Electronic device with a switch to prevent over-discharging of device battery

An electronic device comprising an over-discharge preventing apparatus, the electronic device comprising:

• a housing comprising a first opening and a second opening;
• a first electronic component arranged inside the housing;
• a second electronic component electrically connected with the first electronic component;
• a switch configured to electrically connect the first electronic component with the second electronic component or block an electrical connection between the first electronic component and the second electronic component, by an external force exerted by a pin inserted through the first opening;
• a tray inserted into or drawn out of the housing through the second opening;
• and
• a push bar configured to receive the external force from the pin inserted into the first opening and deliver a force to press the switch,
• wherein the switch comprises:
• a first terminal electrically connected with the first electronic component,
• a second terminal electrically connected with the second electronic component, and
• a movable member blocking an electrical connection between the first electronic component and the second electronic component by being inserted between the first terminal and the second terminal, or electrically connecting the first electronic component with the second electronic component by moving away from between the first terminal and the second terminal.
