An illuminated switch comprising a four-way knob and a push knob, wherein the push knob has two legs which slide along a guide surface on an internal pusher member. Tilt activation of the four-way knob results in the push knob also being tilted. When the user has pushed the push knob while the push knob and the four-way knob are in a tilted position, the push knob in conjunction with the four-way knob linearly move backward in the pushed direction, whereby an internal switch and an external switch are operated. The push knob is illuminated by an internal LED by way of a through hole in the internal pusher member.

Illuminated dual action switch

When an operating knob (12) is moved in an XA direction, an XB direction which is opposite to the XA direction, or a Y direction which is perpendicular to the XA and XB directions, coupling bars (44), (45) provided in a holder (20) which moves together with the operating knob (12) travel over slanted edges of push plates (34), (35), causing a pusher (22) to move in the Y direction. In other words, the pusher (22) moves in the same direction regardless of the moving direction of the operating knob (12). When the pusher (22) moves, a projection (33) formed at a far end of an elastic element (32) provided on the pusher (22) presses against a tactility-producing wall (40), resulting in an increase in force required for moving the operating knob (12). When the projection (33) enters an inside space of the tactility-producing wall (40), a resisting force exerted by the projection (33) disappears, resulting in a decrease in operating force, but leaving an appropriate level of tactile feedback produced when the operating knob (12) is operated. This construction eliminates the need for providing a multidirectional switch with separate mechanisms for creating tactile feedback in individual operating directions of the multidirectional switch, and thereby simplifies its construction.
