Copper is used as a substrate of the contact meterial; on the grounds of cost; but the actual contacts themselves may be made of silver. Silver does not corrode a badly as copper, and a well designed switch will have a 'wiping' action in its operation, for this prolongs the life of the contacts.
In corrosive atmospheres, such as Rotorua, New Zealand, there is a quantity of H2S in the atmosphere, and platinum contacts are often used.

Does etching remove material?
Yes, but the etching solution and type to be used depends on the material
Is Mercury a conductor or an insulator of electricity?
Mercury is a fair conductor of electricity , although it is a poor conductor of heat.
Why carbon brushes are used in DC machines?
Carbon brushes used in DC machines because carbon is soft material and it does not generate spikes when contact with commutator
What kind of switches are commonly used in Pam multiplexers?
fets are used due to their high speeds
What is transistor mos?
Metal Oxide Semiconductor. Usually used when referring to a specific type of transistor which uses this type of semiconductor material: the Field Effect Transistor (FET).
Which material is used for making plugs and switches?
mud and fibers

A type of hardware device that can be used to interconnect networks?
Switches
What type of RJ45 UTP cable is used between switches?
Crossover cable
Which type of vibration sensor is used for car accidents?
They use inertia switches.
What type of connector is used to connect hubs and switches?
Nowadays, a USB cable connection is commonly used.
How many switches are there?
15 types of
Micro switches are used for what purpose?
Micro switches are small snap-action switches generally used in some type of electronic circuit for some type of repetitive motion. In an air conditioning unit, a micro switch might send a signal to turn the compressor on or off when a room reaches a certain temperature.
Type of magnetic material used for small motors?
ferromagnetic material
What is SMART used for?
a smart material is a type of material used that can be changed by some of its own probities
What is the most important parameter to give low contact resistance?
A good electrical contact requires a clean metal to metal surface, and sufficient force to bring these clean surfaces into intimate contact. Gold is often used as a plating for contacts to aid this function. In some sealed environment switches, mercury is added to reduce the contact resistance (magnetic switches) .
What you understand by the term intrinsic semiconductor and how an intrinsic semiconductor is turned into either a p type or an n type material?
An intransic material is a material that have been used in doping process.There are two type of intrinsic material n type and p type.
