I have a toggle switch that needs replacing but I don't know the proper terms for its mechanical action and any identification numbers have long since worn away. It's a SPDT with center OFF, but you can't move the arm from one side to the other without releasing it at center. The action is this - push to center, release, then push to other pole. I've never come across a toggle switch like this before, and I'm hoping that someone here can help me out with the proper words to give to google.
Thanks

 

This is a type used and sold by KB DC drives and distributors, I think I have one here.
If you have a KB or Baldor DC drive distributor near you, they may carry them.
It is used to prevent switching a DC motor from FWD to REV without a pause for it to stop.

P.H.O.T.O.

 

Max, that's exactly what it's being used for. I'll check out those companies you mentioned, thanks. Any idea on what the proper terminology is for this thing? Here's a picture of it
