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.
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.
How is electrical contacts installed on an MS connectors?
Normally, wires are connected to MS connectors via soldering [on aircraft as far as I know, although I am trying to find out about other methods].
What are the two major differences between a mechanical switch and a transistor?
speedsizeswitch has moving parts, transistor has no moving partsswitch contacts wear out from friction and/or electrical arcs, transistors don'tetc.
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 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 porpose of condeser in vehicle?
Simplified, it acts as an electrical shock absorber for the Contacts and stops them from "burning out"
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 ment by relay?
It is usually an electro-mechanical device where a solenoid opens and closes electrical contacts.
What do the horizontal lines on an ekg measure?
The horizontal axis is time. The vertical axis is a measure of something electrical (the wires are connected to electrical contacts on your chest).
