Hi,
I am working on a system in which I have to use a microcontroller to turn on a switch. So can any of the gurus here suggest which kind of device i have to use?? the switch has to handle currents of less than 4A.. a few frnds have suggested a relay.. but they are quite bulky.. so I am thinking of using a triac (may be BTB04-600SL).. which one should I use?? The system has to work for a long loooooooooooong time. please let me know if you have a better idea/device in mind.
Regards,
Rohan
