The clapper contains a microphone and a trigger circuit that responds to sharp, loud noises such as your hands clapping. Chances are good that they have included a circuit which limits the range of frequencies in which it'll respond, helping to tune it to match the audio frequency of the clapping sound.
The trigger circuit has several possible designs, especially in designing the portion that controls the AC for the lights, TV, etc. But rest assured, the manufacturer will make it the most dependable and least expensive way possible.
It's relatively easy to design and build yourself, but mass production just makes it more convenient and in most cases, cheaper to just go ahead and buy one.

What is the function of clapper box in shaper?
The shaping machine usually cuts on the forward stroke and does not on the backward stroke. So its not required for the tool to be in contact with the work piece when its on the backward stroke. This is ensured by the Clapper box, a device which is hinged to the ram. The lifting of the cutting tool by the clapper box ensures longer tool life and also accidental scratch or other machining defects on the work piece/final product.
