Wire Connectors In Switch And Recepticle Boxes

Bob,

How so?
They appear to be the same.

In the back stab devices there is only a thin srip of metal that provides the contact pressure. In Wago and Ideal connectors there is a lot more contact area.

also remember that receptacles are usually subject to more movement, each time something is plugged in or out...

Push in switches and connectors don't (or at least shouldn't) have this constant push and pull over time.

This is one reason why push in receptacles aren't reliable -- but I don't see the same problem with the switches and the connectors.
