4 way switch symbol. 4 way switch symbol r stencils library. This page is just intended as an aid in case you want to view the sequence of images more slowly. If you understand how to wire a 3 way switch youll have no issues with a 4 way switch. Dimmer switch the dimmer switch symbol may refer to a variety of dimming type light switches which are used to control dimmable light fixtures commonly found in areas such as living rooms and bed rooms. Most valve symbols have three parts see figure 2a below. Use it for drawing electrical design floor and building plans devices and equipment layouts in the conceptdraw pro diagramming and vector drawing software.
Pneumatic circuit valve symbols. You can have an indefinite number of 4 way switches in a circuit. As you will see most 4 way switch wiring is placed between the wiring of two 3 way switches therefore a 4way switch is installed with two 3way switches. Here is a brief breakdown of how to read a symbol. To illustrate the 4 way switch wiring switch boxes and fixture boxes are not shown but are obviously required for every application. For a discussion of how to wire such circuits see 3 way and 4 way light switches.
As above with the three way switch but here three switches will control typically a light or group of lights. They all must be between the two 3 way switches. It is important to understand how these switches are wired before attempting to troubleshoot or replace. The center switch is 4 way switch while the outer two switches are 3 way. The vector stencils library switches contains 25 symbols of electrical switches. The actuators are the mechanisms which cause the valve to shift from one position to another.
That page discusses proper wire colors and several ways to wire a multiswitch circuit. My 4 way switches dont work. 4 way switch configurations are used to control lights with three or more switchesa 3 way switch is used on each end with one or more 4 way switches in between the two 3 way switchesthey do not have an onoff position like single pole switches.
