Description

[Detailed description of the invention] [Industrial application field] The invention is applicable to a slide/push switch,
That is, it relates to a switch that functions as a slide switch by sliding one button, and functions as a push switch by pressing this button.

[Conventional technology]

A conventional slide/push switch has a base, a movable contact piece made of a leaf spring fixed to the base in a cantilevered manner, and a fixed contact piece fixed to the base opposite to the movable contact piece. A switch is known that includes a push button that is slidably and pushably provided on a base (Japanese Utility Model Publication No. 16882/1982).

[Problem to be solved]

The above-mentioned conventional slide/push switch was not integrated into a unit and could not be incorporated into a manufactured product as is. Furthermore, since the fixed contact piece and the movable contact piece of the slide switch and push switch constitute the contact mechanism at the same location, there is a problem of lack of reliability.

Therefore, the purpose of the present invention is to provide a slide/push switch that can be made into a unit at the pre-assembly stage, can be incorporated into a product as is after being made into a unit, and has improved reliability of the slide switch and push switch.

[Means for Solving the Problems] In order to achieve the above object, the feature of the slide/push switch of the present invention is that a circuit board is fixed to the lower surface of the support plate. On the surface facing the support plate, there are formed a pattern in which the contacts of a push-type rubber switch come into contact with and separate from each other, and a pattern in which the contacts of a slide switch come in contact with and separate from each other. The swing lever is provided with a support arm that is swingably supported by a support plate at both ends, and a support arm that passes through a through hole in the support plate in the center and abuts on a rubber switch. A pressing shaft is provided, and a sliding body is provided above the swinging lever to be placed on the top surface of the swinging lever by its own weight.
A guide piece that supports the sliding body slidably in the longitudinal direction of the swing lever and a locking piece that prevents the sliding body from coming off upward are provided, and the sliding body is provided with a support plate. A hanging piece that passes through the window hole, faces the circuit board, and has a contact piece fixed to the end thereof, and a click shaft that engages with a click spring that is formed integrally with the support plate are integrally formed. It's there.

is fitted. A contact point 4 made of carbon material or the like is attached to the inner upper surface of the rubber button 4a so as to be able to come into contact with and separate from the pattern 2a. A pressing shaft 7c is provided in the center of the swinging lever 7 through a through hole 1h on the lower surface, and the pressing shaft 7c is formed so as to be able to come into contact with the rubber button 4a when the swinging lever 7 is pressed. It has been done. Above the swinging lever 7, a sliding body 8 made of plastic material is placed on the top surface of the swinging lever 7 due to its own weight. The protrusions 8a,... (see Fig. 4)
and the upper surface of the swing lever 7 are in contact with each other. On the upper surface of the support plate 1, four columnar guide pieces 1i, . . . are provided protrudingly, and four locking pieces 1k, .

In FIG. 3, on the longitudinal side surface of the sliding body 8, rising portions 8b protrude upward while facing the guide pieces 1i, so that the sliding body 8 cannot slide in the front-rear direction but can freely slide in the left-right direction. It is formed in Furthermore, a rib 8c is formed on the longitudinal side surface of the sliding body 8 to protrude horizontally and engage with the pawl 1j, so that the sliding body 8 cannot be removed upwardly and is slidable in the left-right direction.

In FIG. 4, a hanging piece 8d is attached to the lower surface of the sliding body 8.
A contact piece 6 is formed at the tip of the hanging piece 8d so that it can come into elastic contact with the circuit board 2 and can come into contact with and separate from the pattern 2b.
is fixed.

In FIGS. 1 and 2, the support plate 1 has a window hole 1l near the side plate 1b, and the hanging piece 8d is attached to the window hole 1l.
The contact piece 6 is in elastic contact with the circuit board 2. An irregularly shaped hole 1m is provided on the left side of the support plate 1 (see Fig. 1), and a pair of elastic click springs 1n, 1n are integrally formed in the irregularly shaped hole 1m and extend parallel to the center direction of the support plate 1. It is formed by At the tip of each click spring 1n, click spring 1n,
Head spacing l narrower than inner parallel part spacing L of 1n
Arc-shaped head portions 1p are formed to face each other so that. The swing lever 7 is provided with a rectangular through hole 7d opposite to the irregularly shaped hole 1m. A cylindrical click shaft 8e is integrally formed on the lower surface of the sliding body 8, and the click shaft 8e passes through the through hole 7d and the irregularly shaped hole 1m. The shaft diameter 8f of the click shaft 8e is formed so that L>8f>l, and the click shaft 8e is located at two locations on the left or right side (see Fig. 1) of the line connecting each head 1p, 1p. It is formed to be positionable. That is, a click mechanism C is constituted by a pair of click springs 1n, 1n and a click shaft 8e.

In FIG. 3, the left and right ends of the rib 8c are formed with four contact portions 8g, and each of the contact portions 8g is provided so as to be able to come into contact with the side portion of the guide piece 1i.

Next, regarding the operation of the switch of this invention, the first and third
To explain with the drawing, when the sliding body 8 is pushed to the right in FIG. 3, the sliding body 8 is moved to the right position by the click mechanism C with a click feeling. Furthermore, further rightward movement is restricted by the contact portions 8g, 8g hitting the guide pieces 1i, 1i of the support plate 1.
During this movement, the contact piece 6 moves toward the circuit board 2 shown in the first diagram.
Contact with the pattern 2b provided above establishes conduction, and the slide switch 5 made up of these is turned on.
state. Next, when you press the sliding body 8, no matter where you press the swinging lever 7, it will change if you press it downwards.
The pressing shaft 7c provided on the lower surface of the central portion of the swing lever 7 is pushed downward and presses the rubber button 4a fitted in the lower surface of the through hole 1h provided in the central portion of the support plate 1. , the contact 4 attached to the inside of the rubber button 4a comes into contact with the pattern 2a, turning on the push-type rubber switch 3 constituted by these.
state.

As an example of the actual use of the present invention, for example, since it is made into a unit at the pre-assembly stage, it can be installed on the top of the case of an alarm clock, and the sliding body 8 can be used to turn on and off the alarm.
The push-button rubber switch 3 can be used to display the time by voice and to turn on and off so-called snooze when an alarm occurs.

[Effect of idea]

As explained in detail above, according to the present invention, since it is made into a unit, it can be incorporated into a product as it is. Furthermore, since the slide switch and push switch are provided as separate members, the switch is highly reliable. Furthermore, a sliding body is mounted on the swing lever, and a pressing shaft is formed on the bottom surface of the swing lever so that it can come into contact with a rubber switch, and a contact point is provided on the inside surface of the rubber switch so that it can come into contact with and separate from the pattern on the board. This allows you to press the push switch reliably no matter where on the sliding body you press.
