A switch is perhaps the most common type of electrical device, yet we know so little about it. Every room has at least one, and most of us still don’t know how to differentiate between the different types. This lack of being informed can sometimes lead to us wiring the wrong switch to a particular circuit. Truth is, most switches look the same on the outside, however it’s the way that their insides are designed that makes a switch appropriate for a certain type of job. According to this, there are four major types of electrical switches.
