I recently built a Toggle switch board based on 555 chip, for those who are interested to build one, i have attached some schematics and PCB design.
The circuit works fine, except "2" little problems which i might rectify with some of your help.
Problem No.1: When I connect power to the circuit, for some reason the relay is engaged instantly (without pressing the toggle switch). This doesnot happen every time i connect the power supply but most of the time.
Problem No 2: In a different scenario when the circuit is connected to the Power and the Relay is disengaged and i start some other electical appliance for e.g. A Vacuum Cleaner or a room heater or my Power amp, starting these appliances somehow engages the Relay automatically (without pressing the Toggle switch). just as above this problem also doesn't occur every time.
Any help or recommendation will be deeply appreciated. Thanks...
Best Regards,
