Where 0 represents the off condition and 1 represents the on condition. At the other end you connect the other 3 way switch with either the line or the load.
How To Wire Three Way Switches Part 2
Intermediate switch connection diagram. This is an updated version of the first arrangement. 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. How to connect 2 way switch wiring using three wire control. Staircase wiring connection using 2 two way switches and intermediate switch controlling of lamp from 6 six places by intermediate switch. If replacing an existing switch note the location of the terminals and the colour and position of cable connections. The intermediate switch includes four terminals where these terminals will change the flow of current from circuit to circuit.
Intermediate switches can be used for 1 and 2 way switching. An intermediate switch connection and operation. The diagram shows the common method of wiring an intermediate switch into a two way light switch circuit. This page shows it wired in the old cable colours if your house has the new colours you want to go here. This method is commonly used now days as it is efficient than the two wire control system. All three switches are connected together by a three core and earth control cable.
The red and black are used for hot and the white neutral wire at the switch box allows for powering a timer remote control or other programmable switch. Intermediate switch wiringwiring diagram. Here we have a 3 way switching lighting circuit sometimes called two way switching with intermediate. The main function of this switch is to turn on turn off the electric supply in two ways. This allows a single light to be turned on or off from any of the switches. It also called three way switches.
This is the new method to make a 2 way switching connection as it is slightly different from the two wire control method. Sometimes the switch wiring connection diagram is printed on the inside of the 4 way switch packaging box see example below. Because the electrical code as of the 2011 nec update requires a neutral wire in most new switch boxes a 3 wire cable runs between the light and switch. In fig 5 a lamp is controlled from six different places by using two 2 way switches and four intermediate switches. Follow the switch manufacturers instructions and wiring diagram as the connections on the switch vary by manufacturer. Notice that the wire connected to the com terminals is looped straight through the intermediate switch using a cable connector.
