Description

Detailed Description of the Invention [Industrial Application Field 1] The present invention eliminates a mechanical rotation mechanism and manually (chestnut) transmits addition and subtraction signals for contact switching to an electronic rotary switch that electrically performs multi-contact switching. Regarding the switch that outputs depending on the operation.

[Prior Art] Conventionally, a rotary switch has a structure in which the rotation of a knob is used to perform multi-contact switching using a mechanical rotating mechanism to open and close circuits. It is used to select any one state from among them, and the following method is used to display the selected state.

For example, in a rotary switch used to change the time axis of an oscilloscope (suspension timing), all selectable sweep cycle information is engraved or printed on the oscilloscope operation surface in one-to-one correspondence with the rotational movement of the manual operation knob.

[Problems to be solved by the invention] As mentioned above, in the conventional rotary switch, information for all selectable states must be engraved or printed in advance on the operating surface of the electrical device. Requires a large footprint. Therefore, if a large number of conventional rotary switches are used in electrical separates that often have to be selected based on the area of the operating surface, such as small multi-functional measuring instruments, the manual operation part will be small and operability will be reduced. Bad,
Moreover, since the displayed information is engraved or printed in small fonts, it has the disadvantage of being difficult for children.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned drawbacks and provide a switch constituting a rotary switch with a large operation surface and easy-to-read status display information.

[Means for Solving the Problems] The present invention provides a switch that manually outputs an increase signal and a subtraction signal for switching contacts to an electronic rotary switch that electrically switches multiple contacts, in which a rotating shaft is used as a fulcrum. an operation panel that swings from side to side as a control panel; a signal generator that is suppressed by the operation panel to generate an addition/stop signal and a subtraction signal for the contact cut; and a signal generator mounted on the front surface of the operation panel to generate necessary data. This switch is characterized in that the display element for switching and displaying is switched to the right.

[Example] Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a longitudinal cross-sectional view of an embodiment of the present invention, and FIG. 1 is a cross-sectional view taken along line A-A' of the switch of the present invention shown in FIG. 2 mounted on an operating panel of an electrical device. . In FIGS. 1 and 2, a manually operated operation plate 4 is supported on the switch body 2 so as to be able to swing left and right about a rotation shaft 7, and signals for addition are provided at both ends of the operation plate 4. An addition contact 5 as a generator and a subtraction contact 6 as a subtraction signal generator are mounted. The structure is such that an addition signal and a subtraction signal are generated by opening and closing contacts 5 and 6, and output to an external terminal 11 via an internal wiring 9.

Further, a display element 3 is installed on the front surface of the operation panel 4, and the display element 3 is connected to an external terminal 11 by an internal wiring 10. As a result, switch operation and status display can be performed simultaneously within the area of the operation panel surface 1 where the switches 2 are mounted. 8 is secured by a fixed spring.

Next, the operation of an electronic rotary switch constructed using the switch S according to the present invention will be explained using FIG.

By manually operating the operation panel 4 for addition, the addition signal generator 5 generates the addition signal a. This addition signal a causes the counting device 12 to perform addition and counting. Similarly, by manual subtraction operation, the subtraction signal generator 6 generates a subtraction signal, which causes the counting device 12 to perform a subtraction count.

Therefore, the counting result of the counting device 12 becomes the position information e of the rotary switch. This position information e specifies whether or not to output the display information of the storage device 13 that stores the display information. The output display information e is then input to the display element 3 and output as visible light information.

Further, the position information e is outputted from the rotary switch by the control circuit 14, and this output functions as a contact point of a conventional rotary switch.

Further, the external control signal q is used for exchanging signals with the outside of the electronic rotary switch, and outputs the internal state of the electronic rotary switch to the outside, or conversely sets the internal state of the electronic rotary switch from the outside.

[Effects of the Invention] As described above, according to the present invention, the area occupied on the operation surface is small, the switch operation is easy, and complex displays can be easily read.

Furthermore, by providing an additional device outside the switch, the function of an electronic rotary switch can be easily realized. Also, by making it an electronic rotary switch, the status can be easily set from the outside, which allows for example automatic measurement. This has the effect that the state selection mechanism of the measuring instrument incorporated in the system can be accommodated in the area occupied by one switch, and the functions of the switch can be expanded.
