In this case, the transmission output can be performed only by pressing the simple operation button 21 to activate the simple operation switch terminal 24, or by pressing the erroneous operation prevention buttons 22, 22 to activate the erroneous operation prevention switch terminals 25, 25. When the simple operation switch terminal 24 and the erroneous operation prevention switch terminals 25, 25 are connected in parallel as described above, the simple operation is performed with the switch body 2 covered with the cover 3 as shown in FIGS. It is not necessary that the button 21 or the erroneous operation prevention buttons 22, 22 be configured to be pressed by the cover 3.

The setting of the operation by the simple operation switch terminal 24 or the operation by the erroneous operation prevention switch terminals 25, 25 is limited to the setting made by the circuit configuration of the switch body 2 as described above. Instead, the switching may be performed by a changeover switch (not shown) separately provided in the switch body 2. Also, there are three switch terminals 24, 2
Any one or more of the switches 5 and 25 are set, and a control microcomputer that performs transmission output when the set switch terminals 24, 25 and 25 are operated is incorporated in the circuit configuration of the switch body 2. It may be something. When such a control microcomputer is incorporated, as shown in FIG. 3 or FIG. 6, transmission output is performed by pressing both of the erroneous operation prevention buttons 22, 22 with the erroneous operation prevention switch 1 b configured. In addition to the above, transmission output can be performed by pressing one of the erroneous operation prevention buttons 22, 22, and transmission output can be performed by pressing one specified erroneous operation prevention button 22. However, even if the other unspecified erroneous operation prevention button 23 is pressed, transmission output may not be performed.

The total number of 22 is not particularly limited to three, and may be one, two, or four or more. In the two cases, when only one of the buttons is exposed by the cover 3 in combination with a changeover switch (not shown) separately provided on the switch body 2 described above, the exposed button is pressed. When the cover 3 is not provided, or when all the two buttons are exposed by the cover 3, an erroneous operation prevention switch 1b that is operated by operating the two buttons can be configured. Can be configured.

As shown in FIG. 8, one button 6
The button switch 12 may be configured so that only one button 61 is exposed regardless of the direction in which the cover 7 is attached to the switch main body 6 having the switch 1. However, in this case, it is not possible to switch between the simple operation state and the erroneous operation prevention state with the number of exposed buttons, so that the circuit configuration changes the button input reception time depending on the cover mounting direction, In the simple operation state, the input reception time may be short, and in the erroneous operation prevention state, the input reception time may be long.

In the case of the button switch 12 shown in FIG. 8, when the cover 7 is mounted from one of the directions A, as shown in FIG. The changeover switch 62 can be prevented from being input when the cover 7 is mounted from another direction B when the input is made by the provided projection piece 71. Thus, the input reception time can be changed by attaching the cover 7 to the switch body 6 from different directions A and B.

While the embodiment as a switch for reporting a nurse call or the like has been described above, the embodiment of a push button switch used for other purposes will be described.

That is, the button 42 that is always exposed is a power button, and the button 41 that is exposed when the cover 5 is mounted from one direction A is a control button for cooling and dehumidification, and is exposed when the cover 5 is mounted from the other direction B. The button 43 can be used as a control button for heating or humidification, and can be used by changing the mounting directions A and B between summer and winter.

In the case of the button switch 2 shown in FIG. 8, even if the cover 7 is mounted in any direction A or B, since the exposed button 61 is one, the transmitted signal is usually the same. Would. Therefore, as described above, when the input of the changeover switch 62 is switched according to the mounting direction of the cover, different signals can be transmitted even when the same button 61 is pressed.

Further, in the present embodiment, the cover 3 is mounted on the switch body 2 from different directions A and B.
The mounting may be reversed from one side of the switch body 2 (for example, the direction of the arrow A in FIG. 1) by inverting itself. In this case, even when the switch body 2 is not of the wireless type and has a wire for transmission output (not shown), the wire (not shown) may be routed to the side where the cover 3 is not attached. Can be.

Depending on the difference in the mounting / removing direction, the operation switches of a plurality of devices can be shared, and the proper use of the switches can be ensured. In addition, since signals to be transmitted are limited depending on the difference in the direction in which the cover is attached or detached, it is possible to prevent erroneous operation due to an erroneous signal even when operating a single device.

According to the second aspect of the present invention, a simple operation switch operated by a single button operation and an erroneous operation prevention switch operated by a plurality of button operations are provided by attaching and detaching a cover to and from the switch body. Since both can be used, a simple operation switch giving priority to simple operability or an erroneous operation prevention switch giving priority to erroneous operation prevention can be provided according to the use environment. In addition, since the button switches having the opposite functions can be used in this way, it is not necessary to produce both button switches, and the production and sale can be performed efficiently.

According to the third aspect of the present invention,
A simple operation switch that gives priority to simple operability that operates with one button operation and an erroneous operation prevention switch that gives priority to erroneous operation prevention that operates with multiple button operations can be used as well as an erroneous operation prevention switch. In the state, it is possible to selectively use an erroneous operation prevention mode that operates by operating all the buttons of the plurality of exposed buttons and a simple operation mode that operates by operating any one of the buttons, thereby further expanding the variation of the use environment. it can.

Further, according to the present invention described in claim 4,
By imposing a requirement that at least two or more of the plurality of exposed buttons are pressed substantially simultaneously, erroneous operation can be reliably prevented, and solid erroneous operation prevention can be obtained.

Further, according to the present invention described in claim 5,
When switching the cover on and off the switch body, there are cumbersome adjustments and complicated circuits, such as having to select the exposed button and the unexposed button and react only to the exposed button so that the switch operates. Since it is not necessary, the configuration of the switch body can be simplified and the configuration can be made inexpensively, and the simple operation switch and the erroneous operation prevention switch can be easily switched, so that the usability is improved.

According to the sixth aspect of the present invention, by attaching / detaching the cover to / from the switch body, the simple operation switch having a short input acceptance time and the erroneous operation prevention switch having a long input acceptance time can be used. Depending on the use environment, a simple operation switch giving priority to simple operability or an erroneous operation prevention switch giving priority to erroneous operation prevention can be used. In addition, since the button switches having the opposite functions can be used in this way, it is not necessary to produce both button switches, and the production and sale can be performed efficiently.
