(Embodiment 2) The push button switch in this embodiment is basically the same as that in the previous embodiment, but the details are different, so even parts having the same function are given different numbers. 8th
The figure shows a cross-sectional view.

The push button switch includes a case body 1 that houses a contact opening/closing mechanism. Figure 5 shows the state of the case body 1 seen diagonally from above with other parts assembled, and the case body 1 seen diagonally from above with most of the switches left in place and almost as a single item. The state is shown in Figure 4. As seen in these figures, the case body 1 is formed using a resin material and includes as its main parts a rectangular base plate part 2 and a boss part 3 that projects downward from the center thereof as a square tube. . At the center of the base plate part 2, four storage parts 4 are formed which have a rectangular opening when viewed from above. The storage recess 4 is formed so that the protruding portion of the boss portion 3 is partitioned by a partition wall 5 in the middle, and is open upward. Projections 6 having a semicircular cross section are provided on all sides of the base plate 2 at a portion corresponding to the outer periphery of the four storage parts 4.
A sealing protrusion 7 is provided so as to surround the outer periphery of the container in a quadrilateral shape when viewed from above. An engagement groove 8 is formed on the inner periphery of this sealing protrusion 7.

A flexible inner cover 10 made of rubber or a special soft vinyl chloride resin material is installed in the center of the base section 2 so as to be concentric with the four storage sections 4. This inner cover 10 has a raised flexible portion 11 in the center and a sealing 7-run hole W112 on its outer periphery. The flexible portion 11 has a recess l in its protruding interior corresponding to the upper part of the storage recess 4! 1Is 13 on the inside, and these gates 13 and storage recess 4 form one sealed space. A protrusion 14 (in the figure, it is pushed into the protrusion 6 and is recessed) that contacts the protrusion 6 from above is formed on the back surface of the sealing 7 run part 12, and also forms a protrusion 14 on the outermost periphery of the seal 7 run part 12. The above-mentioned famous person f
! An entry protrusion 15 is formed that enters into the ItB.

The upper surface of the sealing 7 run part 12 is pressed against the upper surface of the sealing ridge 7 of the base part 2 by a presser plate 17 so that it is at the same height, and this presser plate 17 and the sealing ridge 7 are bonded together. The material is fixed by being bonded using an adhesive or an ultrasonic heat bonding method. Thereby, the space between the base plate part 2 and the visible part 11 is sealed, and the switch main body (contact opening/closing mechanism) 20 is housed in this sealed space.

This switch body 20 is a microgap switch, and is installed on a printed board 23 attached within the four storage parts 4. The actuator 21 protruding from the switch body 20 is close to the back surface of the flexible portion 11, and the printed board 23 has lead wires 24 electrically connected to the switch body 20 as shown in FIG. The tips are connected. This lead #1I24 is connected to the partition wall 5
The wires are led out to the outside through wire insertion holes 25 formed in the wires, respectively, and are connected to, for example, an alarm device (not shown). An embedded recess 26 is formed at a location of the boss portion 3 corresponding to the outside of the partition wall 5, and an adhesive 27 is embedded in this embedded recess 26. This adhesive 27 completely prevents moisture from entering from the mounting box side.

On the other hand, an exterior cover 41 is provided on the upper surface of the case body 1.
A cover engaging protrusion 32 is provided which is disposed to engage with the cover engaging protrusion 32 . The handle 35 is attached to the exterior cover 4 as in the previous embodiment.
A collar 28 for preventing removal is formed on the outer periphery of the handle 35, and grooves 29 are formed respectively.

The claw 25 located in the groove 29 of the handle 35 is connected to the exterior cover 4.
It is formed integrally with 1. The handle 35 is pushed up by the biasing force of the cutter 21 of the switch body 20. Due to the reciprocating movement of the handle 35, the pressing protrusion 36 protruding from the center of the back surface of the handle 35 moves the flexible ff1s1.
1, the actuator 21 is pushed down to turn the switch body 20 on and off. When the user stops pushing the handle 35, the handle 35 returns to its original position due to the return force of the actuator 21.

A body peripheral edge protrusion 39 having an inverted (■-shaped cross section) is formed on the outer circumferential edge of the case body 1.
A waterproof gasket 40 and an exterior cover 41 are fitted and attached via 9.

The waterproof packing 40 is formed into a four-sided frame shape from a special soft vinyl chloride resin material or a rubber material,
A fitting projection 42 protruding from the upper surface thereof is fitted into a fitting receiving groove 43 formed on the back side of the body peripheral edge projection 39. The waterproof gasket 40 is provided with a groove 44 on its back surface, and is designed to effectively adhere to the surface of construction materials such as bathrooms.

Fixing the case body 1 to a mounting box buried in a construction surface as described above is generally used. This is done directly using the mounting screws 46, as shown in FIG. 5, without using a mounting frame. The mounting screws 46 are screwed to the front surface of the mounting box, and as the case body 1 is fixed to the construction surface by the mounting screws 46, the waterproof gasket 40 comes into close contact with the construction surface.

As shown in FIG. 6, the exterior cover 41 has an opening 47 in the center, and a rectangular contact step 4 on its outer periphery.
It has 8. An operation sheet 49 made of a polycarbonate resin film is attached to this contact step g48 by adhesion (or welding). When this operation sheet 49 is pushed and repeated, the flexible Ell is pushed down via the handle 35, and when the operation sheet 49 is returned, the handle 35 returns to its original position. As a result, the switch body 20 is turned on and off. Such an exterior cover 41 is
It fits onto the outer periphery of the case body 1 and also engages with the cover engagement protrusion 32, whereby the exterior cover 4
1 is detachable and also seals the internal space to the outside. Note that this exterior cover 41 may be a so-called decorative plate.

The epJS diagram shows a specific method of mounting the case body 1 of the pushbutton switch, and there are mounting holes 45 in the case body 1 corresponding to the screw holes 31 for mounting the mounting box 30 buried in the construction surface 33. By inserting a mounting screw 46 into this mounting hole 45 and screwing it into the screw hole 31 of the mounting box 30, the case body 1 can be mounted without using a mounting frame like a general wiring device. It can be attached to the construction surface 33. In other words, this case body 1
has the function of a mounting frame, eliminating the need for a mounting frame. Incidentally, upon installation, caulking is applied to the back surface or the surrounding area of the case body 1. tJS10
In the figure, L-shaped mounting holes 45a are formed at the four corners around the case body 1, and the case body 1 is mounted from the front into the mounting holes 45a using so-called scissors. In this way, in this embodiment, the number of parts such as the mounting frame and the plate screws for attaching the instrument to the mounting frame can be reduced, and therefore costs can be reduced. Also, when installing, attach the mounting frame to the mounting box 30.
Since the installation work can be omitted, it is expected that the construction work will be more efficient.

[Effects of the Invention] As described above, the present invention provides a push button switch that has a case body and a cover that house a contact opening/closing mechanism, and turns on/off the contact opening/closing mechanism by pressing and repeating a handle. ) The handle of the cover is inserted into the holding means that holds the handle movably with respect to the contact opening/closing mechanism. By providing a holding means to hold the handle on the side of the opening of the cover, molding can be done without using a slide or other means as in the conventional method. This has the effect of reducing mold costs and reducing parts costs by shortening the molding cycle.
