In North America, this rarely used term describes a basic single-pole, single-throw switch with simple on and off positions. In British and Commonwealth systems, it refers to a single-pole, double-throw switch used in pairs to control a light from two different locations. The regional naming difference frequently causes miscommunication on international jobs.
