Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mounting structure for an alternate switch device.

[0002]

[Prior Art]

 FIG. 3 shows a conventional example of an alternate switch device.

In the figure, reference numeral 1 is a circuit board, on which a rubber sheet 2 is laminated and a rubber contact switch 3 is provided. The laminated body of the circuit board 1 and the rubber sheet 2 is housed in the case 5, and the rubber contact switch 3 is attached to the mounting opening 6 formed in the upper case 5 at a position facing the rubber contact switch 3. An operating body 7 that operates by an alternate operation is provided. The operating body 7 includes an upper operating portion 8, a return spring 10 mounted on a shaft portion 9 of the operating portion 8, a striker 11 into which the lower end of the shaft portion 9 of the operating portion 8 is inserted and fixed, and a striker 11. The striker 11 has a plunger 13 mounted therein via a contact pressure spring, and a side face of the striker 11 is provided with a heart cam mechanism (not shown) for the alternate operation. Below the mounting opening 6 of the case 5, there is integrally provided a cylindrical body 14 positioned so as to surround the striker 9, and at a position of the cylindrical body 14 opposed to the heart cam mechanism, the heart cam mechanism is engaged. Then, the striker 11 performs an alternate operation. The elastic engagement convex portion not shown in the figure is provided. Reference numeral 16 is a makeup cover, and the operation portion 8 is exposed from an opening 17 of the makeup cover 16.

With the above-mentioned configuration, when the operating portion 8 is pushed in, the engagement state of the rubber contact switch 3 of the plunger 11 is maintained by the engagement of the engagement convex portion of the striker 11 with the heart cam mechanism. When the portion 8 is pushed in, the engaging convex portion is disengaged from the heart cam mechanism, the plunger 13, the striker 11, and the operating portion 8 are integrally returned, and the pressing of the rubber contact switch 3 is also released.

[Problems to be solved by the device]

 However, in the configuration in which the operating body 7 is mounted on the upper case 5 as described above, there is a problem that the mounting work is very troublesome.

That is, since the operating portion 8 and the striker 11 which are larger than the mounting opening 6 are arranged on the upper surface side and the lower surface side of the upper case 5, the shaft portion 9 of the operating portion 8 is fitted and connected to the striker 11. The work had to be performed with the upper case 5 sandwiched between them, and it was difficult to align the respective parts and it took a lot of time and effort to fit and connect. Especially, when a plurality of such switch devices are collectively arranged, the workability is extremely deteriorated. Further, the assembly of the switch device is performed by incorporating the laminated body of the circuit board 1 and the rubber sheet 2 into the case 5 in which the operating body 7 is mounted, so that the operating body 7 becomes an obstacle at that time. It was sometimes damaged.

The present invention has been made to solve the above problems, and an object thereof is to provide an alternate switch device which can be obtained by a simple assembly configuration.

[0008]

[Means for Solving the Problems]

 In order to achieve the above object, in the present invention, an alternate switch device is provided with a switch element in a case, and a mounting surface for mounting an operating body of a switch element is provided on a case surface facing the switch element. In this opening, a housing having an insertion hole for an operation portion, an operation body that is mounted in the housing such that it can operate in an alternate manner, and has a lower end serving as an operation portion of the switch element, and one end inserted from the insertion hole, the operation body A switch element operating body composed of an operating portion connected and fixed to the switch element is fitted and configured.

[0009]

[Action]

 According to the above configuration, the alternate switch device can be configured by fitting the switch element operating body, which is a combination of the housing, the operating body, and the operating portion, into the mounting opening provided on the case surface.

[0010]

【Example】

 FIG. 1 is an exploded perspective view of an alternate switch device of the present invention, and FIG. 2 is a vertical sectional view.

Reference numeral 20 denotes an operating body, and the operating body 20 has an upper operating portion 21, a return spring 24 attached to a shaft portion 23 of the operating portion 21, and a lower end of the shaft portion 23 of the operating portion 21 inserted therein. A housing 26 having an insertion hole 25, a striker 28 movably mounted in the housing 26 for alternate movement, and a plunger 31 mounted in the striker 28 via a contact pressure spring 30 are provided on the side surface of the striker 28. A heart cam mechanism 33 for alternator operation is attached. At a position of the housing 26 opposed to the heart cam mechanism 33, there is provided an elastic engagement convex portion which is engaged with the heart cam mechanism 33 and performs an alternate operation on the striker 28 side, which is not shown in the figure.

A rubber contact switch 42 is formed by laminating a rubber sheet 41 on a circuit board 40, and a laminated body of the circuit board 40 and the rubber sheet 41 is housed in a case 44. A mounting opening 45 for the operating body is formed on the surface of the case 44 facing the 42. A pair of hanging walls 47 are integrally provided on the inner periphery of the mounting opening 45, and engaging holes 48 are provided in the hanging walls 47, respectively.

The operation body 20 integrally assembled is fitted into the mounting opening 45 formed in this manner from above, and the engaging portions 50 formed to project on both surfaces of the housing 26 respectively engage with the engaging holes. It is fitted in the mounting opening 45 by being engaged with each of the 48.

In this way, the alternate switch device is simply configured by fitting the preassembled operating body 20 into the mounting opening 45 on the surface of the case 44.

[0015]

[Effect of the device]

 According to this invention, the alternation switch device can be configured by fitting the operating body of the switch element, which is a combination of the housing, the operating body, and the operating portion, into the mounting opening provided on the case surface. , It is not necessary to assemble the switch device while mounting it on the case surface, so an alternate switch device can be obtained very easily.
