[The best form of implementing the invention]

Hereinafter, embodiments of the switch of the present invention will be described in detail with reference to the drawings. The switch 1 of this embodiment is a switch used in combination with the key grip 2 in the same manner as the conventional example described in Patent Document 1. Among them, unless otherwise specified in the following description, as shown in FIG. 2, the directions of up, down, left, right, forward, and backward are prescribed.

This switch 1 includes a rectangular box-shaped body 10 made of a synthetic resin molded body. The device body 10 is configured by combining a switch body 11 opened in the front and a switch cover 12 opened in the rear.

The switch cover 12 includes a rectangular hole 120 that is opened to the right from the center in the longitudinal direction of the front surface. Then, a button handle 13 is disposed in the hole 120 so as to be movable in the front-rear direction.

In addition, a pair of shaft portions (supporting portions) 121 are arranged in a row on the left side of the front face of the switch cover 12 in the up-down direction. Each of these shaft portions 121 has a front end portion formed in a cylindrical shape, and a bearing portion (not shown) of the keyboard handle 2 is rotatably mounted on the front end portion.

In addition, the switch cover 12 includes a pair of mounting hooks 125, which are respectively provided on the left and right side surfaces, and are arranged in the up-down direction with a gap.

Although not shown, the contacts and the switching mechanism for switching the states of the contacts are housed in the container 10. The switching mechanism is configured as follows: each time the button handle 13 is moved into the body 10 by a pressing operation, the state of the contact (for example, the state of the contact closed (the state where the movable contact is in contact with the fixed contact)) and the contact The disconnected state (state where the fixed contact and the movable contact are separated) is switched. Among these, the aforementioned contacts and the aforementioned switching mechanism are disclosed in the conventional example described in Patent Document 1, and are known in the past, so illustrations and descriptions of their detailed structures are omitted.

The key grip 2 is formed in a rectangular flat plate shape from a synthetic resin material. Further, the key grip 2 has the aforementioned bearing portion provided on the left rear side. Further, the key grip 2 includes a pair of detachment prevention pieces 20 which are provided at the center in the upper and lower direction of the right end and protrude rearward. These detachment prevention pieces 20 are configured as follows: they are inserted into the gap 123 in the switch cover 12 through the insertion hole 122 formed in the front face of the switch cover 12, and a hook (not shown) provided at the front end is hooked to the insertion Perimeter of hole 122.

As shown in FIGS. 4 and 5, the switch 1 configured as described above uses the mounting frame 3 and a plate (hereinafter referred to simply as a plate) 4 for wiring appliances, and is embedded in a building material such as a wall.

The mounting frame 3 is formed of a synthetic resin or a metal plate into a rectangular frame shape having a window hole (not shown) for mounting equipment. The mounting frame 3 includes a pair of vertical pieces 30 along the longitudinal direction (up and down direction), and a pair of horizontal pieces 31 connecting both ends of the pair of vertical pieces 30 to each other. That is, a space surrounded by the pair of vertical pieces 30 and the pair of horizontal pieces 31 forms a window hole.

As shown in FIG. 5, the pair of longitudinal pieces 30 has a plurality of (eight in the example of illustration) appliance mounting holes 300. Each of these appliance mounting holes 300 is inserted with a pair of mounting hooks 125 protruding from the left and right sides of the switch 1. That is, the switch 1 is mounted on the mounting frame 3 (see FIG. 4) by inserting the pair of mounting hooks 125 into the pair of appliance mounting holes 300 and inserting the front end of the body 10 into the window hole. And Figure 5).

The mounting frame 3 is mounted on a switch box (not shown) embedded in the wall, with the pair of lateral pieces 31 abutting the periphery of the embedding hole provided in the wall, for example. That is, two bolts (not shown) inserted through the holes (not shown) of the screws inserted into each of the lateral pieces 31 are screwed into the screw holes of the switch box. Among them, when the switch box is not embedded, the mounting frame 3 is fixed to the wall panel using a conventionally known holding metal (not shown).

The plate 4 includes a plate body (not shown), which is mounted on the mounting frame 3, and a plate cover 40, which is detachably mounted on the plate body to cover the plate body. As shown in FIG. 4, the sheet cover 40 has a front wall 400 and a side wall 401 integrally configured as a synthetic resin molded body. A rectangular window (not shown) is provided through the center of the front wall 400.

