metal content increases contact wear decreases and there is less likelihood of contact. An electrical contact is an electrical circuit component found in electrical switches relays connectors and circuit breakers. Harwin surface mountable contact pads are perfect as a mating area for spring contacts spring loaded contacts and spring loaded contact connectors. Suitable for shielding grounding mobile phone antenna and other general electrical connection applications.

The dimple on the contact enhances the contact force. We can also produce tips buttons and a wide range of refractory electrical contact solutions. Since 1978 we ve been specializing in high current systems and today we ve become an international group. Contacts for surface mount placement individually or in patterns with internal springs or inherent spring properties.

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. The backward vended tip prevents hooking. Try cleaning the contacts with a micro brush and contact cleaning solution if it s not too dirty. Spring contacts single smt contacts and mating pads.

You can t clean an electrical contact with water but there are some products that are safe and effective. When the pair is. These versatile pads feature a gold finish for improved wear resistance and come in 3 shapes with a choice of pad dimensions.
