Am looking for manufacturer of an unusual terminal/connector block.
As examples of what i am NOT looking for a
1) The "standard" type that "everyone" seems to make - see
PhoenixTerminalBlock.JPG; objection here is that the wire is held down
by a screw clamp.
2) The closest to what i am looking for is similar to the garden variety
wall outlet where the wire is pushed in and held by a spring-loaded
clamp (slot available to release the clamp).

What i am looking for is similar to the Phoenix, but the wire clamp
mechanism is like a lever; lift up, then push in stripped wire, then
push down to clamp; it seems to latch in that position as it is damn
near impossible to lift enough to release the wire.

Suggestions?
