     BACKGROUND 
     Technical Field 
     This disclosure relates to a switch device and the controlling method of the switch device, in particular, to an electrical dual control switch device and the controlling method thereof. 
     Related Art 
     Switch is an electrical element for opening the circuit, stopping the current or redirecting the current to other circuit. Therefore, switch is one of the commonly used electrical devices nowadays. While the switch is set on the ON status, the current could pass through and while the switch is set on the OFF status, the circuit will be set as an open circuit that block the current. 
     At first, most of the switches applied in the electrical device are one way switch (single control switch). The structure of the one way switch is relatively simple, and the characteristic of one way switch is that one switch could only control one or one set of electrical device thus make one way switch is could be control and design in a straightforward manner. With the advantage of simply use and easy to set up, one way switch is widely used in housewares, companies and for particular electric need. 
       FIG. 1  is a perspective view of the conventional dual switch device. The conventional dual switch device  10  includes a first switch  11 , a second switch  13 , an AC power device  15  and a loading device  17 . The first switch  11  has a first switcher  111 , a first junction  113  and a second junction  115 . The second switch  13  has a second switcher  131 , a third junction  133  and a fourth junction  135 . The first junction  113  is electrically connects with the third junction  133 , and the second junction  115  is electrically connects with the fourth junction. One end of the switcher  111  is electrically connects with the AC power device  15 , and the other end of the AC power device  15  is connected to the loading device  17 . At the other end of the loading device  17  connects the second switcher  131 . The loading device  17  could be any of the below electric device, such as lamp, exhaust fan or heater. 
     The switcher  111  of the first switch  11  could be switched to connect with the first junction  113  or the second junction  115 . The second switcher  131  of the second switch  13  could be switched to connect with the third junction  133  or the fourth junction  135 . 
     While the first switcher  11  is connected with the first junction  113 , and the second switcher  131  is connected with the third junction  133 , the current could be driven through the circuit. That is, the power from the AC power device  15  could drive through the first switch  11 , the second switch  13  to the loading device  17 . The loading device  17  is then activated. When the first switcher  111  connects with the second junction  115 , the second switcher  131  connects with the fourth junction  135 ; the current could also drive through the circuit and activate the loading device  17 . 
     When the first switcher  111  connects with the first junction  113 , the second switcher  131  connects with the fourth junction  135 , the circuit between the first switch  11  and the second switch  13  is opened. The current will be interrupted and the loading device  17  therefore will be shut down. When the first switcher  111  connects with the first junction  113 , the second switcher  131  connects with the third junction  133 , the circuit between the first switch  11  and the second switch  13  is also regarded as open. Therefore, the loading device  17  will be shutoff. By controlling the first switch  11  and the second switch  13 , the user could control the particular loading device  17  at different position. 
     There are still some limitations and improvement to be made for conventional dual electrical switch device, for instance, the loading device could not be remotely control, the usage of the power could not be calculated, there is no design for protecting against overload, and the conventional dual electrical switch device might not capable to work with touch device or sets a timer for automatically shut down the power, etc.
