A dust cover 32 is provided on a section of the push rod 3 passing through the base 1. The dust cover 32 is arranged in a corrugated tube structure and has good retractability. One end of the dust cover 32 is clamped in the first mounting groove 121, and the other end is clamped in the second mounting groove 31.
[0044] By setting the mounting convex ring 12, it is convenient to install the push rod 3 on the base 1, and the through hole 11 and the mounting convex ring 12 are integrally formed on the base 1, a first mounting groove 121 is set on the mounting convex ring 12, and a second mounting groove 31 is set on the push rod 3. The push rod 3 exposed to the outside of the base 1 can be enclosed and protected by a retractable dustproof ring, thereby ensuring a good dustproof and waterproof effect.
[0045] Reference Figure 1 and Figure 3-4 The joint between the base 1 and the upper cover 2 is provided with a wire outlet 22 for leading out the internal lead wire, and the wire outlet 22 is filled with a waterproof colloid. In order to further improve the overall sealing of the signal switch, thereby improving the dustproof and waterproof effect, the upper cover 2 is provided with a sealing groove 21 for the base 1 to be embedded on one side, and a waterproof glue layer is provided at the contact surface between the groove wall of the sealing groove 21 and the base 1. In this embodiment, the material of the waterproof colloid and the waterproof glue layer is 704 silica gel.
[0046] Reference Figure 2 and Figure 5-9 , a circuit board 4 and an auxiliary on-off unit 5 are installed in the base 1. The auxiliary on-off unit 5 includes a movable contact frame 51, an on-off brush 52 and a conductive strip 53. The movable contact frame 51 is connected to the end of the push rod 3 extending into the base 1, and the end of the push rod 3 passing through the base 1 is fixedly connected to the trigger 33 by plugging. A guide rib 13 is integrally formed on the inner wall of the base 1, and a guide slot 511 adapted to the guide rib 13 is provided on the back of the movable contact frame 51. The on-off brush 52 is installed on one side of the movable contact frame 51, and the conductive strip 53 is fixed to the second board surface of the circuit board 4; when the trigger 33 is in a natural state, the on-off brush 52 and the conductive strip 53 remain in a disconnected state; when the trigger 33 is in a pressed state, the on-off brush 52 is conductive to one of the sites on the conductive strip 53.
[0047] When the signal switch is used, when the trigger 33 is pressed inward, the trigger 33 drives the push rod 3 and the moving contact frame 51 to move inward together. The on-off brush 52 on the moving contact frame 51 corresponds to the conductive strip 53 on the circuit board 4. During the pressing process, as the on-off brush 52 moves, the auxiliary switch is switched from the open state to the closed state.
[0048] Reference Figure 5 and Fig. 9 To facilitate the installation of the movable contact frame 51 and the push rod 3 , a limit buckle 512 is integrally formed on the back of the movable contact frame 51 , and a limit slot 34 matching the limit buckle 512 is provided on the outer circumference of the push rod 3 .
[0049] Reference Figure 2 and Figure 5 The base 1 is provided with an elastic reset assembly 14, which includes a spring column 141 installed in the base 1 and a compression spring 142 sleeved on the spring column 141. A spring receiving groove 514 is provided at one end of the movable contact frame 51 away from the push rod 3. The other end of the spring column 141 is fixed with a limiting portion 1411. One end of the compression spring 142 abuts against the limiting portion 1411, and the other end is arranged in the spring receiving groove 514. In this way, when the trigger 33 is pressed, the push rod 3 and the movable contact frame 51 are driven to move inward, and the compression spring 142 is compressed to store energy; after the trigger 33 is released, the compression spring 142 releases energy and pushes the trigger 33 to reset, so that the trigger 33 can move and control the signal switch.
[0050] Reference Figure 2 , Figure 6-7 and Fig.10 The base 1 is also provided with a speed regulating unit 6, which includes a linear Hall element 61 and a Hall element trigger assembly.

