How a typical single-pole wall switch is wired depends on whether it is located in the middle of a circuit or at the end. It’s a little complicated and has to do with whether or not there are multiple switches controlling a single fixture, usually a light. If the switch is in the middle, two 3-wire cables will be in the switch box: one from the power source and the other heading out to the load. If it is on the end, only one cable with three or four wires comes into the box.

If you are making a one-for-one switch replacement, it is usually safe to assume that the old switch was wired correctly, and simply get a new switch that is configured like the old one and hook it up the same way.
