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.

Abstract: A power supply device is provided. The power supply device includes a first switch element for selectively providing an alternating current (AC) power source to an actuation device, a second switch element for selectively providing the AC power source to the first switch element, a detection circuit for confirming whether or not the first switch element is in a full turn-on state, by comparing an input power source and an output power source of the first switch element, a sensor for sensing the size of the AC power source, and a controller for selectively controlling the operation of the second switch element on the basis of the sensed size of the AC power source and the confirmed full turn-on state.

Abstract: A power supply device is provided. The power supply device includes a rectifier circuit for rectifying an inputted alternating current power supply, a capacitor circuit comprising a first and second capacitor which are connected in series, and smoothing the alternating current power supply rectified in the rectifier circuit, an inverter for converting the output power of the capacitor circuit to a preset power and outputting same, a switch for selectively connecting a middle node of the first capacitor and the second capacitor and an end of the alternating current power, a sensor for detecting a size of the alternating current power, and a controller which confirms a power mode of the alternating current power on the basis of an output value of the sensor, and which controls the switch so that the capacitor circuit multiplies and amplifies the selectively rectified alternating current power based on the confirmed power mode.
