Description

TYPES OF REED SWITCH:-
There are two fundamental types.
1. NORMALLY OPEN TYPE.
In a normally open switch, the two reeds, which are made from ferrous material such as a nickel-iron alloy are positioned so that they are not touching. When a magnet is moved close to the switch, it pulls one of the reeds towards the other so that they are touching, and therefore completing the circuit.
Remove the magnet and the reeds return to their original position breaking the circuit.
2. NORMALLY CLOSE TYPE.
A normally closed switch works in the opposite way, when no magnetic field is present the reeds are in full contact, the electric circuit is complete and the device is ‘on’. When a magnet is moved close to a switch, or the switch close to a magnet, the reeds repel one another and split apart, breaking the circuit.
Applications:-
1. Home Security.
2. Industrial Level.
3. Water Flow Level.
4. Toys
