Switching device
View Patent ↗At a position which is overlapped to a space defined between a plane of projection of a first manipulating member with respect to a PCB and a plane of projection of a second manipulating member with respect to the PCB, first and second switches are arranged. First and second portions to be manipulated of the first switch are projected from a switch casing such that the first and second portions to be manipulated of the first switch are pushed and manipulated by projections at back sides of pushing surfaces of the first and second manipulating members, and first and second portions to be manipulated of the second switch are projected from the switch casing such that the first and second portions to be manipulated of the second switch are pushed and manipulated by other projections at back sides of other pushing surfaces of the first and second manipulating members.
1. A switching device comprising:
a first manipulating member rotatably mounted and having a first pushing surface on a top thereof at a first end in a direction perpendicular to a rotational axis of the first manipulating member and a first pushing portion provided behind the first pushing surface;
a second manipulating member positioned adjacent to the first manipulating member, rotatably mounted such that a rotational axis of the second manipulating member is parallel to the rotational axis of the first manipulating member and having a second pushing surface on a top thereof at a first end in a direction perpendicular to the rotational axis of the second manipulating member and a second pushing portion provided behind the second pushing surface; and
a first switch including a first switching portion having a first manipulated portion pressed by the first pushing portion, a first movable contact driven by the first manipulated portion, and a first fixed contact with which the first movable contact comes into contact; a second switching portion having a second manipulated portion pressed by the second pushing portion, a second movable contact driven by the second manipulated portion, and a second fixed contact with which the second movable contact comes into contact; and
a first casing accommodating the first and second movable contacts,
wherein the first casing is overlapped by the first and second manipulating members when viewed from above, and the first and second manipulated portions project from the first casing and are in contact with the first and second pushing portions, respectively
wherein the first and second manipulating members have third and fourth pushing surfaces respectively, at a second end in the direction perpendicular to the rotational axes and third and fourth pushing portions provided behind the third and fourth pushing surfaces respectively;
a second switch is positioned adjacent to the first switch along the direction perpendicular to the rotational axis of the first manipulating member, the second switch includes a third switching portion having a third manipulated portion pressed by the third pushing portion, a third movable contact driven by the third manipulated portion, and a third fixed contact with which the third movable contact comes into contact; a fourth switching portion having a fourth manipulated portion pressed by the fourth pushing portion, a fourth movable contact driven by the fourth manipulated portion, and a fourth fixed contact with which the fourth movable contact comes into contact; and
a second casing accommodating the third and fourth movable contacts,
wherein the second casing is overlapped by the first and second manipulating members when viewed from above, and the third and fourth manipulated portions project from the second casing and are in contact with the third and fourth pushing portions respectively.
2. A switching device according to claim 1 ,
wherein the first and second portions to be manipulated are independently operable.
3. A switching device according to claim 1 ,
wherein the switching device comprises a light transmitter having transparency which is formed on at least one of the first and second manipulating members, an illumination element which illuminates the light transmitter from a back side of the manipulating member on which the light transmitter is formed, and a terminal which holds the illumination element at a given position on the back side of the manipulating member and electrically connects the illumination element to a circuit on the substrate.
