Abstract

(57) [Summary] [Purpose] To obtain a switch unit that can prevent erroneous operation. [Structure] The panel on which the switch is mounted is provided with a depressed window through which the operation portion of the switch can be operated, and when the switch is mounted, the operation portion of the switch is inside the surface of the panel.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a switch unit capable of preventing erroneous operation.

[0002]

[Prior Art]

 3 and 4 are a front view and a side view showing a conventional switch unit. In the drawings, 1 is a switch, 1a is an operation lever, 2 is a panel to which the switch 1 is attached, and 3 is the switch 1 is housed. The frames 4 and 4 are protective covers detachably attached to the panel 2.

Next, the operation will be described. The switch units of FIGS. 3 and 4 are provided with a protective cover 4 for covering the operating portions 1a of the plurality of switches 1 so as to protect the operating portions 1a, and the operating portions 1a are inadvertently operated. To prevent erroneous operation, when operating the switch 1, the operation portion 1a is operated after removing the protective cover 4.

[0004]

[Problems to be solved by the device]

 Since the conventional switch unit is configured as described above, since the protective cover 4 projects from the surface of the panel 2, there is a problem that the installation space becomes large, or when it is necessary to operate the switch 1 urgently. However, after removing the protective cover 4, the operation section 1a must be operated, which causes a problem that operability is deteriorated.

The present invention has been made in order to solve the above problems, and a switch in which the operation portion of the switch is prevented from coming out of the surface of the panel and an erroneous operation due to careless contact can be prevented. Aim to get a unit.

[0006]

[Means for Solving the Problems]

 In the switch unit according to the present invention, the panel on which the switch is mounted can be operated with the switch operation part, and the switch operation part is provided with a recessed window inside the panel surface when the switch is installed. It is a thing.

[0007]

[Action]

 In the switch unit according to the present invention, the operation portion does not protrude from the surface of the panel, and the operation portion can be operated in the depressed window.

[0008]

【Example】

 Example 1. An embodiment of the present invention will be described below with reference to the drawings. 1 and 2, 1 is a switch, 1a is an operation part, 2 is a panel to which the switch 1 is attached, 2a is a depressed window having an opening through which the operation part 1a can be operated, and a peripheral wall is a height of the operation part 1a. It is configured higher than that. Reference numeral 3 is a frame in which the switch 1 is housed, and the panel 2 is attached to the frame 3.

Next, the operation will be described. In the switch units of FIGS. 1 and 2, the tip of the operating portion 1a of the switch 1 is inside the surface of the panel 2 as shown in the figure, so the operating portion 1a is operated in the recessed window 2a. ..

Example 2. In the first embodiment, the switch 1 is operated by the lever, but it may be used for a push button switch or the like which may malfunction due to contact.

[0011]

[Effect of the device]

 As described above, according to the present invention, the panel to which the switch is attached is provided with a depressed window in which the operation portion of the switch can be operated and the operation portion of the switch is inside the surface of the panel when the switch is attached. Therefore, it is possible to prevent an erroneous operation due to careless contact with the operation section.
