Electronic device

An electronic device, comprising:

• a housing having a first opening and one or more second openings, the housing being configured to accommodate an electronic component and a discharge resistor for discharging the electronic component;
• a discharge switch accommodated in the housing, the discharge switch including
• a pair of terminals, one of the pair of terminals being electrically connected to the electronic component, the other of the pair of terminals being electrically connected to the discharge resistor, and
• a movable member made of a conductor and positioned in a conductive position where the movable member is in contact with both of the pair of terminals or in a non-conductive position where the movable member is spaced apart from at least one of the pair of terminals;
• a first cover being openable and closable and configured to cover the first opening;
• a displacement limiting member that allows the movable member to be positioned in the conductive position when the first cover is opened and maintains the movable member in the non-conductive position when the first cover is closed,
• one or more second covers being openable and closable and configured to cover the one or more second openings,
• one or more locking mechanisms to lock the one or more second covers and allow a key to be removable only when the one or more second covers are locked, and
• a key holder disposed inside the housing and configured to hold the key, wherein
• the key holder includes
• a holding mechanism positioned at either an unlocked position that allows insertion and removal of the key or a locked position that suppresses removal of the key inserted therein, and
• an opening-closing limiting mechanism that suppresses closing of the first cover when the holding mechanism is position in the unlocked position and allows the first cover to be closed when the holding mechanism is positioned in the locked position, and
• when the movable member of the discharge switch is positioned in the conductive position, the electronic component is electrically connected to the discharge resistor, and when the movable member of the discharge switch is positioned in the non-conductive position, the electronic component is electrically disconnected from the discharge resistor.