Furthermore, excluding the key handle 2 inserted through the window, the plate cover 40 covers the switch 1, the mounting frame 3, the plate body, and the buried hole from the front. In addition, the key handle 2 can be operated from the front through the window of the sheet cover 40.

When a backward force (hereinafter referred to as an operating force) is applied to the key handle 2 mounted on the switch 1, the key handle 2 is rotated with the shaft portion 121 as a fulcrum, and the button handle 13 of the switch 1 is pressed in a backward direction. Then, the button handle 13 is pushed into the body 10, and the state of the contact is switched. When no operating force is applied to the key grip 2, the button grip 13 moves outside the body 10. At this time, the key handle 2 pressed by the button handle 13 is rotated away from the front surface of the switch 1, and the claws of the pair of detachment prevention pieces 20 are stopped at the position around the periphery of the insertion hole 122 (see FIG. 1).

In addition, as shown in FIG. 4, in a state where no operating force is applied to the key grip 2, the front wall (surface) 400 of the sheet cover 40 projects approximately evenly forward. On the other hand, in the conventional example described in Patent Document 1, the amount of protrusion of one side (farther from the pivot point) from the front wall of the plate is increased without operating force being applied. . Therefore, in the conventional example, as long as the key handle is pressed until the aforementioned side is completely flush with the front wall of the plate, the state of the contact point of the switch can be switched. In contrast, the switch 1 of this embodiment does not switch the state of the contacts until the key handle 2 is pressed further (deep) than the front wall 400 of the sheet cover 40. Therefore, in this embodiment, there is a high possibility that the key grip 2 is excessively pressed and an excessive operating force is applied.

Here, the switch 1 of this embodiment includes a stopper 124 provided on the front right end of the device body 10 (switch cover 12). The stopper 124 is a rectangular parallelepiped-shaped protrusion, and two stoppers 124 are provided at intervals, so as to be sandwiched by a pair of insertion holes 122.

Then, when the key handle 2 is rotated by the operation force, the key handle 2 abuts against the front end of the stopper 124 provided on the front surface of the body 10, and at this position, the rotation of the key handle 2 is restricted (see FIG. 3). ). That is, since the rotation of the key grip 2 is restricted by the stopper 124, the range in which the key grip 2 pushes the button grip 13 in the backward direction is also restricted. Therefore, even if an excessive operating force is applied to the key grip 2, it is possible to avoid applying an excessive force to the button grip 13.

As described above, the switch 1 of this embodiment includes: a box-shaped body 10; contacts stored in the body 10; and a button handle 13 having a portion exposed from the front surface of the body 10 and provided. When this part is subjected to external force, it can move into the body 10. In addition, the switch 1 of this embodiment includes a switching mechanism which is housed in the device body 10 and switches the state of the aforementioned contacts by moving the button handle 13 into the device body 10. Furthermore, the switch 1 of this embodiment includes a support portion (shaft portion 121), and a handle (key handle 2) larger than the button handle 13 is supported so as to be rotatable along the front-rear direction of the body 10. The button handle 13 is configured as follows: When the handle (key handle 2) is rotated toward the front surface of the body 10, it is pushed by the handle (key handle 2). A support portion (shaft portion 121) is provided on one end side of the front surface of the body 10, and the switch 1 has a stopper portion 124 provided on the other end side of the front surface, and pushes the handle (key handle 2) to the range of the button handle 13 Be restricted.

Since the switch 1 of this embodiment is configured as described above, the rotation range of the key grip 2 is limited by the stopper 124. Therefore, the switch 1 of this embodiment can suppress an excessive force from being applied to the button handle 13.

In addition, in the switch 1 of this embodiment, the stopper 124 is preferably configured as follows: when the handle (key handle 2) is provided in the body 10 and rotates in a direction close to the front face of the body 10, it abuts against the handle (key Handle 2). With the above structure, both the handle (key handle 2) and the body 10 are subjected to an excessive force applied to the handle (key handle 2), and the handle (key handle 2) can be prevented from being damaged.

In addition, in the switch 1 of the present embodiment, two stopper portions 124 are provided in the body 10, but the stopper portions 124 may be one or three or more.
