Electrical Contact Pads

Refractory contacts contact tips buttons and rivets.

Electrical contact pads.

Spring contacts single smt contacts and mating pads. Since 1978 we ve been specializing in high current systems and today we ve become an international group. Harwin surface mountable contact pads are perfect as a mating area for spring contacts spring loaded contacts and spring loaded contact connectors. You can t clean an electrical contact with water but there are some products that are safe and effective.

Contacts for surface mount placement individually or in patterns with internal springs or inherent spring properties. The backward vended tip prevents hooking. 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. The holes increase soldering strength and reduce solder wicking issues.

These versatile pads feature a gold finish for improved wear resistance and come in 3 shapes with a choice of pad dimensions. Mil spec certified contacts meet u s. Electrical contacts may get dirty with normal use which can affect an item s performance. Suitable for shielding grounding mobile phone antenna and other general electrical connection applications.

We can also produce tips buttons and a wide range of refractory electrical contact solutions. An electrical contact is an electrical circuit component found in electrical switches relays connectors and circuit breakers. 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 preload function nearly doubles the working area of a common spring finger and increases contact force by 0 2n.

The dimple on the contact enhances the contact force. Plated coated contact brush or base metals are plated or coated with a conductive material. Electrical contact or electrodes are manufactured to the desired shape and dimensional specifications through a machining process. 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.

When the pair is. In contrast as the refractory metal content increases contact wear decreases and there is less likelihood of contact. 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.
