In the daily life, for controlling electrical apparatus or electronic devices on and off, a switch assembly is usually provided to be coupled with electrical apparatus and the electronic devices, so that a user can operate a switch button connected to the switch assembly to switch-control electrical apparatus and the electronic devices “On” and “Off”.
Basing on above description, a conventional embodiment is further disclosed to illustrate the prior arts as mentioned above. Please refer to
The switch cell 2 comprises a main body 21, a switch button 22 and a switch circuit 23. The switch button 22 is connected to the main body 21; the switch circuit 23 is located within the main body 21, and usually mechanically connected with the switch button 22 via a flexible plate and a spring. Meanwhile, one end of the switch circuit 23 is usually connected to a power source (not shown) via a power-in wire Li, and the other end of the switch circuit 23 is usually connected to a first loading (not shown) via a power-out wire Lo; wherein the switch circuit 23 is provided with two contacts P1 and P1′, and the first loading can be electrical apparatus or the electronic devices as mentioned.
Similarly, the switch cell 3 comprises a main body 31, a switch button 32 and a switch circuit 33. The switch button 32 is connected to the main body 31; the switch circuit 33 is located within the main body 31, and usually mechanically connected with the switch button 32 via a flexible plate and a spring. Meanwhile, one end of the switch circuit 33 is usually connected to a power source (not shown) via a power-in wire Li′, and the other end of the switch circuit 33 is usually connected to a second loading (not shown) via a power-out wire Lo′; wherein the switch circuit 33 is provided with two contacts P2 and P2′, and the second loading can be electrical apparatus or the electronic devices as mentioned.
When the user need to make the first loading under a loading condition, i.e., when the user need to operate electrical apparatus or electronic devices, he can switch the switch button 22 on, and then the contact P1 is connected to the contact P1′ to form a closed circuit (not shown), so that the power source can supply a nominal electricity to electrical apparatus or the electronic devices to make the electrical apparatus or the electronic devices under the loading condition.
On the contrary, when the user need to make the second loading under an unloading condition, i.e., when the user need to turn off electrical apparatus or electronic devices, he can switch the switch button 32 off, and then the contact P2 is electrically separated from the contact P2′ to form an open circuit (not shown), so that the power source interrupts supply the nominal electricity to electrical apparatus or the electronic devices to make the electrical apparatus or the electronic devices under the unloading condition.
From the prior arts as disclosed above, obviously, it still needs to switch control the switch circuit 23 or 33 “On” and “Off” via manual operation. However, under the consideration of convenience, or under some operation requirements, it is necessary to switch control the switch circuit 23 or 33 on or off. Thus, it is obvious that the conventional switch cell 2 or 3 cannot meet the requirements of wireless control.
Although that many different wireless switch assemblies are presented in the market after the absence of the conventional switch assembly 100; while, there do still exist three major disadvantages. The first major disadvantage is that the wireless switch assemblies are not spatially compatible to the existed frame 1 and the covering board 4, so that the wireless switch assemblies cannot directly assembled to the existed frame 1 and the covering board 4 to replace the switch cells 3 and 4. The second major disadvantage is that the wireless switch assembly is controlled by a wireless analog signal, so that the wireless switch assembly is easier to be blind triggered by external wireless interference signals. The third major disadvantage is that the wireless switch module is not able to be controlled to switch “On” or “Off” when the strength of the wireless digital control signal is insufficient to make it be effectively received by the wireless switch module. It is more important that the two disadvantages are still neither overcome, so that the wireless switch assembly has not been widely used yet.
Due to that there are three problems existing in the prior arts, such as the switch assembly cannot meet the requirements of wireless control, the wireless switch assembly cannot spatially compatible to the existed frame and the covering board, and the wireless switch assembly is easier to be blind triggered, the primary objective of the present invention provides a wireless switch module, which can be switch-controlled either via a mechanical means, or via a wireless digital control signal. Moreover, in spatial, the wireless switch module is compatible to the existed frame and the covering board, so as to directly replace the switch cell(s).
The secondary objective of the present invention provides a wireless switch module comprising a micro control circuit, so as to receive and analyze a wireless digital control signal to accordingly switch-control the switch circuit(s) within the wireless switch module “On” and “Off”.
Another objective of the present invention provides a wireless switch module comprising a wireless signal transceiver. When a wireless digital control signal cannot be effectively received by a wireless module located in a remote end, the wireless digital control signal can be received and transmitted by other wireless switch modules, so as to indirectly transmit the wireless digital control signal to the wireless switch module located in the remote end.
Means of the present invention for solving the problems as mentioned above provides a wireless switch module being fitted with a frame and a covering board, so as to form a wireless switch assembly. The wireless switch module comprises at least one switch cell and a control unit. The switch cell comprises a switch circuit, a switch button and a relay, and the control unit comprises a micro control circuit coupling with the relay. Within the wireless switch module, the switch button is applied to switch-control the switch circuit “On” and “Off”; furthermore, the micro control circuit is also applied to switch-control the switch circuit “On” and “Off” via the relay after receiving and analyzing a wireless digital control signal. In the preferred embodiment of the present invention, the micro control circuit further comprises a wireless signal transceiver.
Comparing with the conventional switch assembly, the wireless switch modules as provided in the present invention can be switch-controlled both via the switch button(s) and the wireless digital control signal; therefore, the present invention can meet the requirement of wireless control.
Comparing with the existed wireless switch assembly, the wireless switch modules as provided in the present invention can be directly connected to the existed frame and the covering board, and can be further electrically connected to a power source and at least one loading via at least one power-in wire and power-out wire. Therefore, both in spatial and electrical, the wireless switch module is compatible to the existed frame, covering board, power-in wire(s), power-out wire(s), so that the wireless switch module can directly replace the conventional switch cell(s).
In the present invention, except for receiving the wireless digital control signal, it is still necessary for the wireless switch module to execute a digital analysis to the wireless digital control signal, and then switch-control the switch circuit “On” and “Off” in accordance with the analysis result. Thus, the wireless switch module of the present invention can effectively prevent from being blind triggered by external wireless interference signals.
Nevertheless, in the preferred embodiment of the present invention, the micro control circuit further comprises a wireless signal transceiver. When a wireless digital control signal cannot be effectively received by a wireless module located in a remote end, the wireless digital control signal can be received and transmitted by other wireless switch modules, so as to indirectly transmit the wireless digital control signal to the wireless switch module located in the remote end. Therefore, it is obviously that the art of the present invention can control the wireless switch module located in the remote end via the indirectly transmission method.
The devices, characteristics, and the preferred embodiment of this invention are described with relative figures as follows.
The structure and the technical means adopted by the present invention to achieve the above and other objects can be best understood by referring to the following detailed description of the preferred embodiments and the accompanying drawings, wherein
Due to that the wireless switch module as provided in accordance with the present invention can be widely applied to control the switch circuit “On” and “Off”, and further directly replace the conventional switch cell(s), the combined applications are too numerous to be enumerated and described, so that on the basis of the structure, only a preferred embodiment is disclosed as follows for representation.

As shown in
When the analysis result implies that switch on the switch circuit 54, a switch-on signal S2 can be transmitted to the relay 53, and the switch circuit 54 can be switched on via the relay 53, so that the power source can supply a nominal electricity to the loading 300 to make the loading 300 under a loading condition.
