Most switches are either layer 4 or layer 7, so you can think of a switch as a layer that is used to control a certain level of electrical current. This is a pretty basic explanation to give you an idea of what a switch is, but I would like to go into more detail about how switches actually work in more details. I hope that was helpful.
You can make a switch either switch the current flow or toggles it on and off. For example, if you have a switch that controls the current flow then it is layer 4. If you have a switch that controls the current flow toggles it then it is layer 7. When you use a layer 7 switch you are basically telling the controller that the current doesn’t need to be flowing in order to be seen.
It’s often called a “Switch” or a “Layer” switch because it basically is a layer of functionality, but I would like to go into more detail. A switch controls a single current flow. That means that you can either control the flow of current in the direction you want, or you can control it toggles it on and off.
One of the first things you learn about switches is that you can only control current flow that flows in the direction you select. It is layer 7 because its the most powerful switch. Layer 7 switches actually have two purposes: They control the flow of current and they are the only switches with 2 different functions.
Layer 7 switches are sometimes called “double-sided” switches because you can control the direction of current flow in both directions. Layer 6 switches, in contrast, have one function. It controls the direction of current flow. It is layer 4 because of how many layers are assigned to each switch.
Layer 5 switches, in contrast, have only one function. A layer 5 switch is just a switch with two functions. Layer 4 switches, however, are also called dual-sided switches because you can control the direction of current flow both directions. Layer 3 switches, on the other hand, are also called single-sided switches because you can only control the direction of current flow.
The switches that function for layer 4 are known as “push-on” switches. They control current flow and provide a way to tell an electrical device from a light switch. The switches that function for layer 5 are known as “pull-off” switches. They are used for two different things: to turn on and off the light and to turn on and off the switch.
For example, a switch that is known as a push-on switch is used to turn on the light, but a switch that uses a pull-off action is used to turn off the light.
To turn off a light switch, you pull the knob on the switch to the right. Then you turn the knob on the switch to the left. When you pull the right knob, the light turns off. When you turn the left knob, the light turns on. The switch used for this is known as the “pull-off switch”.
This is a good way to avoid accidentally turning the lights off. For example, you have a light switch next to a lightbulb. If you accidentally pull the knob on the switch to the left of the lightbulb, the lightbulb will turn off. If you accidentally pull the knob to the right of the lightbulb, the lightbulb will turn off.
