Description

Technical Field

[0001] The invention relates to the field of switches, and in particular to a multi-channel output conversion structure of three-position two-group output switches. Background Art

[0002] When designing a product, a three-position, three-group output switch is often required to provide switch signals to related equipment on the aircraft. The number of switches with such requirements is extremely small. Due to the current 100% localization indicator and the space limitations on the placement of switches on the product, the number of available switches is even smaller. Currently, the most common switch type is a three-position, two-group output switch. In order to meet the three-position, three-group output requirements during product design, it is necessary to improve the design of the three-position, two-group output switch. Our improvements mainly perform logical judgment on the output status of the two-group output switch, thereby giving the third group of outputs of the switch. Summary of the invention

[0005] When the switch body is switched to the first gear position, the first diode and the third diode are turned on, the second diode and the fourth diode are turned off, the first output circuit outputs, and the second output circuit and the third output circuit do not output;

[0006] When the switch body is switched to the second gear position, the first diode and the third diode are cut off, the second diode and the fourth diode are turned on, the second output circuit outputs, and the first output circuit and the third output circuit do not output;

[0007] When the switch body is switched to the third gear, the first diode, the second diode, the third diode and the fourth diode are cut off, the third output circuit outputs, and the first output circuit and the second output circuit do not output.

[0008] Compared with the prior art, the beneficial effects of the present invention are at least that: a commonly used three-position two-group output switch is selected in the switch conversion design. The selected switch has a variety of shapes, a full range of loads, and various installation forms, etc., and can meet the output form of different load requirements. After the multi-channel output conversion design, the three-group output switch can meet the design requirements of various load forms, reduce the burden of switch selection, and solve the human-machine ergonomics interference problem during product layout, etc. BRIEF DESCRIPTION OF THE DRAWINGS
