Due to their high power consumption, these devices pose certain safety risks during operation. Therefore, various control modules or switch modules are needed to manage and operate the various functions of the equipment, requiring professional management. For example, in the control cabinet of a corridor ventilation system, operators need to operate different switches on the cabinet to start or stop the ventilation duct system on each floor. Currently, the control modules of such control cabinets mainly use conventional push-button switches to power on and off the equipment. These push-button switches are prone to accidental activation during daily operation, leading to abnormal equipment operation. This poses certain operational risks for high-power equipment and makes it difficult to meet the synchronous operation of multiple circuits, resulting in low operational efficiency. If a key switch with a simple structure, high stability and safety, capable of simultaneously switching multiple circuits could be designed, the above problems could be solved. Utility Model Content

[0006] Furthermore, the rotary switch driving end is provided with driving grooves on both sides, and the insulating driving seat mating part conforms to the driving grooves.

[0007] Furthermore, the lock cylinder assembly includes a lock cylinder shell and a lock cylinder body.

[0021] like Figures 1 to 6 As shown, in this embodiment, the present invention includes a switch assembly 1 and a lock cylinder assembly 2. The switch assembly 1 includes a switch base 3, a rotary switch 4, conductive sheets 5, and side-push conduction modules 6. The lower end of the rotary switch 4 is rotatably engaged with the middle of the switch base 3. Several conductive sheets 5 are disposed on both sides of the switch base 3. Several sets of side-push conduction modules 6 are respectively disposed between two sets of cooperating conductive sheets 5. A key 7 drives the rotating end of the lock cylinder assembly 2 to rotate and engage with the rotary switch 4. Several driving ends of the rotary switch 4 drive several sets of side-push conduction modules 6 to engage with several sets of conductive sheets 5. Therefore, by controlling the switch assembly 1 through the key 7 and the lock cylinder assembly 2 to achieve on / off switching, accidental switch activation can be effectively prevented. Only a one-to-one pairing of the key 7 can trigger the lock cylinder assembly 2 to achieve the on / off operation of the switch. This design is adaptable to various usage scenarios, with a simple structure and high security.

[0022] like Figure 4 and Figure 6 As shown, in this embodiment, the side-push conduction module 6 includes an insulating drive seat 61, a floating spring 62, and a docking piece 63. The docking piece 63 is disposed in the middle of the insulating drive seat 61. The two sets of insulating drive seats 61 are respectively floated and engaged with the fixed ends on both sides of the switch base 3 through the two sets of floating springs 62. The drive ends on both sides of the rotary switch 4 drive the contact ends of the docking pieces 63 on the two sets of insulating drive seats 61 to engage with the corresponding conductive pieces 5. Thus, during the rotation of the rotary switch 4, the insulating drive seat 61 can press the floating spring 6, thereby separating the docking piece 63 from the conductive piece 5 and achieving disconnection.

[0023] like Figure 4 and Figure 5 As shown, in this embodiment, the rotary switch 4 has driving grooves 8 on both sides of its driving end, and the insulating driving seat 61 has a mating part that conforms to the driving grooves 8. Therefore, the rotary switch 4 has arc-shaped structures on both sides, and the sliding side-push connection replaces the traditional overlapping power connection method, effectively preventing damage from excessive bending of the contact plate. It can simultaneously switch two sets of circuits, and for operating conditions requiring simultaneous opening or closing, synchronous operation of two sets of circuits can be achieved with a single switch.

[0024] like Figures 1 to 3 As shown, in this embodiment, the lock cylinder assembly 2 includes a lock cylinder housing 21 and a lock cylinder body 22. The lock cylinder body 22 is rotatably locked to the inner edge of the lock cylinder housing 21, and the driving end of the lock cylinder body 22 is limited to the limiting groove 9 at the upper end of the rotary switch 4. Therefore, when the lock cylinder body 22 is opened, the driving end can drive the rotary switch 4 to rotate, thereby enabling the side-push conduction module 6 to achieve either pressure-activated power-off or power-on restoration.

[0025] like Figure 1 and Figure 2 As shown, in this embodiment, a switch top cover 10 is provided on the upper end of the switch base 3, and the lock cylinder housing 21 is connected to the switch top cover 10. Therefore, the connection between the lock cylinder housing 21 and the switch top cover 10 allows the lock cylinder assembly 2 to stably control the rotary switch 4 to prevent it from shifting or falling off.

[0026] like Figure 3 As shown, in this embodiment, the outer edge of the lock cylinder housing 21 is provided with a locking thread 23, and the locking thread 23 is rotatably engaged with a locking rotating buckle 24. The switch top cover 10 is engaged with the external equipment mounting position through the locking rotating buckle 24. Therefore, the locking rotating buckle 24 can be rotated to adjust the tightness of the device mounting position, enabling quick locking or disassembly.

[0027] like Figure 3 As shown in this embodiment, the locking rotary buckle 24 is provided with a plurality of anti-slip protrusions 25 on both its upper and lower sides. Therefore, the plurality of anti-slip protrusions 25 can prevent the locking rotary buckle 24 from rotating and loosening during equipment operation.

[0028] like Figure 2 and Figure 3 As shown in this embodiment, a switch indicator 11 is provided on the upper surface of the lock cylinder housing 21, and a pointer 12 is provided on the upper surface of the lock cylinder body 22. The pointer 12 cooperates with the switch indicator 11. Therefore, the switch indicator 11 and the pointer 12 can quickly identify whether the device is powered on, preventing accidental operation.

[0029] like Figure 1 and Figure 2 As shown, in this embodiment, the switch base 3 has several wiring ports 13 on its outer side, and several conductive sheets 5 are connected to the terminals of external components through these wiring ports 13. Therefore, the wiring ports 13 can be used for wiring operations of the conductive sheets 5.

[0030] like Figure 5As shown in the figure, in this embodiment, a plurality of reinforcing ribs 14 are provided between the main body of the rotary switch 4 and the driving end of the rotary switch 4. Therefore, the plurality of reinforcing ribs 14 increase the overall strength of the rotary switch 4 and extend its service life.

[0031] The working principle of this utility model is as follows: Before starting the device, the lock cylinder housing 21 is connected to the device mounting position via the locking rotating buckle 24. Several lines in the device mounting position are connected to several conductive plates 5 via corresponding wiring ports 13. The main circuit switch is turned on, and the lock cylinder body 22 is driven to the open position by the paired key 7. The ends of the two sets of insulating drive seats 61 slide into the drive groove 8. The floating spring 62 stably presses the insulating drive seats 61 onto the drive groove 8. The two ends of the mating piece 63 are connected to the corresponding two sets of conductive plates 5 to achieve power supply. After the power supply operation is completed, the lock cylinder body 22 is rotated in the opposite direction to the closed position. The ends of the insulating drive seats 61 slide out from the drive groove 8. The floating spring 62 is compressed to separate the mating piece 63 from the conductive plate 5. The above operation is repeated to achieve synchronous connection or disconnection of multiple sets of circuits in the device.

[0032] Although the embodiments of this utility model are described with reference to actual solutions, they do not constitute a limitation on the meaning of this utility model. For those skilled in the art, modifications to the implementation schemes and combinations with other schemes based on this specification are obvious.
