Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an operating mechanism for a push button switch that can be easily installed in an accurate position.

[Prior Art] A push button switch operating mechanism on the operation panel of an electronic musical instrument, in which a plurality of push button switches whose contacts open and close each time the operating knob protruding from the switch body is pressed down, is arranged in advance on a board in rows. Arrange them in a shape. The board is mounted facing the panel, the switch operating knob is slightly protruded from a hole in the panel surface, and a player or the like presses down the operating knob. In order to visually display the open/close status of the switch contacts on the board from both sides of the panel,
An indicator lamp, such as a red light emitting diode, is placed in series with each switch contact. By looking at the display on the light emitting diode on the panel surface, the performer or the like knows whether the switch contacts are open or closed, and then operates the push button for the desired switch to turn it on or off. At this time, the related mechanism between the switch knob and the contact operating lever is as shown in FIG. In FIG. 4, 1 is the panel surface, 2 is the board on which the switch etc. is attached, 3 is the push button switch body, 4 is the operation lever of the switch contact, 5 is the knob for the lever 4,
Reference numeral 6 indicates a light emitting diode, 7 indicates a light emitting diode mounting base, and 8 indicates a mounting stud between the board and the panel. The knob 5 surrounds the operating lever 4 and also surrounds the switch body 3 from above to the sides to form a hollow box shape. Also, above the operating lever 4 is a knob 5.
When the knob 5 is pushed down, the operating lever 4 is pushed down together with the knob 5, and the contacts of a switch (not shown) are turned on and off.

The light emitting diode 6 is mounted so as to be embedded inside the mounting base 7, and the lead wire of the light emitting diode 6 is in contact with the contact of the switch 3. Therefore, the on/off status of the contact of the switch 3 can be detected from the light emitting diode 6. It can be displayed by blinking. Further, the board 2 is attached to the panel surface 1 by mounting studs 8.

[Problem to be solved by the invention] In the configuration shown in FIG. 4, the knob 5 surrounds the outside of the switch operation lever 4, so the position of the knob 5 protruding from the panel surface 1 is the same as the position of the switch body 3. is almost the same. Therefore, for manufacturing purposes, it is necessary to make a large gap between the knob 5 and the panel surface 1, and the size of the gap is not uniform in the vertical and horizontal directions, resulting in an unsightly appearance. Also, the knobs 5 of the switches 3 were not aligned properly on the panel surface. Furthermore, when mounting the light emitting diode 6, a mounting base 7 is required, and if there is a failure in the diode 6 after installation, it is necessary to replace the mounting base 7 together with the light emitting diode 6.

The purpose of the present invention is to improve the above-mentioned drawbacks, and to provide a push-button switch operation mechanism in which the knob of the push-button switch is mounted at an accurate position on the panel surface, and the indicator lamp can be easily installed and replaced. be.

[Means for Solving the Problems] FIG. 1 is an exploded perspective view of the operating mechanism of a switch to show the principle structure of the present invention. In FIG. 1, 1 is a panel, 2 is a board on which a switch or the like is attached, 3 is a push button switch body, 5 is a switch knob, 6 is a light emitting lamp such as a light emitting diode, 8 is a mounting stud between the board and the panel, 9 1 is a hole in the panel surface from which a knob protrudes; 10 is a knob guide; 11 is a conical holding part for a light emitting lamp;
Reference numeral 12 indicates a guide hole that guides the movement of the knob.

The configuration of the present invention is as follows. That is, the push button switch 4 is equipped with a knob guide 10 that is attached to the back surface of the panel 1 and is composed of a conical holding part 11 that can hold the indicator lamp 6, and a guide hole 12 that guides the movement of the knob of the push button switch 4.
and the board 2 to which the indicator lamp 6 is attached, and the panel 1 to which the knob guide 10 is fixed,
The push button switch is arranged so that it can be operated by a knob 5 on one side of the panel.

[Function] In the mechanism configured as shown in FIG. 1, the panel 1 and the board 2 are opposed to each other by the studs 8, so the knob 5 is placed slightly away from the hole 9 on the surface of the panel 1 with the knob guide 10 fixed to the back surface. It stands out. Therefore, when the desired knob 5 is pressed while watching the blinking of the indicator lamp 6, the knob 5 moves toward the substrate 2 along the guide hole 12 of the knob guide 10. Then, the push button switch 4 is operated, so that the blinking of the display lamp 6 is reversed.

[Example] FIG. 2 is an enlarged view of only the knob guide 10 viewed from the opposite side from FIG. 1. In Figure 2, 5
10 is a knob that moves in the direction of the arrow; 11 is a conical holder for a light emitting lamp; 12 is a knob that moves in the direction of the arrow;
Reference numeral 13 indicates a guide hole that guides the movement of the knob 5, and 13 indicates a knob holding portion in which the guide hole is open. Second
Knob guide 10 and knob holding part 13 in the figure
are integrated and made of synthetic resin. 3 preferably has a protrusion 14 which is inserted into the knob guide hole 12 and is movable in the guide hole 12. The knob 5 is held by a knob holding portion 13 and is configured to be connected by a snap mechanism.

The mounting stud 8 in FIG. 1 is fixed to the back surface of the panel 1 by means such as welding. Also board 2
Insert a screw from the back side of the board through the hole provided in the board, and tighten the screw. This configuration is preferable because screws and the like are not visible on the surface of the panel 1.

A plurality of push button switches 4 are provided side by side on the board 2, and indicator lamps 6 are also connected correspondingly.

Although the push button switch and indicator lamp combination is often applied to electronic musical instruments, the present invention is not limited to electronic musical instruments.

[Effect of the invention] Thus, according to the invention, the knob for operating the push button switch is built into the knob guide in advance, and the knob guide is fixed to the panel, so that the knob for operating the push button switch is not placed on the panel surface. If the holes are opened in the correct positions, the knobs will be arranged neatly. There is no need to make the knob holes on the panel surface unnecessarily large, and the appearance is good. In addition, since the push button switch can be separated into the operating knob and the mechanism, even if the push button switch is misaligned on the board, it does not affect the arrangement of the knobs or the operation of the switch. . Furthermore, the display lamp can be held by the conical holding part and connected to the board only with a connecting wire so that the display can be displayed, making it easy to replace the lamp.
