darn part names! all to much for a newbie like me :)
not that im complaining or anything, but Im trying to find a specific part, Ive got no Idea what to call it or if it even exist, so ill just tell ya what im looking for and if you know what Im talking about please tell me what to look for!:)
basically what I need is some sort of switch that compleates a seprate circut of a diffrent voltage.
(EG Ive got a small current, say about.. 2V, what I need that small current to do is run through a device that compleates a seprate but larger current, say about 12V+.
one way I thought about doing this was to build a simple electromagnet, when the smaller current runs through that, it would pull a lever of sorts into a position that compleates another circut, when the smaller current stops flowing, the switch would return and the larger current would stop
if there is a part that does this, what would it be called and where can I find it?
