Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] like figure 1 and figure 2 As shown, the power self-contained multi-button switch device of the embodiment of the present invention includes a plurality of switch buttons 10 , a plurality of signal trigger modules 20 , a signal processing circuit board 30 , a drive module 40 and a power generation module 50 .

[0020] A plurality of signal trigger modules 20, located below the switch buttons 10, are arranged in one-to-one correspondence with the switch buttons 10. When any switch button 10 is pressed, the corresponding signal trigger module 20 generates a trigger signal; in one embodiment ...

Abstract

The invention discloses a self-power-supplying multi-key switch device including a plurality of switch keys, a drive module, a plurality of signal triggering module and a power generation module. Thedrive module is disposed below the switch keys and is connected with the power generation module. The signal triggering modules are disposed below the switch keys and are in one-to-one correspondencearrangement with the switch keys. The switch keys share the power generation module. When any one among the switch keys is pressed, the drive module drives the power generation module to generate power. The signal triggering module corresponding to said switch module generates a triggering signal. According to the invention, the corresponding signal triggering module generates triggering signals after an arbitrary switch key is pressed, at the same time, the power generation module is driven to generate power so as to supply power for the whole switch device. Small size and low weight of the switch device are realized and cost is also saved.

Description

technical field [0001] The invention relates to a switch, in particular to a power supply self-contained multi-button switch device. Background technique [0002] Most of the existing passive switches are powered by a built-in dry battery or a built-in power generation module. The passive switch with a built-in power generation module is popular with users because of its lightness, energy saving and environmental protection. When the user presses the switch button, the power generation module generates electricity. Provide power to the control circuit corresponding to the button, send the control signal corresponding to the button, and control the electronic product corresponding to the switch. For a switch with a plurality of keys, power generation modules corresponding to the number of keys are required to provide electric energy for it, but this will lead to the problem of complicated and bulky switch structure. Contents of the invention [0003] Aiming at the above te...
