Abstract: A switch device for a motorcycle or the like having a handle grip fitted to one end of a handle bar, a swtich case arranged on a inside portion of an end of the handle grip, and a switch knob element mounted on a mounting surface of the switch case. This conbination is characterized in that the switch device comprises support elements operable to position the switch knob element with a center line thereof being inclined relative to a line extending perpendicular to a longitudinal axis of the handle bar. Further, the switch knob element includes multiple operating locations operable to effect deverse operating conditions in response to depression by an operator's hand digit tip, with these multiple operating locations being disposed generally along an arcuate path traversed by the operator's hand digit tip while the operator is hand-gripping the handle grip.
