Because when a company wants to sell something, they will always have competition with other companies selling the same product. To attract customers the company must lower their price, but if they reduce their price their profits will also be reduced. Hence, they must use a cheaper material to build and that is often plastic. And also cos they are cheap bastards, if this was my worlds, everything would be made from carbon fibre and industrial diamond and polycarbonate..! =D
because plastic is not affected by electricity...or somthing like that same with rubber.
Because they are easy to clean and do not conduct heat xx
because the name would be stupid if they were made out of metal...
Modern light switches are made from plastic, copper, and (maybe) coiled steel springs.
metals are good conductors of electricity. plastic and wood are insulators. they do not conduct electricity
Light switches can be purchased from SparkyDirect, they have a huge range of light switches other websites offering light switches are HomeBase, argos and ebay.
It is dependant on whether the switches are in wired in a parallel or series configuration. If the switches are wires in parallel then both switches would have to be off to turn the light bulb off. Either switch could turn the light bulb on. If the switches are wired in series then both switches would have to be on to turn the light bulb on. Either switch could turn the light bulb off.
Dimmer switches go bad, more often than regular switches.

Switches are made of plastic or bakelite because they don't conduct electricity.
Plastic does not conduct electricity.
Some light switches do have a brushed metal fascia but this is laid on a plastic substrate and the plate is earthed to prevent any chance of electric shock.They are not permitted in bathrooms.

The light switches were made as a way for those to be able to conserve energy created to power lightbulbs

they are made from plastic because plastic doent dent and is light weight

Such switches need to have at least some parts that are non-conducting.
