Abstract: A switch assembly comprises first and second tact switches located on a printed circuit board (PCB) at a predetermined interval, a shuttle body having a pair of tension ribs, including a first tension rib and a second tension rib located in parallel with each other, to turn on/off the first and the second tact switches, and a knob holding shaft provided between the first and the second tension ribs, a manipulation knob connected to the knob holding shaft of the shuttle body, rotating between a position where the manipulation knob presses one of the first and the second tension ribs to operate the corresponding tact switch and a position where the manipulation knob releases the tension rib, and a spring member connected with the knob holding shaft of the shuttle body elastically pressing the manipulation knob to the releasing position.

Abstract: A door interlock unit to be used with a disk recording/reproducing apparatus having a disk tray and a door through which the disk tray moves in and out of the disk recording/reproducing apparatus, the door interlock unit including a restricting member to restrict the door from being opened in response to the disk tray being positioned inside the disk recording/reproducing apparatus, wherein the restricting member is engaged by the disk tray entering the disk recording/reproducing apparatus; and/or a restricting member to restrict the disk tray from moving toward a disk loading position in the disk recording/reproducing apparatus in response to the door being in an open position; wherein the restricting member is coupled to the door so as to be engaged and disengaged by the door opening and closing, respectively.
