Abstract
The signal input device according to an embodiment of the present inventive concept may have effects in that the number of buttons included in the signal input device can be reduced because different types of input signals can be generated depending on a direction of a laterally pushed manipulation force, and a configuration can be simplified, a production cost can be significantly reduced and two or more input signals can be simultaneously generated because a laterally pushed manipulation force can be detected although a separate pressure sensor is not provided.
