The Clapper
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 like dogs barking for example.[5]
