I have some Pass & Seymour/Legrand switches (and receptacles) that have connection options described on their Web site as follows:
"Exceptionally easy to install, with side or screw-pressure-plate backwiring for line and load terminals.
Two backwire holes per termination add wiring flexibility. Fewer pigtails mean more room in the box."
Can I mix a "looped" connection (wire looped around under the screw head) and one or more back-wired connections to the same terminal on the device, thus providing the possibility of having three wires to the one terminal? What about just two connections, but with one wire under the pressure plate and one looped around under the screw head?
