Does a current activated switch as small as an OR Gate exist? Answered
I have a type of connector that has two wires. two on one side and two on the other. One of the "connectors/wires" is red with ~5V and the other is white with a varying current/voltage of ~10mV to 3.3V which goes in either direction.
This connector is meant to be plugged in, in either direction. So at any given time, only one side is receiving current. The bottom of the connector if thought of as a box comes into contact with a grounding panel, which shorts out the connector, and it does not function.
What I need is to have a sort of switch, that when activated by current, can "turn" off the bottom pins when plugged in one way, and then the other pins when plugged in another way.
I have thought about it and I can use a simple OR Gate, for the constant 5V, but OR Gates will not work going in two directions or at a varying voltage of 10mV to 3.3V.
I was thinking that perhaps a current activated switch would work, but it needs to be a very small chip, and relatively low cost. Anybody have any ideas? Sorry for the poor picture. I am not an artist. ;) Thanks, in Advance. -Sterling
