simple Light Switch Triac

By August 22, 2011

The series of light switches this time a little differently in terms of its voltage. The series of  light switches can work directly on the AC power network. Light switches are using the main component of  TRIAC and LDR. The circuit is very simple and its components are also widely sold in the market. If you want a light reception sensitivity of this circuit can be set then the 3.3 MOhm resistor can be replaced with a variable resistor. More detail can be seen from the following schematic .
