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.
What else can I help you with?
Does etching remove material?
Yes, but the etching solution and type to be used depends on the material
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?

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).
What is fast transfer switches?
Fast transfer switches are devices used to maintain a constant power supply to a device. These are used in many manufacturing and refining companies, were losing power can result in damage to the product, and equipment producing it. They assure that if there is an issue with power on one line, it automatically switches to another to keep things running.
Which material is used for making plugs and switches?
mud and fibers

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.
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) .
Type of magnetic material used for small motors?
ferromagnetic material
