    How do you wire the source outlet only, to be switched with the remaining four outlets to remain hot all the time.
    I am not interested in splitting the outlet. Ty in advance.

    • Dave Rongey says:

      Hi Pat,
      To control a receptacle outlet from a switch take a 2-wire cable from the outlet to the switch. Create a splice at the outlet to feed the power leg out to the switch and back down to the outlet where the return wire is attached to the outlet. Please see the Wiring Diagrams section of the website for further assistance and visual drawings.
