ABSTRACT:
An apparatus for sensing a button-pressed state in a mobile device comprising a switch unit formed by combining rotary switches in a switch unit and a controller connected to the rotary switches within the switch unit, for sensing a switching operation according to a connected state between contact points of the rotary switches. The controller senses the connected state between the contact points of the rotary switches through an input/output port, and recognizes a rotating direction, an operation order, and a number of rotations of the rotary switches on the basis of the connected state. The controller determines if the switching operation is intended or not so that a desired operation corresponding to the switching operation is performed only if the operation is intended to thereby save battery power by minimizing performing unintended operation.
