As shown in FIG. 3A, the case 10 has a rectangular front surface. Hereinafter, the longitudinal direction on the front surface of the case 10 will be described as the vertical direction, and the short direction will be described as the horizontal direction.

  As shown in FIG. 4, a signal window 24 is opened on the upper surface of the case 10, and the light emitting element 52 is disposed to face the signal window 24. As the light emitting element 52, an infrared light emitting diode is used.

  As shown in FIGS. 1 and 2, a slot 25 into which a battery cover 53 for holding a battery (not shown) is inserted is opened on the lower surface of the case 10. A coin-type battery is used.

  The case 10 includes a base 20 having a base opening 21 formed on the front surface and a plate-like cover 30 that closes the base opening 21. The base 20 and the cover 30 are made of a synthetic resin molded product.

  The cover 30 includes a plate-shaped fixing portion 31 that covers a lower portion of the front surface of the base 20, and a plate-shaped operation handle portion 32 that is disposed above the fixing portion 31 and covers the upper portion of the front surface of the base 20. Through a single continuous connection. In the illustrated example, two left and right operation handle portions 32 are provided. A separation slit 32 b is formed between the operation handle portions 32.

  A pair of fitting pieces 33 projecting from the left and right ends of the rear surface of the fixing portion 31 are inserted into the base 20 and come into contact with the inner surfaces of the left and right walls of the base 20. A pair of upper and lower engaging claws 34 project from the outer surface of each fitting piece 33.

  On the inner side surfaces of the left and right walls of the base 20, fitting recesses 26 for fitting with the engaging claws 34 are respectively provided. Therefore, the fixing portion 31 is fixed to the base 20 by fitting the engaging claw 34 into the fitting recess 26.

  The hinge portion 35 is formed by being recessed in a groove shape from the front surface of the cover 30, and the operation handle portion 32 is swingably supported by the fixed portion 31 via the hinge portion 35. Further, an upper portion of the front surface of the operation handle portion 32 is an operation surface 32a to be pushed. In addition, the hinge part 35 can also be comprised as a thin part which couple | bonds the upper end part of the fixing | fixed part 31, and the lower end part of the operation handle part 32.

  As described above, the case 10 is formed by the cover 30 and the base 20, and the operation element 51 a of the push button switch 51 is pressed by a part of the cover 30 (operation handle portion 32). Thus, a wireless switch transmitter can be configured with two components, and a wireless switch transmitter with a small number of components can be provided. That is, compared to the conventional configuration that requires three parts, the thickness dimension (length dimension in the front-rear direction) of the case 10 can be reduced, and a wireless switch transmitter having a small thickness dimension can be provided.

  By the way, in the present embodiment, a plate-shaped middle cover 60 that is a synthetic resin molded product is disposed between the operation handle portion 32 and the substrate 50. The middle cover 60 is formed in a size that covers a portion of the base opening 21 that is not covered by the fixing portion 31. Therefore, it is possible to prevent the inside of the case 10 from being seen from the separation slit 32 b and to prevent foreign matter from entering the case 10.

  Middle cover openings 62 for penetrating the operation element 51 a of the push button switch 51 by the operation convex portion 37 are respectively penetrated at positions corresponding to the push button switches 51 in the middle cover 60.

  As shown in FIG. 5, a pair of upper and lower engaging projections 61 project from the left and right peripheral surfaces of the middle cover 60. As shown in FIGS. 1 and 2, engagement recesses 27 that fit into the respective engagement protrusions 61 are respectively provided in the inner side surfaces of the left and right walls of the base 20. Therefore, the middle cover 60 is fixed to the upper part of the base 20 by engaging the engagement convex portion 61 with the engagement recess 27.

  Two return pieces 63 project upward from the left and right ends of the peripheral wall on the lower side of each middle cover opening 62, and come into contact with the front end of the return piece 63 on the rear surface of each operation handle portion 32. A return convex portion 38 is projected. When the operation surface 32a is pushed, as shown by a two-dot chain line in FIG. 3B, the return piece 63 bends backward by the return convex portion 38, and the return piece 63 has a return force to the operation handle portion 32. Is granted. Accordingly, the return piece 63 assists the return of the operation handle portion 32, and the return of the operation handle portion 32 can be performed reliably.

  As shown in FIGS. 1 and 2, a locking piece 64 protruding downward is formed continuously and integrally above each middle cover opening 62 in the middle cover 60. On the other hand, a collar piece 39 is projected from a portion corresponding to the locking piece 64 on the rear surface of each operation handle portion 32. The hook piece 39 has a configuration in which a hooking portion 39b protrudes upward from a distal end portion of a leg portion 39a protruding from the rear surface of the operation handle portion 32. The cover 30 is attached to the base 20 so that the locking piece 64 is inserted between the rear surface of the operation handle portion 32 and the hook portion 39b of the collar piece 39.

  The thickness dimension in the front-rear direction of the locking piece 64 is set to be smaller than the distance between the rear surface of the operation handle portion 32 and the hooking portion 39b of the collar piece 39, and the rear surface of the locking piece 64 is on the front surface of the hooking portion 39b. The distance between the locking piece 64 and the rear surface of the operation handle portion 32 when abutting is the movable distance of the operation handle portion 32.

