An electronic device including a housing, a detachable member, and a latch is provided. The detachable member is assembled to the housing and has a position limiting unit with a guiding surface and a limiting surface. The latch is movably disposed in the housing between a first and a second positions for locking or unlocking to the detachable member. The latch has an elastic unit, and the position limiting unit is on a moving path of the latch. When the latch moves from a first position toward a second position, the elastic unit moves along the guiding surface to the limiting surface and is position-limited at the second position.
