Switches don’t require any fancy equations to evaluate. All they do is select between an open circuit and a short circuit. Simple. But how could we live without buttons and switches!?
What is a Toggle Switch?
A toggle switch is a device which controls the open or closed state of an electric circuit. Toggle simply means to go “back and for” or “to and fro”.
The switch allows control over current flow in a circuit. Switches are critical components in any circuit which require user interaction or control.
A switch can only exist in one of two states: open or closed. In the off state, a switch looks like an open gap in the circuit. This open circuit state prevents current flow.
In the on state, a switch acts just like a piece of perfectly-conducting wire. A short. This closes the circuit, turning the system “on” and allowing current to flow unimpeded through the rest of the system.

There are tons and tons of switches out there: toggle, rotary, DIP, push-button, rocker, membrane, … the list just goes on and on. Each of those switch types has a set of unique characteristics to differentiate it from others. Characteristics like what action flips the switch, or how many circuits the switch can control. Next up, we’ll go over some of the more basic switch characteristics.
In order to change from one state to another, a switch must be actuated. That is, some sort of physical action must be performed to “flip” the switch’s state. The actuation-method of a switch is one of its more defining characteristics.