  Since the front surface of the hook portion 39b is in contact with the rear surface of the locking piece 64, the forward movement of the operation handle portion 32 is restricted, and a finger is applied to the peripheral surface of the operation handle portion 32 so that the operation handle portion 32 is moved. Even if pulled forward, the cover 30 does not warp.

  Further, even when the cover 30 is deformed in the hinge portion 35 in the form in which the operation handle portion 32 is tilted forward with respect to the fixed portion 31 at the time of assembly, the locking piece 64 is connected to the rear surface of the operation handle portion 32 and the hooking portion. By inserting it between 39b, the deformation of the cover 30 can be corrected.

  As described above, in the present embodiment, the return piece 63 and the locking piece 64 are formed on the inner cover 60, so that the return piece 63 and the locking piece 64 provided along with the operation handle portion 32 are attached to the base 20. There is no need to provide the base 20, and the shape of the base 20 becomes simple and the base 20 can be easily molded.

  Further, since the middle cover 60 is disposed between the substrate 50 and the operation handle portion 32, the length of the wireless switch transmitter in the front-rear direction is not increased by the middle cover 60.

  By the way, the wireless switch transmitter of this embodiment can be installed on a wall using a plate-shaped mounting holder 40. The mounting holder 40 has a rectangular front surface, and has a plurality of mounting holes 42 through which a plurality of mounting screws (not shown) are inserted from the front. The mounting holder 40 is fixed to the wall by mounting screws so that the rear surface is the wall surface side and the longitudinal direction is the vertical direction. A fitting projection 41 for detachably supporting the case 10 is provided in the center of the front surface of the mounting holder 40 along the vertical direction. Grooves 41a are formed in the vertical direction. On the other hand, a fitting groove 22 that fits into the fitting protrusion 41 of the mounting holder 40 is recessed in the center of the rear wall of the base 20 so as to open downward.

  The case 10 is attached to the front surface of the mounting holder 40 by fitting the fitting protrusion 41 into the fitting groove 22 from below the fitting groove 22. Therefore, the wireless switch transmitter can be attached to the mounting holder 40 and used as a wall switch.

  As described above, since the thickness dimension (length dimension in the front-rear direction) of the case 10 can be reduced, the protruding dimension from the wall surface when attached to the mounting holder 40 is reduced.

  Note that the number of operation handle portions 32 is not limited to two, and may be one or three or more.

(Embodiment 2)
In this embodiment, as shown in FIGS. 6 and 7, a fixing protrusion 65 for prohibiting the swinging of one of the two operation handle portions 32 is formed on the inner cover 60. This is different from the first embodiment. Other configurations are the same as those of the wireless switch transmitter according to the first embodiment.

  The fixing protrusion 65 protrudes from a portion of the front surface of the middle cover 60 that is above the right middle cover opening 62. The fixing protrusion 65 has a protruding dimension in which the tip abuts against the rear surface of the operation handle portion 32 in a state where the rear surface of the locking piece 64 abuts against the front surface of the hook portion 39b.

  In the example shown in FIG. 7, the right operation handle portion 32 is restricted from moving forward by the locking piece 64 and restricted from moving backward by the fixing protrusion 65, and as a result, swinging is prohibited. . Therefore, a wireless switch transmitter having one operation input unit and two wireless switch transmitters having an operation input unit can be realized in the same case 10 by simply replacing the middle cover 60. In the present embodiment, the example in which the swing of the right operation handle portion 32 is prohibited is shown, but the swing of the left operation handle portion 32 can also be prohibited.

(Embodiment 3)
8 and 9, the present embodiment is different from the first embodiment in that the intermediate cover 60 (see FIG. 1) is not provided and the return piece 63 ′ and the locking piece 64 ′ are formed on the base 20. . Other configurations are the same as those of the wireless switch transmitter according to the first embodiment.

  The return piece 63 ′ protrudes upward from the tip of the arm piece 66 that protrudes forward from a portion that is not covered by the substrate 50 in the upper part of the inner surface of the bottom wall of the base 20. The locking piece 64 ′ protrudes downward from the front end portion of the upper wall of the base 20. The return piece 63 'applies a return force to the operation handle portion 32 in the same manner as the return piece 63 (see FIG. 5) described in the first embodiment. The locking piece 64 ′ prohibits the forward movement of the operation handle portion 32, similarly to the locking piece 64 (see FIG. 5) described in the first embodiment.

  By forming the return piece 63 ′ and the locking piece 64 ′ on the base 20, the middle cover 60 is not necessary, and a wireless switch can be configured with a smaller number of parts than in the first embodiment.

  In the first embodiment, an example in which both the return piece 63 ′ and the locking piece 64 ′ are formed on the base 20 is shown. In the third embodiment, both the return piece 63 and the locking piece 64 are connected to the middle cover 60. The example formed in is shown. However, it is possible to adopt a configuration in which one of the return piece and the locking piece is formed on the base 20 and the other is formed on the inner cover 60. It is also possible to adopt a configuration in which the wireless switch transmitter has only one of a locking piece and a return piece. In this case, if the return piece or the locking piece is formed on the base 20 and includes the intermediate cover 60, it can be formed on the intermediate cover 60.
