1. A switch for driving a drive unit, the switch comprising:
a movable unit movable in response to an operation, the drive unit being drivable in response to movement of the movable unit;
an operation-linked unit movable in response to the movement of the movable unit receiving the operation; and
an operation follower unit spaced from the operation-linked unit, the operation follower unit being movable in response to movement of the operation-linked unit with a magnetic force between the operation follower unit and the operation-linked unit, the magnetic force causing the operation follower unit and the operation-linked unit to attract each other, wherein
at least one of the operation-linked unit or the operation follower unit is magnetic, and
the drive unit is drivable in response to movement of the operation follower unit, which causes a change in a capacitance that determines an output of the drive unit.