The mounting protrusion 513 passes through the avoidance hole 41 and is adapted to be connected with the mounting hole 621.
[0052] When using the signal switch, when the trigger 33 is in the natural state, the second magnet 64 is directly opposite to the linear Hall element 61, and the linear Hall element 61 does not output a speed control signal at this time; when the trigger 33 is in the pressed state and is gradually pressed, the movable contact frame 51 is driven to move inward, and the movement of the movable contact frame 51 drives the magnet mounting seat 62 to move, thereby driving the first magnet 63 and the second magnet 64 to move inward, and the distance between the first magnet 63 and the second magnet 64 and the linear Hall element 61 gradually changes, thereby causing the output voltage of the linear Hall element 61 to gradually change, which is convenient for realizing the speed control function. The signal switch does not need to use a brush structure to realize the switch speed control, and does not need to contact the circuit board 4 during the speed control action, thereby reducing the wear of the circuit board 4 and helping to extend the service life of the switch.
[0053] Reference Figure 2 , Figure 8 and Figure 11-12 The signal switch further includes a commutation unit 7, which includes: a commutation drive member that can be toggled; a commutation mounting seat 73 that is slidably arranged in the base 1 along the horizontal direction and is driven by the commutation drive member to move; and a commutation signal output module that is arranged on the commutation mounting seat 73 and cooperates with the circuit board 4. The commutation signal output module includes a commutation brush 74 installed on the commutation mounting seat 73, and two commutation signal strips 75 that are fixed on the second board surface of the circuit board 4 and are arranged at intervals corresponding to the commutation brush 74.

A mounting shaft portion 711 is integrally formed at the bottom of one end of the reversing lever 71. The reversing lever 71 is rotatably mounted on the base 1 through the mounting shaft portion 711. A mounting shaft hole 15 matching the mounting shaft portion 711 is provided at the upper part of one side of the base 1; a plurality of rotation limit protrusions 712 are integrally formed at the eccentric area of the bottom surface of the mounting shaft portion 711, and a rotation limit groove 721 matching the rotation limit protrusion 712 is provided at one end of the reversing limit block 72, which is connected in series with the mounting shaft portion 711 through a self-tapping screw 76 and then rotatably connected to the base 1 respectively. The other end of the reversing limit block 72 is provided with a mounting groove 725, in which a reversing elastic member 722 is installed, and a ball 723 is provided at one end of the reversing elastic member 722 away from the bottom wall of the mounting groove 725, and a plurality of reversing limit grooves 16 are provided on the inner wall of the base 1, one end of the ball 723 is located in the mounting groove 725, and the other end is embedded in one of the reversing limit grooves 16, and when the reversing elastic member 722 is compressed, the ball 723 can move from one of the reversing limit grooves 16 to another reversing limit groove 16.

In this embodiment, two rotation limiting protrusions 712 are provided; the reversing elastic member 722 is a compression spring; and three reversing limiting grooves 16 are provided, corresponding to the three reversing positions of the signal switch.
[0055] When using the signal switch, the function of the reversing lever 71 is to allow the switch to give different reversing signals through its different positions of left, middle and right to control the forward / reverse rotation of the whole machine. The specific operation of reversing is as follows: when the reversing lever 71 is toggled, the reversing limit block 72 is driven to rotate, and the reversing protrusion 731 is installed in the guide arc groove 724 on the reversing limit block 72, while the reversing mounting seat 73 is partially restricted in freedom and can only move left and right. The reversing mounting seat 73 drives the reversing brush 74 to move left and right. The reversing brush 74 corresponds to two commutation signal belts 75 arranged at intervals, one of which is used to output a forward signal and the other outputs a reverse signal. The left and right movement of the reversing brush 74 causes the circuit board 4 to output different signals, which is convenient for controlling the forward / reverse rotation of the whole machine and realizing the reversing function.
