The Clapper
Summary

Sound activated electrical switch

The Clapper is a sound-activated electrical switch, 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!".

The Clapper plugs into a U.S.-type electrical outlet, and allows control of up to two devices plugged into the Clapper. An upgraded model, known as the Clapper Plus, includes a remote control function in addition to the original sound-based activation.

Although meant to activate by clapping, The Clapper can inadvertently be triggered by other noises like dogs barking for example.
