The slider 8 is in the first position, in which the brushes 9 on the slider 8 and the circuit board 10 connected to the base 7 are in a disconnected state.
In the switch housing 1, the elastic member 12 connected to the movable frame 6 is in a state of being inclined downward.
As shown in fig. 10, when the trigger 2 is pressed, the trigger 2 drives the movable frame 6 to move downward to the first intermediate position. During this actuation of the trigger 2, the elastic element 12 of the mobile frame 6 is gradually compressed and, when the mobile frame 6 reaches the first intermediate position, the elastic element 12 is in a horizontal condition, while the slider 8 is still in the first position.
As shown in fig. 11, to continue to press the trigger 2 on the basis of fig. 10, the trigger 2 drives the movable frame 6 to continue to move down to the execution position at the lowest end. In the process of pressing the trigger 2, the elastic piece 12 connected with the movable frame 6 inclines upwards and releases elastic force, and in the process of releasing the elastic piece 12, the elastic piece 12 drives the bridge plate 11 to turn upwards around the second connecting shaft 18, and the bridge plate 11 drives the sliding block 8 to move upwards, so that the electric brush 9 on the sliding block 8 is communicated with the circuit board 10 on the base 7.

When the movable frame 6 continues to move upwards through the second middle position, the elastic piece 12 tilts downwards and releases elastic force to enable the sliding block 8 to move downwards, and the electric brush 9 on the sliding block 8 is disconnected with the circuit board 10 on the base 7.
Since the movement of the slider 8 is driven by the abrupt release of the elastic force of the elastic member 12, the brush 9 and the circuit board 10 can be more rapidly turned on and off, thereby improving the service life of the circuit board 10.
As shown in fig. 12, a schematic view of the terminal groove 4 at the lower end of the housing 1 is shown.

As shown in fig. 2, a clip groove 30 is provided on one side of the base 7, and the clip groove 30 is used for connecting the circuit board 10. Two signal conduction are provided ON the circuit board 10, namely one of the ON/OFF signals and the other is a slide resistance signal; when the ON/OFF signal is ON and the duty ratio of the slide resistance signal reaches a certain value, the equipment can work normally. ON the contrary, when the ON/OFF signal is damaged or when the duty ratio of the slide resistance signal does not reach a certain value, the equipment cannot work normally, and the safety is high.
Principle of operation
When the trigger 2 is pressed, the movable frame 6 connected with the trigger 2 moves downwards, the biasing spring connected with the movable frame 6 moves downwards, when the movable frame 6 passes through the first intermediate position, the biasing spring generates a jump to release energy, the biasing spring drives the bridge plate 11 to rotate upwards, the bridge plate 11 pivots through the second connecting shaft 18, the sliding block 8 connected with the bridge plate 11 through the first connecting shaft 16 and the electric brush 9 arranged on the sliding block also move upwards, and the electric brush 9 is communicated with the circuit board 10.
