Editing Light switch (section)

===Power cord mounted===
This type of switch is mounted on the power cord, both in middle or at the end. They are light weight, and they are used mainly for low power devices, like table lamps, table fans, radios and many other low power devices. Usually, they are single pole single throw but can also double pole single throw. They can be mounted either in the middle of the plug and consumer or they may be mounted at the end of the cable. There are also more sophisticated cord mounted switches, like multiple switching (for lamps with more than one bulb, or fans with more speeds, in this case they have one input and 2 or more outputs), variators and dimmers (light dimmers, electric pillows and mattresses  or some fans with more speeds). Some older heaters may also use such switches, but with higher ratings. 
Usually their current rating is between 0.5 A, mainly limited to low powered lamps at mains voltage, up to 6 or even 10 A (like heaters) . Higher current ratings may also allow usage in high current but low voltage (6-24 V) applications.
