First Post: Looking for an electric lever.

[jlovett01]

Does anyone know of anything that flips a little lever when you send a current through it, then flips it back when you stop sending current?

Something like this:

_____
No current: _/

_
Current: \_____

_____
No current: _/

_
Current: \_____

Basically everytime you send a current to this little gadget it flips a lever, then when you stop sending current it flips back.
Any help would be GREATLY appreciated. This is for a school project and it really means a lot to my workgroup.

Thanks,
John

EDIT: sorry about the failed ascii art. It's supposed to give the idea of a lever flipping when current passes into the gadget and flipping back when current stopped.

You might be looking for a reed switch. A reed switch is a type of electrical switch that uses an enclosed chamber and two thin metal strips (or "reeds") that close when a magnetic field is nearby, or close when electricity passes through them. When the current stops flowing, the reeds return to their original position. This makes them useful for many applications, including doorbells, alarms, and robotics projects.
