## Abstract

A wireless switch is provided. The wireless switch comprises a mechanical switch, an electronic switch module, a charger module, a power storage module, and a wireless control module. The electronic switch module is connected to the mechanical switch in parallel. When one of the mechanical switch and the electronic switch module is turned on, the power storage module is charged through the charger module.

## Claims

### Claim 1

A wireless switch, comprising
a mechanical switch, the mechanical switch comprising a power switch, the power switch being connected to a hot wire;
an electronic switch module, the electronic switch module being connected to the hot wire, the electronic switch module being connected to the mechanical switch in parallel;
a charger module, the charger module being connected to the mechanical switch and the electronic switch module;
a power storage module, the power storage module being connected to the charger module; and
a wireless control module, the wireless control module being connected to the power storage module, the wireless control module comprising a micro controller unit;
wherein when an energy level stored in the power storage module is lower than a lower limit level, the micro controller unit turns on the electronic switch module.

### Claim 2 (depends on 1)

The wireless switch of claim 1, wherein when the energy level stored in the power storage module is higher than the lower limit level, the power storage module is capable of supplying electrical power to the wireless control module.

### Claim 3 (depends on 1)

The wireless switch of claim 1, wherein the wireless control module comprises a memory for storing power data of the power storage module, and the power data comprises a value of electrical energy stored in the power storage module.

### Claim 4 (depends on 1)

The wireless switch of claim 1, wherein the electronic switch module is a first electronic switch module, the wireless control module further comprise a second electronic switch module, the second electronic switch module is connected between the hot wire and the wireless control module, and when the second electronic switch module is turned on, the wireless control module uses electrical power from the second electronic switch module, rather than using electrical power from the power storage module.

### Claim 5 (depends on 4)

The wireless switch of claim 4, wherein when the energy level stored in the power storage module is lower than a lower limit level, the first electronic switch module and the second electronic switch module are turned on concurrently.

### Claim 6 (depends on 1)
