Abstract
An input key structure for an electronic device includes a first magnetic body, a circuit board and a second magnetic body. The circuit board has a switch. The second magnetic body rotates relative to the first magnetic body to selectively locate between an initial position parallel with the second magnetic body and a target position contacted with the switch. 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.

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.
An input key structure for an electronic device comprising:
- a first magnetic body;
- a second magnetic body parallel to the first magnetic body;
- and
- a circuit board with at least one switch facing the second magnetic body, the switch having an open state and a close state;
- wherein the second magnetic body is capable of rotating with respect to the first magnetic body to actuate the switch to selectively be in close state and the open state;
- wherein surfaces facing each other, of the first magnetic body and the second magnetic body, have different polarities, and a magnetic attractive force generated between the first magnetic body and the second magnetic body actuates the at least one switch to be in the open state from the close state;
- an input key;
- the input key and the circuit board being arranged at opposite sides of the second magnetic body;
- and
- 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.
