Patent ID: 7592554

Claim:
A switch device comprising: an operational knob; a switch case attached to the operational knob; a shaft having an end portion provided with the operational knob and an intermediate portion accommodated and supported in the switch case so as to be rotatable around an axis of the shaft and swing in a rotational radial direction, the shaft enabling an operation of an inclination motion at a switch operational position where the operational knob is rotated from a neutral position; first and second stationary contact points located in the switch case; a first movable board supported in the switch case in such a manner as to be rotatable around an axis to the switch case and provided with a first movable element for switching a rotational direction contact position to the first stationary contact point in accordance with the rotation of the shaft; and a second movable board supported in the switch case in such a manner as to be movable in the plane direction and provided with a second movable element for switching a plane direction contact position to the second stationary contact point in accordance with the swing motion of the shaft, wherein one of the switch case and the shaft is provided with engagement projection portions at a plurality of locations in a rotational circumferential direction; and the other of the switch case and the shaft is provided with a guide portion including a limiting face for being engaged to the engagement projection portion at the neutral position of the operational knob to lock the swing motion of the shaft and a release recessed portion for releasing the engagement of the engagement projection portion at the switch operational position where the operational knob is rotated to allow the operation of the inclination motion by the operational knob in the plane direction by the swing motion of the shaft.
