[0002] In the aviation industry, aircraft lavatory lighting control is a crucial aspect of ensuring passenger comfort and flight safety. Existing aircraft lavatory lighting control switches have several shortcomings. Firstly, some switches have complex structures composed of multiple delicate components, leading to high production costs and cumbersome installation and maintenance processes, requiring significant time and effort from specialized technicians. Secondly, the parts for some existing switches are difficult to obtain, making replacement inconvenient and potentially affecting the normal operation of the aircraft lavatory lighting system, thus negatively impacting passenger experience and flight safety. Furthermore, some switches experience a gradual decline in stability and reliability after prolonged use, becoming prone to malfunction and failing to effectively and promptly control the lighting, causing inconvenience to passengers and crew. Utility Model Content

[0003] The purpose of this invention is to provide a lighting control switch for an aircraft toilet, thereby solving the aforementioned problems in the prior art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An aircraft toilet lighting control switch includes a base, a bracket, a spring, a switch, and a cable. The base is used to connect to the upper-level components of the aircraft toilet. The bracket is positioned above the base and connected to it. The spring is installed on one end of the bracket near the base. The switch is fixed to one end of the bracket near the base and cooperates with the spring. One end of the cable is connected to the switch, and the other end is used to connect to the aircraft toilet lighting system to achieve electrical interconnection.

[0006] In some specific embodiments, the base 1 is a rectangular aluminum plate with through holes at both ends for connecting to the upper-level components; a square through hole and two countersunk holes are provided in the middle; the bracket 2 has a bracket through hole 14 near the base, which is aligned with the countersunk hole 13 of the base 1; the spring plate has a spring plate through hole 15 near the bracket; the bracket through hole 14, the countersunk hole 13 and the spring plate through hole 15 are connected in sequence by bolts or rivets, so that the bracket 2 extends upward perpendicular to the base 1.

[0007] In some specific embodiments, the bracket has multiple elongated holes 16. The top two elongated holes are located on both sides of the upper end of the bracket and are used to install cable ties. The bottom two elongated holes are located at the lower part of the bracket, close to the base. The switch is fixed to the bottom two elongated holes of the bracket by a support column, screws and nuts. The support column is located between the switch and the bracket and plays a protective role for the switch.

[0008] In some specific embodiments, the spring is a stainless steel sheet with one end in a trapezoidal shape, extending to the upper left of the switch; the other end is V-shaped and has two rivet holes located on the upper part of the bracket; the V-shaped end of the spring is connected to the bracket by rivets, and the trapezoidal end is suspended in the air. When the airplane toilet door is closed, the door moves the trapezoidal end of the spring through a mechanical structure, causing the spring to deform downward and press the switch.

[0009] In some specific embodiments, a cylindrical contact is provided on the upper left of the switch, and pressing the contact controls the on / off state of the switch; two holes are opened in the middle, which are connected to the bracket by screws and nuts to fix the switch on the bracket; the cylindrical contact of the switch faces the trapezoidal end of the spring, and the two are correspondingly matched.

[0010] In some specific embodiments, a rubber pad is also included. The rubber pad is adhered to the upper surface of the bracket and located at the upper part of the bracket. The upper half of the rubber pad is aligned with the middle part of the two elongated holes at the upper end of the bracket. The lower surface of the rubber pad is in contact with the upper surface of the bracket, and the upper surface is used to contact the cable tie to provide cushioning and anti-slip function when the cable tie is used to fix the cable.

[0011] In some specific embodiments, after the cable is connected to the switch, it bends and passes through the middle of the two elongated holes at the upper end of the bracket; the cable tie passes through the elongated holes and fixes the cable to the bracket; with the cable tie in place, the cable is close to the upper surface of the bracket and extends from the upper end of the bracket away from the base, preventing the cable from shaking and being damaged during use.

[0012] In some specific embodiments, a serrated sleeve is also included. Two serrated sleeves are respectively bonded to the uppermost two sides of the bracket, close to the edge of the bracket. The inner side of the serrated sleeve fits against the edge of the bracket to protect the outer sheath of the cable. When the cable passes through the position of the serrated sleeve, it is within the protection range of the serrated sleeve to prevent the cable from being worn by the edge of the bracket.

[0013] In some specific embodiments, two rivets are also included. One rivet is used to fix the connection between the base and the bracket. The rivet passes through the through hole of the base and the through hole at the bottom of the bracket to fix the base and the bracket together. The other rivet is used to fix the connection between the bracket and the spring. The rivet passes through the through hole at the V-shaped end of the spring and the corresponding through hole on the bracket to ensure the structural stability and connection reliability between the components.

