Intermediate Switch Wiring Diagram. This video shows how to wire a three way lighting circuit this means that you can have three separate switches for example one in the hall way one on the l. It is effectively three single gang intermediate switches on one face plate.
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. 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. Always ensure that the mains supply has been suitably isolated before commencing installation.
In order to control this lighting point from the three positions the intermediate switch is connected together with two other 2 way switches.
It can be used in lighting a room or hall having 3 entrances it can. It can be used in lighting a room or hall having 3 entrances it can.
