In addition, the switch 20 according to the embodiment of the present invention can accumulate two electrical signals when the switch 20 moves in the same moving direction relative to the casing 10 to ensure that the power is sufficient to drive the corresponding device to operate. For example, it is assumed that the wireless communication module 50 needs a voltage of 1 volt to be activated, and the power generating element 32 can generate an electrical signal of 0.5 volts each time the trigger shrapnel 31 is triggered.

In some embodiments, the signal transmission range of the above-mentioned wireless communication module 50 is determined according to the hardware type or the signal transmission method. Specifically, the wireless communication module 50 can establish a short-distance or long-distance communication connection to transmit data, for example, the wireless communication module 50 can be a Bluetooth module (Bluetooth), a Wifi module, a wireless local area network (Wireless Local Area Network) Networks, WLAN) modules, 3G/4G modules, Near Field Communication (NFC) or Low Power Wide Area Network (LPWAN) modules, etc., which are not limited in the present invention .

4 and 5 , when the switch 20 is moved between the first trigger position and the second trigger position, the trigger spring 31 has a movable distance D, for example, the movable distance D may refer to the above trigger spring 31 The shortest distance between the abutting position and the compressed position. In this embodiment, the thickness T of the guiding protrusion 41 of the movable seat 40 is greater than or equal to the movable distance D of the triggering elastic piece 31 (for example, the thickness T of the guiding protrusion 41 is 1 mm, and the movable distance D of the triggering elastic piece 31 is 1 mm). 0.8mm), so that when the switch 20 moves from the initial position to the first trigger position, the movable seat 40 can move 1mm toward the trigger spring 31 to ensure that the trigger spring 31 can move the above movable distance D and smoothly trigger the generator 32 to generate the telecommunication No.

As shown in FIG. 4 and FIG. 5 , in one embodiment, an elastic member 25 is further provided between the linking member 21 of the switch 20 and the housing 10 , and the elastic member 25 abuts between the linking member 21 and the housing 10 . For example, the elastic member 25 can be a spring, but not limited thereto. Thereby, when the switch 20 is pressed and moved from the initial position to the first trigger position and the second trigger position in sequence in the same moving direction (as indicated by arrow L1 ), the compressible elastic member 25 accumulates elastic force. When the switch 20 is released, the elastic member 25 can push the linking member 21 through the accumulated elastic force, so that the switch 20 moves from the second trigger position relative to the housing 10 in a return direction opposite to the moving direction to the first trigger position in sequence. and return to the original position for the next operation by the user.

On the other hand, when the switch 20 moves from the second trigger position to the first trigger position, during the movement process, the pressing protrusion 22 on the linkage member 21 will move to the top 413 along the second side surface 412 of the guiding protrusion 41 . , presses the movable seat 40 to drive the trigger shrapnel 31 to move away from the switch 20 , so that the trigger shrapnel 31 accumulates elastic force and triggers the generator 32 to generate a third electrical signal (ie, an instantaneous pulse current). When the switch 20 is moved from the first trigger position to the initial position, during the movement, the pressing protrusion 22 on the linking member 21 will move from the top 413 of the guiding protrusion 41 along the first side surface 411 , so that the switch 20 is moved. When the movable seat 40 is released, the trigger shrapnel 31 moves toward the switch 20 through the accumulated elastic force and pushes against the side of the movable seat 40 away from the linkage 21 , so that the trigger shrapnel 31 moves toward the switch 20 to trigger the generator 32 A fourth electrical signal is generated (ie, an instantaneous pulse current is generated). In this way, through the arrangement of the elastic member 25, two electrical signals (ie, the third electrical signal and the fourth electrical signal) can be accumulated during the release process of the switch 20, so as to further ensure that the power is sufficient to drive the corresponding device to operate or be able to operate. For use with other electronic components.

At the top 413 , the movable seat 40 is pressed and drives the trigger spring 31 to move away from the switch 20 . The trigger spring 31 accumulates elastic force and triggers the generator 32 to generate a first electrical signal. When the switch 20 is continuously pressed and moves in the same moving direction (the direction indicated by the arrow L1 in FIG. 5 ), the pressing protrusion 22 moves from the top 413 of the guiding protrusion 41 along the second side surface 412 , causing the movable seat 40 to move. After being released, the triggering elastic piece 31 moves toward the direction close to the switch 20 through the accumulated elastic force and pushes against the side of the movable seat 40 away from the linkage 21, so that the triggering elastic piece 31 moves back from the pressed position to the abutting position, and triggers the generator. 32 generates a second electrical signal. If the control end 26 of the switch 20 is continuously pressed again, the switch 20 can continue to move in the same moving direction (the direction indicated by the arrow L1 in FIG. 5 ), so as to pass through the other pressing protrusion 22 ′ and the guiding protrusion The actuation of 41 can drive the movable seat 40 and the trigger shrapnel 31 to act again, and the trigger generator 32 further accumulates two electrical signals, so that the switch 20 can accumulate four electrical signals in one complete pressing stroke, which ensures that the power is sufficient to drive The corresponding device operates.
