A switch device includes a wiring board having a cutout provided therein, a land provided on an upper surface of the wiring board around the cutout, and a switch. The switch includes a lever, a switch contact activated upon the lever being moved in a predetermined direction, a case including a step portion protruding from a surface thereof and positioned in the cutout of the wiring board, and a terminal protruding from the case and mounted on the land of the wiring board. The switch device securely holds the switch on the wiring board with a simple structure, and allows the switch to be activated reliably.
1. A switch device comprising:
a wiring board having an upper surface, the wiring board having a cutout provided therein;
a land provided on the upper surface of the wiring board around the cutout; and
a switch including
a lever movable in a predetermined direction,
a switch contact activated upon the lever being moved in the predetermined direction, and
a case accommodating the switch contact, the case having a lower surface, the case including a step portion protruding from the lower surface and positioned in the cutout of the wiring board; and
a terminal protruding from the case, the terminal being mounted on the land of the wiring board;
wherein the case has a recess formed therein, the switch being accommodated in the recess; and
wherein the recess has a bottom which faces upward and which is located below the upper surface of the wiring board.
2. The switch device of claim 1 , wherein
the cutout contacts the step portion.
3. The switch device of claim 1 , wherein
the cutout is formed in an edge of the wiring board.
4. The switch device of claim 1 , wherein
the switch contact includes a fixed contact disposed on the bottom of the recess,
the terminal has a bent portion connected to the fixed contact, and
the terminal has a lower surface located below the upper surface of the wiring board.
5. The switch device of claim 1 , wherein the wiring board has a lower surface opposite the upper surface thereof, and the step portion is located above the lower surface of the wiring board.
6. The switch device of claim 1 , wherein
the cutout is provided in an anterior edge of the wiring board and has a first side edge, a second side edge facing the first side edge, and a back edge located at a back of the cutout, the first side edge being connected to the anterior edge of the wiring board, the second side edge being connected to the anterior edge of the wiring board,
the lever is movable in the predetermined direction and in a direction opposite to the predetermined direction, and
the first side edge of the cutout faces in the predetermined direction, and the second side edge faces in the direction opposite to the predetermined direction.
7. The switch device of claim 6 , wherein
the cutout is formed in an edge of the wiring board.
8. The switch device of claim 6 , wherein
the first side edge of the cutout contacts the step portion.
9. The switch device of claim 8 , wherein
the second side edge of the cutout contacts the step portion.
10. The switch device of claim 1 , wherein
the cutout has an edge facing the step portion of the case in a direction opposite said predetermined direction so that, upon movement of the lever in said predetermined direction, the edge of the cutout is contacted by the step portion so as to limit any movement of the case in said predetermined direction caused by a force that moves the lever in said predetermined direction.
11. The switch device of claim 10 , wherein
the cutout is formed in an edge of the wiring board.
12. The switch device of claim 1 , wherein
the lever is further movable in a second direction opposite said predetermined direction; and
the cutout has first and second side edges facing the step portion of the case in said second direction and said predetermined direction, respectively, so that, upon movement of the lever in said predetermined direction, the first edge of the cutout is contacted by the step portion so as to limit any movement of the case in said predetermined direction caused by a force that moves the lever in said predetermined direction, and so that, upon movement of the lever in said second direction, the second edge of the cutout is contacted by the step portion so as to limit any movement of the case in said second direction caused by a force that moves the lever in said second direction.
13. The switch device of claim 12 , wherein
the cutout is formed in an edge of the wiring board.
