Abstract:
1. An input key structure for an electronic device comprising: a first magnetic body; a circuit board with a switch; and a second magnetic body rotatable with respect to the first magnetic body to selectively locate between an initial position parallel with the first magnetic body and a target position contacted with the switch; wherein the second magnetic body is structured to cooperate with the first magnetic body to generate a magnetic attractive force to automatically adjust the second magnetic body to the initial position when the second magnetic body is rotated away from its initial position to the target position; a shaft being insertable into the first magnetic body and the second magnetic body; wherein the shaft comprises a rod, a rim and a restricting portion arranged on opposite ends of the rod; the rim protrudes from a periphery of the rod, the restricting portion defines a slot, the input key structure further comprises a blocking member sleeved in the slot of the restricting portion, and the first magnetic body and the second magnetic body are sandwiched between the rim and the blocking member; and an input key; the input key and the circuit board being arranged at opposite sides of the second magnetic body.
