Why are wireless kinetic energy switches recommended?

In life, wireless switch can be seen everywhere, wireless switch and batteries seem inseparable. However, when using batteries, we will encounter some problems: trouble to change the battery, easy corrosion of the battery in a humid environment, and the battery is very polluting the environment. Did you know that wireless switch does not require batteries.

The working principle of the wireless self-electric switch is to use energy collection technology to convert the trace kinetic energy generated by pressing the switch into electrical energy to form the energy supply for signal transmission, while RF433 RF technology is used to realize the wireless control of the switch on lamps and other equipment. It works as follows:

1, finger press to produce kinetic energy;

2, internal power generation module to collect kinetic energy;

3, kinetic energy into electric energy;

4, the communication module sends a signal, and the wireless receiver controls the device according to the received signal.

The advantages of this self-powered wireless switch are

1, no wiring, no wall chiselling, easy to install: can be placed anywhere or glued directly to the glass, marble, tiles, wood and other flat surfaces, eliminating the need for traditional switches To be planned before the decoration of the switch position, as well as pre-buried switch bottom box, chiselling walls, pre-buried PVC pipes, wearing cables, and other operations, saving time, effort and money;

2、No need for batteries: energy saving and environmentally friendly, as long as the mechanical properties are maintained, it can be used all the time;

3, you can set up a multi-control mode, you can also control a multi-control, can replace the ordinary traditional dual-control switch, change the placement point at will.

So the wireless control "ceiling" is self-generated switch, we should have no objection, right?

In addition, the self-generating wireless switch also has its limitations: the energy generated is relatively small, because the energy of pressing the switch itself is relatively small.

For the self-powered switch to be able to drive the control module with limited power, all other devices in its system must be low-power, including the control module and the RF module.

So it should not be used in addition to high power equipment control, which can easily cause control failure.
