Multi-directional switch
View Patent ↗A multi-directional switch contains a bearing 4 , an operating shaft 3 supported rockably by the bearing 4 , and a cam 15 c for giving a required feeling of operation to a rocking operation of the operating shaft 3 . In the cam 15 c , a spherical surface-shaped bottom portion 41 for holding the operating shaft 3 in a non-operation position, first inclined surfaces 42, 43, 44 and 45 formed in a radial shape at an outer circumference of the bottom portion 41 , and second inclined surfaces 46, 47, 48 and 49 formed in a radial shape at an outer circumference of the first inclined surfaces, are formed, and at the boundaries between the first inclined surfaces and the second inclined surfaces, swelled step portions 50, 51, 52 and 53 are formed, respectively.
1. A multi-directional switch, comprising:
a bearing;
an operating shaft rockably supported by the bearing; and
a cam for giving a required feeling of operation to an operation of the operating shaft,
wherein an actuator reciprocating along an axis of the operating shaft and an elastic member accelerating the actuator in one direction are provided in a tip portion of the operating shaft,
wherein, in the cam, a spherical surface-shaped bottom portion for holding the operating shaft in a non-operation position via the actuator, a plurality of first inclined surfaces formed in a radial shape at an outer circumference of the bottom portion, and a plurality of second inclined surfaces formed in a radial shape at an outer circumference of the first inclined surfaces and having an inclined angle less than those of the first inclined surfaces, are formed, and
wherein swelled step portions are provided at boundaries between the first inclined surfaces and the second inclined surfaces.
2. The multi-directional switch according to claim 1 , wherein the operating shaft is rockably and rotatably supported by the bearing.
