Question: Why is a 3-way switch so named when it only operates from two locations?


Dave’s Reply:
Thanks for your electrical question Bill.
Three Way Switches

Bill, the original title:  “Three Way Switch”  has to do with the original identification of how the wiring was brought into the configuration when 3-way switches were first developed. Due to creative minds and new wiring techniques we now know that there are several methods to wire two 3-way switches ans still accomplish the same result.
