An electrical contact is also called a contact tip, point, button or terminals. It is an electrical circuit component found in electrical switches, relays and breakers. It is composed of two pieces of electrically conductive metal that pass electrical current or insulate when the gap between them is closed or open. The gap must be an insulating medium of air, vacuum, oil, SF6 or other electrically insulating fluid. The electrical contacts may control the power directly or indirectly, switching electrical power through a relay or the supply of natural gas or fuel oil through an electrically operated valve.
2. Application of electrical components auto parts
Silver Electrical contact mainly used small and medium-sized current contactor, starter, temperature controller, switches, etc. undercurrent contact devices, micro switches and precision instruments. 3. Main Materials for electrical components auto parts
