Which site can provide me information on different types of switches,their working and applicatons?

Question

I need information on construction .working,applications of different types of switches such as toggle switch, microswitch,push button switch,rotary switch,slide switch,thumbwheel switch

Answer 1

An electrical switch is any device used to interrupt the flow of electrons in a circuit. Switches are essentially binary devices: they are either completely on ("closed") or completely off ("open"). There are many different types of switches, and we will explore some of these types in this chapter.



Though it may seem strange to cover this elementary electrical topic at such a late stage in this book series, I do so because the chapters that follow explore an older realm of digital technology based on mechanical switch contacts rather than solid-state gate circuits, and a thorough understanding of switch types is necessary for the undertaking. Learning the function of switch-based circuits at the same time that you learn about solid-state logic gates makes both topics easier to grasp, and sets the stage for an enhanced learning experience in Boolean algebra, the mathematics behind digital logic circuits.



The simplest type of switch is one where two electrical conductors are brought in contact with each other by the motion of an actuating mechanism. Other switches are more complex, containing electronic circuits able to turn on or off depending on some physical stimulus (such as light or magnetic field) sensed. In any case, the final output of any switch will be (at least) a pair of wire-connection terminals that will either be connected together by the switch's internal contact mechanism ("closed"), or not connected together ("open").



Any switch designed to be operated by a person is generally called a hand switch, and they are manufactured in several varieties

Answer 2

Not too long ago, I hired a contractor(on L.I.,N.Y.) to install large tiles in my foyer and baths. I selected the tile, called the contractor and he picked the tile up, told me he got a 25% discount on the tile, and gave me 1/2 off (12.5%) on the tiles, plus I had to pay for the labor, which I got a senior discount of 10%. The tile store would have given me a 5% discount on the tile, so altogether, I wound up getting a 22.5% discount. Not bad, I'd say.To answer your question about the type of license determining how much discount a contractor would get. Not so. The larger the quantity of tile orders a contractor will give to a tile establishment will afford a higher discount, I'm told.
