The diagram shows the common method of wiring an intermediate switch into a two way light switch circuit. To wire a three way lighting circuit you will need 2 two way switches and an intermediate switch.
Tutorial 3 Way Switches And 4 Way Switches
Intermediate light switch wiring. 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. If replacing an existing switch note the location of the terminals and the colour and position of cable connections. All three switches are connected together by a three core and earth control cable. Notice that the wire connected to the com terminals is looped straight through the intermediate switch using a cable connector. 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. The white wires get spliced through.
Wiring a single pole light switch here a single pole switch controls the power to a light fixture. The circuit consists of a two way switch at each end top and bottom switches in fig 2 and an intermediate switch in the middle. It is effectively two single gang intermediate switches on one face plate. The source is at the switch and 2 wire cable runs from there to the light. 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. In a previous video i showed how a two way.
The source hot wire is connected to a switch terminal and the other terminal is connected to the black cable wire. An intermediate switch is used if more than two switches are required to control a two way lighting circuit. Double gang switch face plate. It is effectively two single gang intermediate switches on one face plate. This video also shows how an intermediate switch works. Double gang switch face plate.
In some countries the four way is called an intermediate switch. Staircase wiring connection using 2 two way switches and intermediate switch controlling of lamp from 6 six places by intermediate switch. Staircase wiring using intermediate switch below is a given schematic circuit to control a light point from three different places by using two 2 way switches and intermediate switch in the middle of stairs. It should be fitted between the first and the last switches on the circuit.
