Wiring Diagrams for Wall Switch and Outlet

Electrical Question: I am trying to install a combo switch outlet to an original single switch box.

  • The switch will control the lights over two sinks and the outlet to be always hot.
  • I have three pieces of pipe coming into the junction box, and I have a black and a white white, one has black and white wire and an orange wire.
  • All three wires are tied together.
  • All three black are tied together with a pigtail.
  • Originally back pigtail went to the brass screw, and the orange went to the silver screw.
  • I have tried every configuration with the new switch and cannot get the desired results.

Any suggestions?
