ABSTRACT:
A lever switch apparatus has a lever operable in a plurality of directions, which, when operating the lever in a certain direction, prevents against erroneous operation of a movable board by rendering the movable board immovable in an irrelevant direction of lever operation. The lever switch apparatus has a lever 2 and a movable board 3A. The lever 2 is swingable in a first direction and a second direction about a first axis 21 and a second axis 22, and has an engager 23 on a tip side thereof. The movable board 3A is swingable in a third direction about a third axis 31A, and has an elongate hole 32A extending in the second direction and a contact piece 33A. The engager 23 is engaged with a wall surface 34A of the elongate hole 32A. The elongate hole 32A is formed in a curved form corresponding to a swing path of the engager 23 to prevent erroneous operation of the movable board 3A during movement of the lever 2 in certain directions.
