The Clapper is a sound-activated electrical switch, [1] sold since 1984 by San Francisco, California based Joseph Enterprises, Inc. Joseph Pedott marketed the clapper with the slogan "Clap On! Clap Off! The Clapper!". [2]
The Clapper plugs into a U.S.-type electrical outlet, and allows control of up to two devices plugged into the Clapper. [3] An upgraded model, known as the Clapper Plus, includes a remote control function in addition to the original sound-based activation. [4]
Although meant to activate by clapping, The Clapper can inadvertently be triggered by other noises. [5]
The Clapper was invented by Carlile R. Stevens and Dale E. Reamer, and issued U.S. Patent #5493618, which was published on 20 February 1996. [6]
