Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an interlocking pushbutton switch, in which interlocking pushbuttons, for example, pushbuttons that are interlocked via a swinging member are arranged side by side.

BACKGROUND ART Conventionally, arms protruding from both sides of a swinging member that is swingably supported in a switch case are suspended from the lower surface of the substantially center of two push buttons arranged in parallel on the upper surface of the case. An example of an interlocking push button switch that is connected to each operating rod so that the push buttons move in mutually opposite directions is disclosed in Japanese Utility Model Application Publication No. 52-138383.

That is, the conventional technology disclosed in the above publication is
A cam is rotatably fitted onto a shaft protruding from the side wall of the case, and each protrusion protruding from the side surface of both wings of the cam is fitted into a hole drilled in the push rod portion of each push button.

The cam is gradually assembled from the open side of the case while determining the positions of the shaft and the two holes, and the positions of the corresponding parts.

Problems that the invention aims to solve In the conventional interlocking push button switch with the above configuration,
When connecting the push rod part of each push button and the cam, it was very difficult to assemble, especially when the periphery of the case was closed and only the pole side was open. .

This invention was devised to solve the above problems, and even if the area around the case is closed,
Push buttons and swingable connections can be easily made, and
The object of this invention is to provide an interlocking pushbutton switch that fully satisfies the conventional functions, and this object is based on the problems that the present invention attempts to solve.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention has a structure in which arms protruding from both sides of a swinging member that is swingably supported in a closed switch case are arranged in parallel. In the interlocking push button switch, the two push buttons are engaged with connecting grooves provided on the sides of each actuating rod, so that the two push buttons are interlocked in vertically opposite directions. The opposing surfaces of the comrades and the side surfaces perpendicular to the opposing surfaces are respectively configured as openings,
The switch case constitutes an interlocking push button switch characterized in that it is provided with a guide wall that guides each of the arm portions in the direction of the connection groove.

Operation With the above configuration, when assembling the swinging member to the operating rod of each push button, after assembling each push button to the switch case, open the switch case opening so that the push button is located on the lower side. Turn it upward. Next, the swinging member is dropped into the switch case from the opening in a predetermined posture along one side wall, and then guided by the guide wall and slid in the direction of the connecting groove of the operating rod. The engaging element at the tip of the arm of the member is inserted into the connecting groove of the operating rod of each push button, completing the assembly.

Therefore, the push buttons 2 and 3 are connected by the swinging member 4 and always operate in the opposite mode. That is, when one push button 2 is pressed to the ON position, the other push button 3 is pushed up from the ON position to the OFF position via the swinging member.

Embodiment An embodiment of the interlocking push button slide according to the present invention will be described based on FIGS. 1 and 2.

Reference numeral 1 designates a switch case that is open only on the lower side, and a hole 1 is provided in the upper surface of the switch case 1 through which operating rods 21 and 31 of push buttons 2 and 3, which will be described later, are inserted.
1 and 12 are drilled. Further, the lower side of the switch case 1 is formed with an opening 13 into which a pole plate 6, which will be described later, is fitted. Furthermore, as shown in FIG. 2, an arcuate groove 14 is provided inside the switch case 1, in which an upper portion of a swinging member 4, which will be described later, is disposed. Guide walls 15, 15 that guide the arms 42, 43 of the swinging member 4 along the arcuate groove 14 when the swinging member 5 is assembled.
is provided.

Reference numerals 2 and 3 designate push buttons which are biased on the upper surface of the switch case 1 by springs 23 and 33, and the push buttons 2 and 3 are provided with operating rods 21 and 31 that hang down from their lower central portions. The operating rod 21, 3
1 has an opposing surface 2 on its side as shown in FIG.
Connecting grooves 22, 32 are formed in which openings are formed in the connecting grooves 2a, 32a and the side surfaces 22b, 32b perpendicular to the opposing surfaces 22a, 32a, respectively.

Reference numeral 4 denotes a swinging member, and the swinging member 4 is swingably supported by the switch case 1 via a pin 5, using a hole 41 bored in its main body as a fulcrum. At that time, a tube 4 is provided between the swinging member 4 and the inner wall of the switch case 1 to prevent the pin 5 from moving in the axial direction.
7 is interposed. Further, on both sides of the swinging member 4, the connecting grooves 22 of the aforementioned operating rods 21, 31,
Engagement element 42 having a circular cross section is inserted into 32.
Arm portions 42 and 43 having tips a and 43a are provided. Further, a slider 46 biased by a spring 45 is provided in a hole 44 bored in the lower part of the swinging member 4 . Reference numeral 6 denotes a pole plate fitted into the opening 13 of the switch case 1, and the pole plate 6 includes a movable contact piece 61 that is moved by the slider 46, a fixed contact piece 62, and lighting lamps 63, 63.
and a terminal 64.

Next, a working process for assembling the push buttons 2 and 3 and the swinging member 4 in the interlocking push button switch having the above structure into the switch case 1 will be explained.

First, the springs 23, 23 and push buttons 2, 3 are assembled from the upper side of the switch case 1.

Next, as shown in FIG. 2, with the opening 13 of the switch case 1 facing upward,
is pushed into the switch case 1 and held.

Next, after dropping the swinging member 4 onto the guide walls 15, 15 from the upper side shown in FIG.
Slide in the 1 and 31 directions. That is,
The arms 42 and 43 of the swinging member 4 are first placed on the guide walls 15 and 15, and then the engagers 42a and 43a of the swinging member 4 are placed on the guide walls 15 and 15.
The side surfaces 22b of the operating rods 21, 31 are guided by the
It is inserted into the connecting grooves 22, 32 from the 32b side.

Next, by assembling the tube 47 and the pin 5, the assembling of the push buttons 2, 3 and the swinging member 4 is completed.

In the interlocking pushbutton switch having the above structure, the pushbuttons 2 and 3 are connected by the swinging member 4, so that they operate in the opposite mode. In other words, one push button 2 is ON.
position (the state shown in Figure 1), the other push button 3 is
When the push button 2 is in the OFF position, the other push button 3 is in the ON position.

Effects of the Present Invention As detailed above, according to the structure of the present invention, the operating rod of each push button and the swinging member are connected to each other in the switch case with the surroundings closed, and the swing member is connected to the guide wall of the switch case. Simply insert it until it makes contact, and then slide it into the connecting groove of the operating rod using this guide wall as a guide to complete the insertion.
Therefore, positioning and connection work between the operating rod and the swinging member in a narrow space such as a switch case becomes extremely easy.
