Wiring diagram for intermediate light switch. The source is at sw1 and 2 wire cable runs from there to the fixtures. In some countries the four way is called an intermediate switch. Light switch wiring diagram with power from the circuit breaker panel going to an electrical receptacle outlet and then continues to the next outlet and then to a single pole wall switch and then to another outlet. Multiple receptacle outlets can be connected with lighting outlets as depicted in the above light switch wiring diagram. You would just continue from one 3 way switch box with the 143 three conductor cable two colored traveler wires a white neutral and a bare or green ground wire in and out of each four way switch box. Here we have a 3 way switching lighting circuit sometimes called two way switching with intermediate.
The hot and neutral terminals on each fixture are spliced with a pigtail to the circuit wires which then continue on to the next light. The four terminals of intermediate switch construction and its operation are shown in fig below where the 4 contact points may be known as a b c d. This allows a single light to be turned on or off from any of the switches. This diagram illustrates wiring for one switch to control 2 or more lights. When the switch knob is up the terminal contacts of intermediate switch connect terminal a with terminal c and terminal b with terminal d as shown in fig 1a. This page shows it wired in the old cable colours if your house has the new colours you want to go here.