[0014] In some specific embodiments, the size of the switch is adapted to the elongated hole at the bottom of the bracket. During installation, the two sides of the switch are respectively located in the length direction of the elongated hole. The switch is fixed by support columns, screws and nuts to ensure accurate installation position on the bracket. A certain distance is maintained between the lower surface of the switch and the base to accommodate the support column, so that the switch can stably change the switch state when the spring is pressed.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0022] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The diagram shows an aircraft toilet lighting control switch, comprising a base 1, a bracket 2, a spring 4, a switch 5, and a cable 9; the base 1 is used to connect to the upper-level components of the aircraft toilet; the bracket 2 is disposed above the base 1 and connected to the base 1; the spring 4 is installed on one end of the bracket 2 adjacent to the base 1; the switch 5 is fixed on one end of the bracket 2 adjacent to the base and corresponds to the spring 4; one end of the cable 9 is connected to the switch 5, and the other end is used to connect to the aircraft toilet lighting system to achieve electrical interconnection.

[0023] In this embodiment, the base 1 is the fundamental component of the entire lighting control switch and is made of a rectangular aluminum plate. This shape and material choice is designed to ensure sufficient strength and stability to support the various components above and withstand the various operating conditions that may be encountered during aircraft flight. Through holes are provided at both ends of the base 1. These through holes are key structures for connecting to the upper-level components inside the aircraft toilet. Bolts, screws, or other suitable fasteners are passed through these through holes to securely fix the base 1 to its designated installation position in the aircraft toilet. In addition, a square through hole and two countersunk holes are provided in the middle of the base 1. The square through hole may be used to reduce the weight of the base or to provide space for the installation of other components, while the countersunk holes are typically used to accommodate nuts or washers to ensure the flatness and reliability of the connection during installation.

[0024] The bracket 2 is positioned above the base 1 and aligns with a through hole on the base 1 via a through hole at its bottom. A secure connection is achieved using bolts, rivets, or other fasteners. The bracket 2 extends vertically upwards from the base 1, providing a mounting and support platform for components such as the spring 4 and switch 5. The bracket 2 also has multiple elongated holes, each with a different location and purpose: the two top elongated holes on either side of the upper end of the bracket 2 are primarily for installing cable ties 12. After passing through these holes, the cable ties 12 can secure the cable 9 to the bracket 2, preventing damage or loosening due to movement during use; the two bottom elongated holes are located at the end of the bracket 2 closest to the base 1 and are used to install the switch 5. The switch 5 is secured to these holes by support posts 6, screws 7, and nuts 8. The support posts 6, located between the switch 5 and the bracket 2, protect the switch 5 from direct impact or damage during use.

[0025] The spring 4 is a key component controlling the switch's operation. Made of stainless steel, it possesses excellent elasticity and durability. The spring 4 is mounted on the bracket 2 near the base 1. One end is trapezoidal, and the other is V-shaped, with two through holes at the V-shaped end. The V-shaped end of the spring 4 is connected to the corresponding position on the bracket 2 via rivets 10, allowing the spring 4 to swing or deform flexibly around the rivets 10. The trapezoidal end is located above the switch 5, corresponding to the cylindrical contact on the switch 5. When the aircraft toilet door closes, the door, through a mechanical structure (such as a linkage or lever, the specific structure depending on the actual design of the aircraft toilet), actuates the trapezoidal end of the spring 4, causing it to deform downwards and press the cylindrical contact of the switch 5, changing the state of the switch 5 and controlling the toilet lighting.

[0026] Switch 5 is the core component for switching the circuit on and off. It has a cylindrical contact on its upper left, which is the key point of interaction between switch 5 and spring 4. When the trapezoidal end of spring 4 is pressed, its downward deformation force is transmitted to the cylindrical contact, changing the internal circuit state of switch 5 and thus controlling the on / off state of the toilet light. Switch 5 has two holes in its middle, which, through the engagement of screw 7 and nut 8 with the elongated hole at the bottom of bracket 2, securely fix switch 5 to bracket 2. During installation, support column 6 is located between switch 5 and bracket 2, acting as a buffer and providing protection, ensuring that switch 5 can operate stably under repeated pressing of spring 4, while avoiding the risk of damage caused by direct rigid contact between switch 5 and bracket 2.

[0027] Cable 9 is a crucial electrical connection component linking switch 5 to the aircraft toilet lighting system. One end is securely connected to switch 5, while the other end extends to the corresponding interface of the aircraft toilet lighting system, enabling electrical interconnection between the two. The arrangement of cable 9 is meticulously designed. To ensure neat and aesthetically pleasing wiring within the aircraft toilet and to prevent interference with the normal operation of other components, after connecting to switch 5, cable 9 follows a specific path along bracket 2. For example, it bends and passes between two elongated holes at the top of bracket 2. Then, cable ties 12 are used to secure cable 9 tightly to bracket 2 by passing through the elongated holes. This prevents vibration and shaking of cable 9 during flight and avoids interference or wear between cable 9 and other components, ensuring long-term stable transmission of electrical signals and enabling switch 5 to effectively control the toilet lighting.

