    Abstract: An electronic device includes one or more processors, a memory storing instructions, and a user interface including at least one touch button, a capacitor coupled with the at least one touch button, and a switch configured to charge the capacitor and to discharge the capacitor. The instructions, when executed by the one or more processors individually or collectively, cause the electronic device to spread an operating frequency into a plurality of spread frequencies within a frequency range, determine, based on the plurality of spread frequencies, whether to at least one of charge the capacitor or discharge the capacitor by controlling the switch to at least one of turn on or turn off, measure a charging time of the capacitor, according to the controlling of the switch, and determine whether a touch input on the at least one touch button occurs, based on the measured charging time.

    Abstract: An electronic device including a main body having an opening, a door configured to open and close at least a part of the opening of the main body, and a door sensor, provided relative to an open-side edge of the door, to detect a touch input by using a capacitive method. The door sensor includes a touch key configured to receive the touch input, a sensor substrate comprising a conductive land; a connection member including a sensing surface contacting the touch key, and a connection surface contacting the conductive land so that the touch key is electrically connected with the conductive land through the connection member. Surfaces of the connection member along a thickness direction including the sensing surface and the connection surface and surfaces of the connection member along a longitudinal direction are electrically conductive surfaces. Surfaces of the connection member along a width direction are electrically non-conductive surfaces.
