Form A contacts ("make contacts") are normally open contacts. The contacts are open when the energizing force (magnet or relay solenoid) is not present. When the energizing force is present, the contact will close. An alternate notation for Form A is SPST-NO. Ver mais An electrical contact is an electrical circuit component found in electrical switches, relays, connectors and circuit breakers. Each contact is a piece of electrically conductive material, typically metal. When a pair of contacts … Ver mais Contacts are rated for the current carrying capacity while closed and the voltage breaking capacity when opening (due to arcing) or while … Ver mais Contacts can be produced from a wide variety of materials. Typical materials include: • Ver mais A normally closed (NC) contact pair is closed (in a conductive state) when it, or the device operating it, is in a deenergized state or relaxed state. Ver mais The National Association of Relay Manufacturers and its successor, the Relay and Switch Industry Association define 23 distinct forms of electrical contact found in relays and switches. Of these contact forms, the following are particularly common: Ver mais When relay contacts open to interrupt a high current with an inductive load, a voltage spike will result, striking an arc across the contacts. If the voltage is high enough, an arc may be struck even without an inductive load. Regardless of how the arc forms, it … Ver mais Ragnar Holm contributed greatly to electrical contact theory and application.
