 What is reed switch? | how reed switch works?


HELLO FRIENDS.

 

Reed Switch

 

The reed switch is an electrical switch operated by an applied magnetic field.

 

CONSTRUCTION:-

It consists of a pair of ferromagnetic contacts on iron metal reeds in a sealed glass envelope.

When a magnet comes near to this switch, it magnetize the iron reeds and come together to make a contact. This temporary contact works as a switch.

The moment magnet moves away, the switch turns Off and contacts are separated.

  What is RGB LED? | how it works?   HELLO FRIENDS.   RGB LED   An RGB LED, as name suggests is a special LED which is capable of producing all colors by mixing Red, Green and Blue colors . In simple words It consists of 3 LEDs (Red, Green, Blue) together in a package and by variation of these 3 colors more colors can be formed.   An RGB LED is having 4 pins, one of which is a common anode and other 3 pins are for Red, Green and Blue respectively. Or common cathode and other 3 pins are Red, Green, Blue.   So, to distinguish between common cathode and common anode RGB LEDs: Use a multimeter in continuity mode. If the LED lights up with the red tip on the longest lead and the black on one of the other leads – you have a common anode RGB LED If the LED lights up with the black tip on the longest lead and the red tip on one of the other leads – you have a common cathode RGB LED.   By manufactur...
