Its called a bi-metallic switch, which switches off when the kettle boils, as the switch is made from two layers of different metals, which expand at different rates when heated, which causes the sandwich of the two metals to "bend" when it heats up.

Why can nitinol be used as a switch to switch off a kettle when it gets too hot?
Because when it is heated up, it returns to its original shape, meaning the switch would ping back up and stop the kettle from boiling any more. :)
What type of switch would be used to control a lighting load from one control point?
In this type of situation, where there is more than one lighting circuit, a lighting contactor would be used. These types of contactors can be obtained in four and five pole configurations. Make sure that the contactor is rated for lighting loads and not motor loads. A normal switch, single pole single throw, would be used to switch the contactors on and off. A single switch could then be used to control as many contactors as you need to operate the lighting circuits.If there is just one lighting circuit, the total circuit amperage must be known, then the switch would be sized to the amperage of the circuit.
Where can a circuit with two lamps with single pole switch fluorescent lamp with two 2 way and an intermediate control can be used?
This type of circuit would never be used. The two way fluorescent system would depend on the voltage being supplied by the two lamp circuit switch. If the switch turns off the two lamp circuit the rest of the circuit with the fluorescent fixture would become inoperable.
Which chemical is used to remove scales in an electric kettle?

Can a 4-way switch be used like a single pole switch. if so how is it wired?
Are you sure. They no longer produce a single pole switch in the color needed and we thought that a 4 - way could be sub'd. There is no reason that it would not work, electrically. The problem may be that it doesn't meet electrical code. If you use two terminals on the same side of the switch as you would with single pole, it should work.

How does the switch of an electrical kettle saves energy?
Compared to leaving the kettle on and hot all the time, it certainly saves electrical energy if the kettle is turned off when it's not in use. The switch can be used to perform that vital function.

Why does a kettle sometimes make a loud click as though it's just boiled when it hasn't been used for hours?
It's just contraction. The metal continues to cool and makes cracking sounds. Can happen long after use, especially if there is still water in the kettle.Kettles use a thermo bi-metal switch to shut the kettle off once it has boiled. This switch will not reset while the kettle is hot. Once the kettle has cooled down to a reasonabletemperature the switch will reset itself and be ready to for the next heating cycle. The click you are hearing is the switch resetting itself.

What is a kettle drummer?
Kettle Drums, or Timpani, are large drums that are named for their shape, which looks like a large copper kettle. A set of these drums would be more than one often in differing sizes. Kettle Drums are used in different musical applications such as: Bands, Orcestras, and Percussion ensambles.
