DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a switch cover, and particularly to a structure of a switch cover in which a plurality of switches are installed closely.

[Prior Art] A conventional switch cover is shown in FIG. A base 6 and a switch 4 are installed on the installation surface 10. The switch guard member 2 is held in the holding portion 66 of the base 6 by a pin 2P. The switch guard member 2 can be opened in the direction indicated by the arrow 100 around this pin 2P.

The switch guard member 2 protects the switch 4 and prevents the switch 4 from malfunctioning. The switch guard member 2 is provided so as to cover the switch 4, so that external pressure is not transmitted to the switch 4.

That is, by providing the switch guard member 2, even if an accidental contact occurs from the outside, the switch 4 will not react to this press. and,
When operating the switch 4, remove the switch guard member 2.
100 in the direction shown by the arrow 100 and press the switch 4. Note that if the switch guard member 2 is provided, the display section 4H of the switch 4 and the like can be protected from damage.

Furthermore, if a plurality of switches are installed relatively close to each other, a wrong switch may cause a different switch to be activated than the desired switch.

If a switch guard member 2 is provided, it is necessary to open this switch guard member 2 when operating the switch. Therefore, visual confirmation is always required, which can prevent malfunctions due to incorrect presses.

[Problems to be Solved by the Invention] However, the conventional switch cover described above has the following problems.

When installing switches, multiple switch groups may be installed densely in rows and columns. In such a case, in order to provide a switch cover for each switch, a holding part 66 between the base 6 and the switch guard member 2 is required (14th
(see figure). That is, in order to provide this holding portion 66, it is necessary to arrange a plurality of switches with spaces between each switch. Therefore, there is a problem in that a plurality of switches cannot be arranged closely together, and a large area is required to install the switch group.

Further, a connecting mechanism such as a bin 2P in the holding portion 66 is required for each switch (see FIG. 14). For this reason, the mechanism becomes complicated and the manufacturing cost increases.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a switch cover that reduces the installation area by installing a plurality of switches closely together, and also simplifies the mechanism and reduces manufacturing costs.

[Means for Solving the Problems] The switch cover according to claim 1 is a switch card member positioned so as to cover a group of switches in which a plurality of switches are densely installed on an installation surface, the switch cover comprising one or more switches. The present invention is characterized by comprising: a switch guard member made of divided guard members; and a holding member that holds a portion of each divided guard member and is fixed to the installation surface.

The switch cover according to claim 2 is a switch guard member positioned to cover a plurality of switch groups each having a switch operating section fixed to a switch main body protruding from an installation surface, the switch cover comprising one or more divided guards. A switch cover comprising: a switch guard member comprising a switch guard member; a holding member having a holding mechanism for holding each part of each divided guard member; and a holding member having a holding surface having a protrusion that fits into a switch body. The holding member is fixed to the installation surface by inserting the protrusion holding surface between the installation surface and the back surface of the switch operating section and fitting the projection to the switch body.

The switch cover according to claim 3 is the switch cover according to claim 1 or 2, characterized in that the switch guard member is positioned to cover a plurality of switch groups.

[Function] The switch cover according to the first aspect covers a switch guard member made of one or more divided guard members or a plurality of switches.

Therefore, there is no need to provide connection parts between the holding member and the switch guard member depending on the number of switches.

In the switch cover according to a second aspect of the present invention, the holding member is fixed to the installation surface by inserting the protrusion holding surface between the installation surface and the back surface of the switch operating section and fitting the projection into the switch body.

Therefore, the switch cover can be attached even after the switch is installed on the installation surface.

In the switch cover according to a third aspect of the present invention, the switch guard member is positioned to cover the plurality of switch groups.

Therefore, there is no need to provide a switch cover for each switch group.

[Example] An embodiment of the present invention will be described based on the drawings.

In the embodiment described below, a switch cover for the switch group 4 as shown in FIG. 13 will be described. The switch group 4 includes switches (A) in which four switch rows are arranged in the horizontal direction 130 and two rows are provided in the vertical direction 132;

The elastic member 8E is connected to the insertion base 8, and is made of resin or the like and has elasticity. When the switch card member 200 is opened in the direction indicated by the arrow 100 (see the first diagram), the elastic member 8E is pushed up in the direction indicated by the arrow 110. And the switch guard member 20
0 is located in the state shown in FIG. 8B, the elastic member 8E
returns to its original state and maintains the position of the switch guard member 200.

Since the switch guard member 200 is held open, the switch can be easily operated.

The switch guard member can also be composed of two or more divided guard members. Dividing the switch guard member is particularly useful when a large number of switches are installed closely together. The mode of division is shown below. Note that the divided guard member can also be provided with the mechanisms shown in FIGS. 7, 8A, and 8B.

Fig. 2 shows the switch guard member divided vertically. The switch guard member 220 is a divided guard member 2
