Electrical contacts are a necessary part of electrical circuits. Common forms of electrical contacts are contact tips or buttons, contact rivets, electrode blocks or billets, pins or probes, solid rod stock, sockets or receptacles, strips or tapes, sheets or foils, small stampings and tapping electrodes.
Electrical contacts are available with a variety of electrode material, contact probe material and plating or coating material. Based on application requirement, electrical contact manufacturers use copper and copper alloys, tungsten carbide, gold, nickel, steel, silver and tin for manufacturing the electrical contacts.
Some important parameters you must consider before purchasing electric contacts are:
- Electric circuit specifications: operating current and voltage
- Required specifications of electrical contacts: material, shape and dimensions
- Other forces acting on the electrical contacts
- Operating environmental conditions
