Pyroelectric proximity switches can sense temperature changes with elements made of switches called pyroelectric proximity switches. This switch is Pyroelectric switch mounted on the detecting surface, when the ambient temperature is close to the different objects, the output of Pyroelectric will change, thus can detect an object approaching.

Then gradually remove the magnet magnetic reed switch, magnetic field disappeared, reed restitution, the circuit is disconnected, the LED goes out. Riot magnetic switch back and forth several times, in line with the above, the measured reed is good. If there are no magnets available external magnetic speaker magnet back instead. If you close the switch K, the light-emitting diodes on the light, or when the magnet is removed, the LED is lit, and when the magnet close, the light emitting diode does not light, etc., it shows that the test has been lost reed switch the role of the line can no longer Liaoyang magnetic switch magnetic switch _ _ Shen electrically by the Shenyang People Electric Co. Shenyang Electric Co. on people (www.zsmsy.com) strong, credible, and other industries in other Shenyang, Liaoning province has accumulated a large number of loyal customers. The company better work attitude and constantly improve the innovative ideas will lead sink into the brilliant electric and you work for a better future!
