Technically  the essence of small magnets we found in the circuits of some units of celphones like Nokia6131 and others it is used as a sensor or as a switch to trigged the  display and backlights. I know it is a law of magnetism ..........

But how they conduct?

I hope you can give me others ideas Thank You!!!!!

not sure about the mechanism master probably they are using a hall effect sensor, this sensor sense the present of magnetic field kaya nya nalalaman kung nakasara or nakaopen.

pwede ring may reedswitch/relay(pero malamang hindi kasi maxado malaki yun for mobile phones).

I think how many times mo na rin natanong ito sa ibang forum..at ilang beses na rin nasagot..

hall effect sensor nga or hall effect switch..

try to search topics sa wiki about hall effect sensors para lalo mo maintindihan bosing.

Hindi po yung magnet ang sensor kung may ibang pyesa dun na nagsesense ng presence ng magnetic field.

Ito sya sa schematic..





Physically ito naman po sya..
