Description of the invention: [Technical field of the invention] The present invention relates to a trigger switch device for use in a power supply tool, in particular to a conductive sheet on a trigger button and three power tabs protruding from the conductive sheet. And corresponding three matching tabs are arranged on the control circuit, thereby forming a device capable of controlling two load functions. [Prior Art] • There are many devices that use the trigger button as an electronic circuit switch. For example, the most common power tool is to set a trigger button on the grip of the electric guard, and then cooperate with the design of the control circuit. The user can control the motor that starts the power tool when the trigger is pressed. However, the trigger switch on the electric motor 1 is designed to control only the start of the motor. It is rarely designed to control the opening and closing function of the other load in addition to controlling the start of the motor. As the demand for versatility increases, the power tool has another load function (such as lighting), and the same-trigger button 10 is the one that controls the opening and closing. Because of this, the inventors have new ideas and designs that can achieve the above requirements by simplifying the circuit structure, and in order to avoid duplication with others, the present day is also specifically searched for existing patent databases. After searching, it was found that although there is a pre-report that can control two switch functions by one board machine, after examining the previous case, it is found that the front case is completely different from the structural design of the present invention, and the invention is more mechanical. Structure, easy to implement and manufacture, reduce costs, improve durability and other effects. In order to make your review understand the difference between the previous case and the present invention, the prior case is specifically described. The reference case is the US Patent No. 1269695 9IV, Amendment No. 6,803,683, which has a first and a first extension: a first member and a second member are electrically non-conductive, and the second member is on the second member. The guide is provided with a relay 'and is provided with two guides for the second member, and the point 'the towel' is followed by the switch when the first member is touched by the first member and the second member and the second contact member When the joint is turned on, the second function is turned on. The reference must be added with a relay. The circuit becomes more complicated, the cost of the parts is relatively old, the 7 is not easy to install, the bribe is edited (4), and the "plate" is made of plastic. One member and the second member are easily broken by use', and thus the nature of the citation is considered. SUMMARY OF THE INVENTION The main object of the present invention is to provide a function that can be used to control two loads, and to simplify and structure, and to enhance the financial device (four) trigger device, which includes: - the trigger is electrically conductive on the trigger button a sheet, the conductive sheet is folded and folded into two first and second power strips extending toward the direction of movement of the trigger button, and the conductive sheet and the first, second and third power strips are electrically connected The chip is - body and electrically connected; - (4) circuit, the control weave includes a first-electron circuit and a second electronic circuit that are connected in parallel with each other 'the first electronic circuit rib controls the first-electronic load of the power tool' The electronic circuit is configured to control the operation of the motor of the electric tool, and the control circuit is provided with three conductive materials corresponding to the first power-on piece, the second power-on piece and the third power-on piece of the conductive sheet The first connecting piece, the second connecting piece and the third connecting piece, the first connecting piece and the second connecting piece are corresponding to the first connecting piece and the second connecting piece to form a control The first opening of the first electronic circuit 6
