Description

Technical Field

[0001] The utility model belongs to the field of signal switches, and in particular relates to a double potentiometer signal switch and electric equipment. Background Art

[0002] The structure of the existing signal switch with speed adjustment function according to actual needs is as follows Figure 1 As shown, the switch body 1' is provided with a knob 2', a trigger 3', and a lock button 4'. A travel limit structure is provided between the knob 2' and the trigger 3'. By rotating the knob 2', the maximum working travel S of the trigger 3' can be limited to achieve the purpose of changing the speed V range. Then, the trigger 3' is pressed to make the device work. When the maximum speed is reached, the lock button 4' can be pressed, so that the human hand does not need to keep pressing the button trigger, thereby achieving a labor-saving effect. For example, Figure 2 As shown, turning the knob 2' limits the maximum working stroke of the trigger 3' to S1, and the maximum speed that can be reached by pressing the trigger 3' is the corresponding V1. However, this signal switch has several obvious defects. When the device is operated manually, it is impossible to turn the knob 2' while pressing the trigger. The knob must be turned in advance to set the pressing stroke of the trigger before the trigger can be pressed to work. This operation mode makes it very inconvenient for users in busy work. On the other hand, by adjusting the knob, the working stroke of the trigger is changed to achieve the purpose of changing the speed regulation range. The greater the distance the knob moves, the shorter the working stroke of the trigger. When the user operates the device, once the trigger is pressed, the device will immediately reach a maximum speed limit. This speed change is very rapid, and the user's hand feel experience is very poor, and it may even affect personal safety. Utility Model Content
