Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a slide switch used in a control section of an audio device installed on board an airplane, train, or the like.

BACKGROUND OF THE INVENTION In general, slide switches used in audio equipment are
A commercially available single switch completed product having the configuration shown in the figure is used.

An example of a conventional slideable bench will be described below with reference to the drawings.

FIG. 6 shows an example of the configuration of a conventional slide switch. In the figure, 1 is a slide button, 2 is a cabinet, and has a window hole 3. Reference numeral 4 denotes a switch case, which has a click hole 5 and a terminal fixing plate holding claw 6.

A terminal fixing plate 7 holds a fixed terminal 8.

9 is a movable terminal. 10 is a slider which can hold the click spring 11 and the steel ball 12 in the spring holding hole 13, while the movable terminal 9 is held in the movable terminal holding hole 14.

The operation of the slide switch configured as described above will be explained below. This slide switch is already assembled into one piece and is commercially available. The switch case 4 holds the terminal fixing plate 7 with the terminal fixing plate holding claws 6 to form one housing, and the slider 1o is housed in the housing. Fixed terminals 8 are fixed to the terminal fixing plate 7, and a movable terminal 9 slides between the fixed terminals 8. This movable terminal 9
is held in a movable terminal holding hole 14 provided in the slider 10 and moves according to the movement of the slider 10. The slider 1o is provided with a spring holding hole 13, into which a click spring 11 and a steel ball 12 fit. is generated.

A commercially available switch having the above configuration is passed through the window hole 3 of the cabinet 2, and a slide button is fitted to complete the slide switch.

Problems to be Solved by the Invention However, such a slide switch configuration has a large number of parts and a complicated structure, which not only increases cost, but also increases weight, making it difficult to operate like an airplane. This was a big problem for devices that wanted to be even one gram lighter.

In view of the above problems, the present invention provides a slide switch that is light in weight and has a simple structure.

Means for Solving the Problems In order to solve the above problems, the slide switch of the present invention has the following features:
A brush plate and a click plate are combined with a slide button across the cabinet, and a coil spring positions the slide button, and the click plate and a convex part provided on the inner wall of the cabinet create a sense of moderation. It is something that

Function: The slide switch of the present invention eliminates the need for a terminal fixing plate by fixing the brush directly to the slide button, and also eliminates the need for a switch case and slider by configuring the slide button and brush plate with a cabinet in between. I don't. The click mechanism used to have a steel ball and click spring sandwiched between the slider and the switch case, but now it has a brush plate and click plate fixed to the slider button, and in addition, a steel ball, click spring, and switch case. Since the click hole is configured with a coil spring and a convex portion provided on the inner wall of the cabinet, the configuration becomes simple and the weight can be reduced.

EXAMPLE Hereinafter, a slide switch according to an example of the present invention will be described with reference to the drawings.

In Figures 1 to 6, 21 is a slide button;
2 is a cabinet, 23 is a window hole into which the slide button 21 fits, 24 is a rib that adjusts the position of the slide button 21, 25 is a projection for generating a click, 26 is a coil spring, 27 is a click plate, and 28 is a brush. 29 is a printed wiring board, and 30 is a conductive agent.

A click board 27 and a plan base 28 are fixed by sandwiching a window hole 23 of a cabinet 22 between a slide button 21 and a window hole 23 of a cabinet 22. At this time, the rib 31 serves to position the slide button 21 so that it does not wobble in the button insertion direction. In this state, the size of the window hole 23 is set so that the slide button 21 can slide within the window hole 23. The spring part of the click plate 2 is always in pressure contact with the inner wall of the cabinet 22, and by sliding the slide button 21, the click protrusion 25 provided on the inner wall of the cabinet 22 is moved onto or away from the spring, and the slide button 1 is operated. It is possible to give a click feeling to the image.

Further, a coil spring 26 is fixed to the inner wall of the cabinet 22 for the purpose of positioning the slide button 21 in the sliding direction. This coil spring 26 supports the slide button 21 from two directions so that the slide button 21 is always in a constant position.
Press the walls on both sides.

It also has the role of applying force to return the slide button 21 to its original position when it is moved. Along with this sliding movement, the brush plate 28 also moves, and the conductive agent 30 on the printed wiring board 29
slide on top.

As described above, according to this embodiment, the structure is simple, the number of parts is small, and it is possible to reduce costs and weight.

Effects of the Invention As described above, the present invention directly fixes the slide button and the plastic sheet metal cabinet by sandwiching it, thereby reducing the number of parts and simplifying the configuration, resulting in cost and weight reductions. It is possible to plan.
