[Problems to be solved by the device]

 By the way, in the above-mentioned conventional switch device, when it is attempted to change the layout of the contact part or increase or decrease the number of circuits, the mounting position and the number of the movable contacts to the movable members such as the slider and the rotor are changed, and the fixed contacts and Since it is necessary to change the mold of the housing formed by inserting the terminals, a corresponding design time and new capital investment including mold cost are inevitable, and the slide switch is changed to a rotary switch. When changing the operation method like this, even if the contact point had the same basic configuration, it had to be designed and manufactured as a completely different switch device. That is, the conventional switch device described above has a disadvantage in that the cost for the design change increases due to its structure.

The present invention has been made in view of the above-mentioned problems of the prior art, and an object thereof is to provide a switch device whose design can be changed easily and at low cost.

[0005]

[Means for Solving the Problems]

 The above-mentioned object of the present invention is to provide a housing made of a synthetic resin, push-operation type chip-type switch modules arranged at a plurality of locations on the inner wall of the housing, and a switch module electrically connected to the switch module. This is achieved by including a terminal projecting outside the casing and an actuator that is movably held by the casing and drives the switch module, and if necessary, a cam portion is provided to the actuator.

[0006]

[Action]

 According to the above means, the microminiature switch module made into a chip can be made to function as a contact portion, so that the movable member such as the slider or the rotor does not need a movable contact, and the switch module is arranged. The contact point can be specified only by considering the number of items and the number of items. Further, by disengaging the cam portion of the actuator from the operating portion of the switch module so as to drive the operating portion, even if the operating direction of the actuator and the operating direction of the switch module are different, there is a problem. Therefore, the degree of freedom in design is not impaired. Therefore, if microminiature switch modules can be installed in various places on the inner wall of the housing in advance, and if a plurality of them are appropriately selected and used as contact points for actually mounting the switch modules, The switch device makes it extremely easy to change the layout of the contacts and increase or decrease the number of circuits.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a cross-sectional view of a rotary switch according to a first embodiment of the present invention. A housing 2 made of synthetic resin integrated with a plurality of terminals 1 by insert molding, and a housing 2 of the housing 2. A push-operation type chip-shaped switch module 3 disposed at a plurality of positions on the inner bottom surface, a rotor 5 rotatably held by a housing 2 via a support shaft 4, and a central portion of the rotor 5. And a cover 7 made of a metal plate or the like, and an operating portion of the switch module 3 at a plurality of locations on the bottom surface of the rotor 5. A cam portion 5a for engaging and disengaging with 3a is provided in a protruding manner. In addition, on the inner bottom surface of the housing 2, element mounting portions 2a are provided in various places, which are capable of surface mounting the switch module 3 while ensuring electrical continuity with the terminal 1 projecting downward. The switch module 3 is actually surface-mounted at the position, but the remaining element mounting portion 2a is left blank. Further, the switch module 3 used here has a publicly known structure in which the operating portion 3a on the upper surface side can be raised and lowered and the operating portion 3a can be pushed to switch from the off state to the on state. However, it is extremely small with an external dimension of about 2 mm x mm.

In the rotary switch configured as described above, when the rotor 5 is rotated within the housing 2 via the operation element 6, each cam portion 5a is engaged with and disengaged from the corresponding microminiature switch module 3. The switch module 3 is turned on when the operating portion 3a is pushed into the cam portion 5a, and turned off when the cam portion 5a is detached from the operating portion 3a. Therefore, depending on the rotation angle of the rotor 5. Switching will be performed at multiple locations. In other words, since this rotary switch serves as a contact portion in which a plurality of microminiature switch modules 3 arranged on the inner bottom surface of the housing 2 are unitized, the rotor 5 drives each switch module 3. It only has to function as an actuator, and it is not necessary to attach a movable contact to the rotor as in the conventional product.

As described above, the above-described embodiment uses the microminiature switch module 3 that can be handled as a unitized switch element, and appropriately selects several points of each element mounting portion 2a in the housing 2. By mounting the switch module 3 on the switch module 3, the switch module 3 is made to function as a contact portion of the apparatus, so that the rotary switch can easily change the arrangement of the contact portion and increase or decrease the number of circuits. ..

Further, in the above embodiment, since the cam portion 5a is provided on the rotor 5 as an actuator, even if the operation direction of the rotor 5 is perpendicular to the operation direction of the switch module 3, the switch module 3 The operation part 3a can be driven smoothly.

Furthermore, in the switch device in which the microminiature switch module 3 is arranged as the contact portion as in the above-described embodiment, even when the operation method is changed, the common switch module 3 remains unchanged for the contact portion. Since it can be used, there is little waste in the design and manufacturing stages, and the operation method can be changed relatively easily.

FIG. 2 is a sectional view of a push switch according to a second embodiment of the present invention. In the figure, reference numeral 8 is a slider having a cam portion 8a at the bottom, and reference numeral 9 is a return spring, which corresponds to FIG. The same reference numerals are given to the parts that are shown.

That is, in this push switch, the microminiature switch modules 3 arranged at a plurality of positions on the inner bottom surface of the housing 2 are driven by the cam portion 8a of the slider 8 which is slidable inside the housing 2. Then, when the operator 6 which is integrated with the slider 8 as an actuator and projects to the outside of the housing 2 is pushed against the resilient force of the return spring 9, the cam portion 8a causes the operating portion of each switch module 3 to operate. Since it can be switched on and off by engaging with and disengaging from 3a, switching can be performed at a plurality of positions according to the pushing amount of the operator 6.

FIG. 3 is a cross-sectional view of a slide switch according to a third embodiment of the present invention. Similar to the second embodiment, the cam portion 8a of the slider 8 slidable in the housing 2 serves as a contact portion. The small switch module 3 is driven, and the operator 6 which is integrated with the slider 8 and protrudes above the housing 2 can reciprocate in the left-right direction in the long hole 7a of the lid 7. It has become.

FIG. 4 is a cross-sectional view of a lever switch according to a fourth embodiment of the present invention, in which the operating lever 10 pivotally supported by the housing 2 is rotated clockwise against the elastic force of the return spring 9. When it is rotated in the direction, the slider 8 having the pressing portions 8b projecting from a plurality of positions on the bottom surface descends inside the housing 2, and when the operating lever 10 is rotated by a predetermined amount, the pressing portions 8b come into contact with each other. It is designed to drive the microminiature switch module 3 which is a part.
