Switch apparatus
View Patent ↗A switch apparatus, including: a substantially box-like case; a cylinder section; a lever; a substantially cylindrical columnar support; an engagement convex section; an engagement concave section; and a press-in section. The cylinder section is provided at a substantial center of the case and has at an inner circumference thereof a reception section. The lever is attached to the case and is pivoted and operated to provide an electric connection of switch contacts provided in the case. The columnar support is inserted to the cylinder section and has one end that is abutted with the reception section. The engagement convex section is provided at one of the reception section and the columnar support and the engagement concave section is provided at the other. The press-in section is provided at one of the engagement convex section or the engagement concave section. The engagement convex section is pressed-in to and engaged with the engagement concave section via the press-in section. The structure as described above provides a switch apparatus that has a simple configuration, that reduces the backlash when the lever is operated, and that can be operated in a favorable manner.
1. A switch apparatus, comprising:
a substantially box-like case:
a cylinder section that is provided at a substantially center of the case and that has at an inner circumference thereof a reception section;
a lever that is attached to the case and that is pivoted and operated to provide an electric connection of switch contacts provided in the case;
a substantially cylindrical columnar support that is inserted to the cylinder section and that has one end abutted with the reception section;
an engagement convex section provided at one of the reception section and the columnar support;
an engagement concave section provided at the other of the reception section and the columnar support; and
a press-in section provided at one of the engagement convex section and the engagement concave section,
wherein the engagement convex section is pressed-in to and engaged with the engagement concave section via the press-in section.
2. The switch apparatus according to claim 1 ,
wherein the press-in section is elastically deformable.
3. The switch apparatus according to claim 1 ,
wherein the press-in section has a cross-sectional area that is gradually increased against an engagement direction in which the engagement convex section is engaged with the engagement concave section.
4. The switch apparatus according to claim 3 ,
wherein the press-in section has a triangular pyramid shape.
5. The switch apparatus according to claim 3 ,
wherein the press-in section has a columnar rib-like shape.
6. The switch apparatus according to claim 2 ,
wherein the press-in section has a V-like shape.
