THE ELECTRONIC WALL MOUNTED SWITCH AND ITS LOAD EQUIPMENT

摘要

PURPOSE: An electronic wall switch and a load device thereof are provided to exclude a separate communications line by transmitting a signal to a load device through a switch line. CONSTITUTION: A charge part power source circuit block(1) is arranged between an ACin terminal and a triac circuit block(5). An isolated power circuit block(2) supplies un-charged part power source to a microcomputer control circuit block(3) and a 485 communications block(4). The triac circuit block is connected to a space between the charge part power source circuit block and a switch output terminal. The 485 communications block and a phase discrimination circuit block(6) are connected to the control microcomputer of the microcomputer control circuit block.
