Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite operation type electric component in which a rotary electric component such as a rotary switch or a rotary volume is incorporated outside a multidirectional switch, and more particularly to an illumination structure thereof.

[0002]

2. Description of the Related Art Conventionally, as disclosed in Japanese Utility Model Laid-Open Publication No. 57-80029, a composite in which four push-button switches arranged inside and a rotary switch arranged outside are integrally incorporated. Operational electrical components are known.
In this composite operation type electric component, the knob of the push button switch is illuminated by a light source arranged in the center of each push button switch, and a position detection in four directions according to the push operation of each push button switch, and Continuous signal detection according to the rotation operation of the switch can be performed.

[0003]

However, in the above-mentioned conventional composite operation type electric component, since four independent push-button switches are used as the inner electric components, the operability of the push-button switches is poor, and the overall operation is poor. There are disadvantages such as an increase in size. Therefore, a composite operation type electric component in which a multidirectional switch is used as the inner electric component and a rotary electric component is incorporated outside the multidirectional switch is considered. According to such a composite operation type electric component, not only can several kinds of switching signals be output in accordance with the tilting operation of the operation lever provided in the multi-directional switch, but also another different signal can be output in accordance with the push operation of the operation lever. A switching signal can be output, and operability can be improved and size can be reduced.

However, as is well known, the multi-directional switch has a tiltable operating lever at the center thereof. Therefore, when illuminating a knob attached to the upper end of the operating lever, a light source is located at the center of the multi-directional switch. Even if the space for arranging the light source is secured just below the knob, the operating ring of the rotary electric component must be rotatably arranged outside the light source. The problem that supply becomes difficult arises.

[0005]

SUMMARY OF THE INVENTION According to the present invention, first and second conductive plates each having an LED connected thereto are fixed to an operation ring of a rotary electric component, and sliding plates provided on these conductive plates in opposite directions are provided. The child is sandwiched between a pair of power supply plates. With this configuration, the LED that rotates integrally with the operation ring
Since power is supplied from the power supply plate via the slider and the conductive plate, a knob or the like attached to the operation lever of the multidirectional switch can be illuminated.

As the rotary electric component, an electric component such as a rotary switch or a rotary volume in which an operation ring rotates can be used, and the operation ring may be a finite rotation within 360 degrees or an infinite rotation of 360 degrees or more.

When a cutout is formed in a part of the operation ring so that the first and second conductive plates are inserted, both the conductive plates can be easily integrated with the operation ring. In addition, the size of the LED and the power supply plate can be reduced by distributing the LED inside and outside the operation ring.

A driving body 10 made of a synthetic resin is fitted to the outside of the operation lever 3, and the operation lever 3 and the driving body 10 are spline-coupled so that they can relatively move only in the axial direction. A second movable contact plate 11 is fixed to the driving body 10, and the second movable contact plate 11 is pressed against the lower surface of the lid 2 by the biasing force of a conductive coil spring 12.

The switch 3 rotates around the fulcrum, and only one of the eight normally-closed switches S2 is turned on while the rest are turned off. When the operating lever 3 is further tilted in the same direction, the lower end of the operating lever 3 presses the first movable contact plate 7 via the cushioning rubber 9 and the pressing piece 8, and the first movable contact plate 7 is fixed to the first fixed position. When the contact 5 comes into contact, the normally open switch S1 is turned on. as a result,
Since a conduction path is formed between the normally open switch S1 and one normally closed switch S2, for example, if an output signal between the first fixed contact 5 and each second fixed contact 13 is taken into the microcomputer, The tilt direction of the operation lever 3 can be determined based on whether an ON signal is output from the second fixed contact 13. On the other hand, when the operating lever 3 is pushed in the neutral position in FIG. 1, the driving body 10 and the second movable contact plate 11 do not move, and only the operating lever 3 moves directly below and moves through the cushion rubber 9 and the pressing piece 8. To press the first movable contact plate 7. When the first movable contact plate 7 comes into contact with the first fixed contact 5, a conduction path is formed between the normally open switch S1 and all the normally closed switches S2. The microcomputer can detect the push operation of the operation lever 3 based on the eight ON signals from the contacts 13.
