When the intelligent toggle switch works, the switch has a three-position on-off relationship of left, middle and right, and the principle is as follows: when the handle rod 4 is pulled to the left position, the tail end of the handle rod 4 is fixed with the guide post 5 to swing rightward, the guide post 5 slides along the right side of the V-shaped touch plate 6, and the right side of the V-shaped touch plate 6 moves downward due to the lever principle, so that an upper contact 7 arranged on the right side of the V-shaped touch plate 6 is contacted with a lower contact 8 on the shell 10, and the contact conduction on the right side of the switch is realized. When the handle rod 4 is pulled to the right position, the structure of the V-shaped touch plate 6 and the upper and lower contacts 8 on the left side are in symmetrical relation with the right side, so that the principle is the same as that described above, and the conduction of the contacts on the left side of the switch is realized. When the switch is in the 'middle' position, the handle rod 4 is limited by the left side sequence return spring 3 and the right side sequence return spring 3 and is in the neutral position, so that the handle rod 4 is not stressed and is in the neutral holding state, and all contacts in the 'middle' position of the switch are disconnected.
Example two
Based on the first example, the switch has the functions of right and left position in-place self-locking, and the principle is as follows: when the handle lever 4 is pulled to the left position, the swing lock block 18 forms a hinged structure with the handle lever 4 through the hinge pin 17, since the shaft of the swing lock block 18 is in the circular arc track of the housing 10, the swing lock block 18 on the right side moves along the circular arc track along with the rightward swing of the handle lever 4 and enters a designated position, which is a pressing mechanism formed by the compression spring 15, the sleeve 16, the left conical press block 13 and the right conical press block 14, as shown in fig. 3 below, when the swing lock block 18 moves to the intermediate position of the left conical press block 13 and the right conical press block 14, the conical press block is pressed by the front end head of the right conical press block 14 at this time, the compression spring 15 is retracted after being pressed, the middle distance between the left conical pressing block 13 and the right conical pressing block 14 is increased, the head of the swing locking block 18 enters the space between the conical surfaces of the left conical pressing block 14 and the right conical pressing block 14, the structure of the swing locking block 18 is that the head is large, the middle is small, and the rear end is large, as shown in fig. 3, when the head enters, the middle part is small, the pressure born by the compression spring 15 is reduced, the middle distance between the left conical pressing block 13 and the right conical pressing block 14 is reduced, the distance is equal to the size of the head of the swing locking block 18, the middle part of the swing locking block 18 is smaller than the head of the swing locking block 18, and the swing locking block 18 is limited in the extrusion mechanism, so that the in-place self-locking function of the switch plate to the left position is realized as shown in fig. 4. When the handle rod 4 is pulled to the right position, the principle is the same as that described above, and the in-place locking function when the switch is pulled to the right position is realized.
Example III
On the basis of the first embodiment, the switch has the function of automatically resetting the left position and the right position to the middle position, and the principle is as follows: when the switch is pulled to the left position from the middle position, the swing locking block 18 is limited in the extrusion mechanism and cannot reset, the reset spring 3 receives leftward pressure, if the sucker type electromagnetic locker 11 receives a control signal at the moment, the sucker type electromagnetic locker 11 adsorbs and locks the sucker type connecting rod 12, two ends of the sucker type connecting rod 12 are connected with the right conical pressing blocks 14, the right conical pressing blocks 14 on the left side and the right side are forced to be far away from the left conical pressing block 13, the distance is larger than the head size of the swing locking block 18, at the moment, the head locking limit of the swing locking block 18 disappears, and under the action of the releasing pressure of the reset spring 3, the handle rod 4 returns to the middle position and is limited by the V shape of the V-shaped contact plate 6 and stops at the middle position, so that the function of automatically resetting the switch from the left position to the middle position is realized. When the switch is pulled from the 'middle' position to the 'right' position, the principle is the same as that described above, and the process realizes the function of automatically resetting the switch from the 'right' position to the 'middle' position.
Example IV
On the basis of the first embodiment, the switch has the function of manually resetting the left and right positions to the middle position, and the principle is as follows: when the switch is pulled to the left position from the middle position, the swing locking block 18 is limited in the extrusion mechanism and cannot be reset, the reset spring 3 is subjected to left pressure, when the manual pulling force is larger than the pressure of the compression spring 15 in the compression mechanism when the handle rod 4 is manually pulled to the right position, the head of the swing locking block 18 can be separated from the compression mechanism, and under the action of the release pressure of the reset spring 3, the handle rod 4 returns to the middle position and is limited by the V shape of the V-shaped touch plate 6 and stops at the middle position, so that the function of manually resetting the switch from the left position to the middle position is realized. When the switch is pulled from the 'middle' position to the 'right' position, the principle is the same as that described above, and the process realizes the function of manually resetting the switch from the 'right' position to the 'middle' position.
