US 2012/0222942 A1 · ELECTRONIC DEVICE WITH SWITCHES TO SELECTIVELY CONTROL SAFE ACCESS

Abstract

An exemplary electronic device includes a casing, a first switch, a second switch and a switch control unit. The casing includes a side plate and a top plate detachably connected with a top end of the side plate. The first switch is turned on when the top plate is connected to the side plate and turned off when the top plate is detached from the side plate. The switch control unit includes a sliding member mounted at one side of the second switch. The sliding member includes a pressing plate. The sliding member is moveable relative to the side plate between a first state in which the pressing plate aligned with and pressing the second switch to turn on the second switch and a second state in which the pressing plate is staggered with the second switch to turn off the second switch.
