Chu is fully described by, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole realities
Apply example.The component of the utility model embodiment being usually described and illustrated herein in the accompanying drawings can be come with a variety of different configurations
Arrangement and design.Therefore, the detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit below
The range of claimed invention, but it is merely representative of the selected embodiment of the utility model.Based on the utility model
Embodiment, those skilled in the art's every other embodiment obtained without making creative work, all
Belong to the range of the utility model protection.
Fig. 1-3 is please referred to, a kind of low-consumption wireless touch key-press switch based on dim light charging is provided in the present embodiment,
Including wireless switching transmission unit and wireless switching receiving unit, wireless switching transmission unit includes touch key-press module, first
Power supply system and wireless transmitter module, wireless switching receiving unit include the second power supply system, wireless receiving module and load control
System processed.In the present embodiment only by taking lamps and lanterns as an example, therefore load control system is lamp control system.Second power supply system is wireless
Receiving module and lamp control system provide power supply, and second source can be realized directly using capacity voltage dropping circuit.
First power supply system provides electric energy for touch key-press module, wireless transmitter module.First power supply system includes power supply
Battery and dim light charging circuit, supplying cell and dim light charging circuit are in parallel, to realize that same time supplying cell and dim light fill
One of electric both circuits are that touch key-press module and wireless transmitter module are powered.
