You may be switching a high current, voltage, low level signal etc.What do you mean "what are the relay contact being used" ?
This PDF is the for the type you posted.i don't think it's the same table that i sent in the link but i understand what you wrote ,
You could use a device that was specifically designed to interface with a power device with a PIC etc, namely the 2n7000 'Fetlington'.Hi all,
I see many circuits over the internet of a PIC controlled Relay,
what are the differences and considerations of choosing the right transistor for this kind of circuit ?
DC Source : 5vots
Relay : 5volts
Thanks !
You need to choose the relay before you choose the transistor.Hi all,

FETlington? What a sales pitch!You could use a device that was specifically designed to interface with a power device with a PIC etc, namely the 2n7000 'Fetlington'.
Cheap and has the advantage of not loading the μp.
