Two answers for this question. An electrical contact is any point in a circuit that a wire connects to, such as a screw or terminal block. The term is also used when referring to control circuits. There are contacts inside Relays, Ligthting contators, and motor starters. They can be called N.O. for normally open, and or N.C. for normally closed. They "Make" of "Break" and electrical circuit.
What else can I help you with?
Can you explain how a switch works?
It is an on-off electrical device. When the contacts are closed it starts conducting and, if its contacts open, no conduction can take place.
What is an electrical device which consists of a frame plunger and coil and is used to open and close a set of contacts.?
An electrical device that consists of a frame, plunger, and coil, used to open and close a set of contacts, is called a relay. When an electrical current flows through the coil, it creates a magnetic field that moves the plunger, thereby making or breaking the connection between the contacts. Relays are commonly used in various applications for switching circuits and controlling devices remotely.
Vacuum bottle in vacuum circuit breaker?
Is a breaker whose contacts are in vacum cylinder. this done so the contacts will not be burnt and destroyed by the electrical arc draw while opening under load.Used in high voltage and high amp conditions.
How do auxiliary contacts work?
Auxiliary contacts are additional contacts used in conjunction with a primary switch or relay to provide additional control or indication functions. They operate in synchronization with the main contacts, either opening or closing alongside them as the primary device is activated or deactivated. These contacts can be normally open (NO) or normally closed (NC) and are commonly used in control circuits to signal the status of the primary device or to control other devices in a system. Their versatility allows for more complex control schemes and automation in electrical systems.
What is the purpose of a coil clearing contacts?
Coil clearing contacts are used in electrical relay systems to ensure that the relay coil is de-energized and to facilitate the proper operation of the relay. When the relay coil is energized, these contacts help clear any residual current or voltage from the coil, preventing unintended activation or malfunction. This is crucial for the reliable operation of the relay, especially in applications requiring precise control and safety. Ultimately, coil clearing contacts enhance the overall performance and longevity of relay systems.
What happens when NC and NO contacts not work in electrical panel?
When a NC and NO contacts are not working the NC will not open and the NO will not close.
Why you should use silver?
Silver is one of the best electrical conductors. It is used in a lot of electrical contacts.
Element used to make jewelry wires electrical contacts?

What does LB mean when it is beside contacts on an electrical drawing?
light bollard
Can you explain how a switch works?
It is an on-off electrical device. When the contacts are closed it starts conducting and, if its contacts open, no conduction can take place.
Miller big 40 welder does not work?
USE ELECTRICAL CONTACT CLEANER FOR ALL CONNECTIONS AND FINE EMERY CLOTH ON CONTACTS USE ELECTRICAL CONTACT CLEANER FOR ALL CONNECTIONS AND FINE EMERY CLOTH ON CONTACTS
Why do cars light sockets have a goop in them?
To keep the electrical contacts clean and corrosion free.
What are electrical outlets made of?
Electrical outlets are typically made of a combination of thermoplastics, metal contacts, and internal wiring components. The outer casing is usually made of fire-resistant materials to ensure safety during operation. The metal contacts inside the outlet provide the connection point for electrical devices.
What is the contacts on a steering wheel blown mean?
On older cars the horn has two or more electrical contacts, the "Button" and a slip ring that allows the steering wheel to turn. On more modern cars all the buttons on the steering wheel including things like cruse control stereo etc have electrical contacts. Any or all of these can fail
What is ment by relay?
It is usually an electro-mechanical device where a solenoid opens and closes electrical contacts.
What should be used to clean electrical contacts?
if they are pitted you can use emery cloth and a can of contact clea.ner
What is the porpose of condeser in vehicle?
Simplified, it acts as an electrical shock absorber for the Contacts and stops them from "burning out"
