Description

[Detailed description of the invention] The present invention provides an illumination lamp inside a switch case, and by pushing and pulling a push button, a movable contact is moved on an insulator provided with a fixed contact to cause a switch operation, and the illumination lamp is In an illuminated pushbutton switch in which the illumination light from a lamp passes through a translucent pushbutton, the switch operation, which is converted by pushing and pulling the pushbutton, can be displayed on the outside of the pushbutton by converting characters, symbols, etc. According to the improvement of the display device, a film provided with the above-mentioned several kinds of displays is moved in relation to the movement of the push button, and a display corresponding to the movement position of the push button is displayed on the outer surface of the push button using illumination light from an illumination lamp. It was designed to be photographed.

In an illuminated push button switch, a two-sided display plate with an L-shaped cross section is pivoted to the switch case between the push button and the illuminated lamp, and the display plate is activated by a push button that produces two movements, pushing and pulling. Swings reversibly,
Devices in which the display of characters, symbols, etc. displayed on the two sides can be changed are known. However, the above method can only be applied to a push button switch which performs an on/off switch operation simply by pushing and pulling a push button, but cannot be applied to a push button switch which performs a switch operation in three or more positions. The present invention relates to a display device that can be applied to a push button switch that moves a push button to three or more positions, and one embodiment thereof will be described with reference to the accompanying drawings.

In the figure, reference numeral 1 is a switch case with a push button for push/pull operation protruding from the front, and an insulator 2 is attached to the bottom of the rear part of the switch case, and a fixed contact 3,
4 and 5 are fixed at a certain pitch, an illumination lamp 6 is attached to the front side of the fixed contact group, and a film guide plate 8,
Attach 9 by fitting etc. Film guide plates 8, 9
is constructed on both sides of the rectangular tube 7 shown in FIG. It will be done. Film retaining pins 12 and 1 are provided at each inner end of the film guide plates 8 and 9.
A film 14 of an appropriate length is fixed to the switch case 1 in a cross-shaped manner, and the film 14 is passed through the narrow groove 10 of the film guide plate 8 and hung on the sliding surface 11, and then passed through the inner surface of the film guide plate 9. Both ends of the film are fixed to film fixing pins 12 and 13, respectively.

The push button 20 is formed in a rectangular tube 7 in the switch case 1 to a length that extends over the insulator 2, and has a long through hole on the surface corresponding to the film guide plates 8 and 9 through which the illumination lamp 6 also passes. 21, and a contact holder 22 is integrally formed or attached to the rear end. The contact holder 2
2 is provided with a mounting groove 23 for a movable contact 25 that moves back and forth on the insulator 2, and a through hole 24 is formed in which a contact pressure spring 26 applied to the movable contact 25 is fitted. The engagement ball 27 that has come into contact with the upper end of the switch case 1 is engaged with one of the engagement grooves 15, 16, and 17 provided at a constant pitch on the inner surface of the switch case 1.

The movable contact 25 is moved to the off position (), the first load drive position (), and the second load drive position () by pushing and pulling the push button 20 that engages the engagement ball 27 with any of the engagement grooves 15 to 17. Move to either. Further, rollers 28 and 29 are attached to the inner end of the push button 20 to move on the inner surface between the film guide plate 8 and the film guide plate 9, and the film 14 hung on the sliding surface 11 of the film guide plate 8 is moved behind the roller 28. Hang the film 14 on the side and press the button 20.
The lens 30 fitted in the lens 30 is hung across the front side of the roller 29.

The film 14 may be a non-transparent film, and is provided with translucent displays 14a, 14b such as letters and symbols indicating switch operation when the push button 20 moves to each position () to (). , 14c, and when the push button switch of the present invention is used in a vehicle headlight circuit, it can be set to ``OFF'', ``LOW'',
Display the three types of "HIGH" indications as shown in Figure 5, and press each of the indications on the lens 3 of the button 14.
0 and the illumination lamp 6.

In the present invention, when the push button 20 is pulled to the position () in FIGS. 1 and 2, the film 14 is guided by the rollers 28, 29 and the sliding surface 11, and the lens 3
The display 14a is moved to the rear surface of the lens 3, and the illumination light from the illumination lamp 6 is transmitted through the display 14a and projected onto the front surface of the lens 3. When the push button 20 is pressed and moved to the position (), the display 14b moves to the rear surface of the lens 30, and when the push button 20 is moved to the position (), the display 14c moves to the rear surface of the lens 30. The movement of the film 14 is controlled by the push button 20 in relation to the pulling operation, and the display 14a is
~14c is converted to correspond to each position () to ().

As clarified by the above description, the present invention
When the push button 20 of the push button switch is pushed or pulled, the film 14 is moved between the push button 20 and the illumination lamp 6, and the display corresponding to the position of the switch operation is moved to the rear of the push button 20 and displayed on the front. The operating status of the switch is clearly displayed by projecting a display, and since the film 14 can be made long and three or more displays can be provided, a push button switch that moves the push button to two positions is Of course, for push-button switches that move to more than three positions and provide a variety of switch operations, the length of the film 14 and the number of markings that appear on the film at intervals related to the pitch of movement of the push-button and movable contact can be changed. , can be applied freely.
