When you talk of the reed switch, there is a need for you to understand that it has double contacts which are usually magnetic and they are very flexible. All these are usually found in a tube that is made of a glass which is quite fragile. There is a very crucial gas which is usually associated with the reed switches or rather used in the fragile tubes which are used hand in hand with the reed switches. There is a particular mechanism in which the reed switches operate using, and so, it will be proper for you to make sure that you are having a very clear understanding of the whole process. This will give you an ample time once you decide to make use of this given switch at any given time. Read through this page and get all the explanation of the reed switch works.
You will find that those blades which look like the reeds are usually separated when they are in a position that is normal and very open. The fragile glass is usually full of inert gases. The blades will stay when they are ever separated as long as you are not bringing anything close to them, which will attract them, for instance, a magnet. Any kind of a magnet can be used here regardless of its shape as long as it is very effective and it has both the north as well as the south pole.
Once you point a magnet towards it, be it from any direction, you will realize that the blades will come together and try to have that given circuit which is electrical completed. Here, there will be a continuous flow of the currents, and the energy is transferred along this particular circuit which has just been completed. This is when you can see that the tubing is producing some very bright light.
In a case where you get to remove that particular magnetic switch again, you will see the contacts separating and going back to their original positions. At this point, you will learn that the circuit is open again, and there will be no flow of current. This is because these contacts will have nothing which they will get attracted to and so, there is nothing that will pull them together. This is the whole mechanism that the reed switch uses when it is working daily.
