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. Here we have a 3 way switching lighting circuit sometimes called two way switching with intermediate.
What Is An Intermediate Switch
Wiring diagram for intermediate light switch. This diagram illustrates wiring for one switch to control 2 or more lights. Multiple receptacle outlets can be connected with lighting outlets as depicted in the above light switch wiring diagram. Intermediate switch related circuit diagrams and wiring diagrams intermediate switch wiring diagram old cable colours intermediate switch wiring diagram new cable colours the intermediate light switch is used where three or more switches control one light and used in conjunction with two two way light switches to achieve this. 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. This allows a single light to be turned on or off from any of the switches.
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. This page shows it wired in the old cable colours if your house has the new colours you want to go here. 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. The source is at sw1 and 2 wire cable runs from there to the fixtures. See the light switch wiring diagrams above and below.
