How do you hook up a 4 way switch, install a three-way switch
If not marked, the common terminal may be color-coded black or brass.
If the user is unable to perform electrical work themselves, a qualified electrician should be consulted. Note connections of the ground wire. Most codes dictate that all wire connections must be placed inside a switch, receptacle or junction box.
The diagram below will give you a good understanding how this circuit is wired.
A Completely Different Approach: Radio Remote Control
You installed the wiring, covered it all with dry-wall, and have now discovered that you did not pull 3-conductor cable everywhere you should have. This circuit also shows rough-in boxes, wire nuts, and proper color code. White or neutral wire taped with black electrician's tape is used as black power wire to make connections throughout.
So top left red connects to bottom right black and when toggled top left red connects to top right red.

A 4-way dimmer diagram is included as well as an arrangement to control the lights from four different points.
The usual practice in home construction is to use 3-way switches. Three-wire cable runs between all the switches and the traveler wires are connected between the two 3-ways and the 4-way.
In such cases, it is convenient and permissable to bring volts to a switch via a white wire. Click Image or here to enlarge Diagram Option 3.
