Why does my light switch have 3 wires?

How do I turn a 3-way switch into a single pole?
To convert a 3-way switch to single pole, one of the traveler wires is removed from the switch. In order for a 3-way switch to function as a single pole, the wires need to be connected to the common and one of the traveler terminals. It will not work if the wires are connected to the two traveler terminals.
