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.

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 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 is close contact relay?
A relay is an electrical switch. It consists of a electromagnetic coil and a set of mechanical contacts. Depending on the relay their could be multiple sets of mechanical contacts. The close contact lets current flow through the mechanical contacts when the relay is not turned on. When the relay is turned on current flow is stopped. This is called a normally closed contact or NC The open contact works the opposite of the closed and is referred to as a normally open contact or NO
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 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).

What is ment by relay?
It is usually an electro-mechanical device where a solenoid opens and closes electrical contacts.
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