[0028] In some specific embodiments, the base 1 is a rectangular aluminum plate with through holes at both ends for connecting to the upper-level components; a square through hole and two countersunk holes are provided in the middle; the bracket 2 has a bracket through hole 14 near the base, which is aligned with the countersunk hole 13 of the base 1; the spring plate has a spring plate through hole 15 near the bracket; the bracket through hole 14, the countersunk hole 13 and the spring plate through hole 15 are connected in sequence by bolts or rivets, so that the bracket 2 extends upward perpendicular to the base 1.

[0029] In this embodiment, the base 1 is a rectangular aluminum plate. This shape design helps to provide a stable support platform and is compatible with the installation space inside the aircraft toilet. Through holes are provided at both ends; these through holes are key connection points for connecting to upper-level components. Fasteners such as bolts and screws pass through these through holes, allowing the base 1 to be firmly fixed in the designated position within the aircraft toilet, ensuring the stability of the entire lighting control switch. A square through hole and two countersunk holes are provided in the middle. The square through hole helps reduce the weight of the base while providing space for the installation or wiring of other components; the countersunk holes are used to accommodate nuts or washers, ensuring the flatness and reliability of the connection during installation and preventing fasteners from protruding and affecting the installation or normal use of other components.

[0030] In some specific embodiments, the bracket 2 has multiple elongated holes 16. The top two elongated holes are located on both sides of the upper end of the bracket 2 for installing the binding strap 12. The bottom two elongated holes are located at the lower part of the bracket 2, close to the base 1. The switch 5 is fixed to the bottom two elongated holes of the bracket 2 by the support column 6, screw 7 and nut 8. The support column 6 is located between the switch 5 and the bracket 2 and plays a protective role for the switch 5.

[0031] In this embodiment, the bracket 2 has a through hole at one end near the base, and the position and size of this through hole are precisely aligned with the first through hole 13 of the base 1. By passing bolts or rivets through these two aligned through holes, the bracket 2 can be securely connected to the base 1, allowing the bracket 2 to extend vertically upwards from the base 1. This vertical installation method not only provides a stable spatial structure for the various components above, but also helps to ensure the assembly accuracy and operational stability of the entire lighting control switch.

[0032] In this embodiment, the bracket 2 has multiple elongated holes 16. The two elongated holes at the top are located on both sides of the upper end of the bracket 2 and are mainly used for installing cable ties 12. After the cable ties 12 pass through these elongated holes, the cable 9 can be tightly fixed to the bracket 2, preventing the cable 9 from being damaged or loosened due to shaking during use. The two elongated holes at the bottom are located at the lower part of the bracket 2, close to the base 1, and are used for installing the switch 5. The switch 5 is fixed at these elongated holes 16 by support posts 6, screws 7, and nuts 8. The support posts 6 are located between the switch 5 and the bracket 2, which protect the switch 5 from direct impact or damage during use, and also help to accurately adjust the installation position of the switch 5.

[0033] In some specific embodiments, the spring 4 is a stainless steel sheet with one end in a trapezoidal shape, extending to the upper left of the switch; the other end is V-shaped and has two rivet holes located on the upper part of the bracket 2; the V-shaped end of the spring 4 is connected to the bracket 2 by rivets 10, and the trapezoidal end is suspended in the air. When the airplane toilet door is closed, the door moves the trapezoidal end of the spring 4 through a mechanical structure, causing the spring 4 to deform downward and press the switch 5.

[0034] In this embodiment, the spring 4 is made of stainless steel, which has good elasticity and durability. One end of the spring 4 is designed as a trapezoid, which extends to the upper left of the switch and corresponds to the cylindrical contact on the switch 5, ensuring that the switch 5 can be accurately pressed when subjected to external force. The other end of the spring 4 is V-shaped and has two rivet holes, located on the upper part of the bracket 2. The V-shaped end of the spring 4 is connected to the bracket 2 by rivets 10 passing through the rivet holes on the V-shaped end of the spring 4 and the corresponding through holes on the bracket 2. In this way, the trapezoidal end of the spring 4 can be suspended in the air, and when the airplane toilet door is closed, the trapezoidal end of the spring 4 can be moved by mechanical structures on the door, such as linkages or levers, to deform the spring 4 downwards, thereby pressing the switch 5 and controlling the toilet lighting.

[0035] In some specific embodiments, a cylindrical contact is provided on the upper left of the switch 5, and pressing the contact controls the on / off state of the switch; two holes are opened in the middle, and the switch 5 is connected to the bracket 2 by screws 7 and nuts 8 to fix the switch 5 on the bracket 2; the cylindrical contact of the switch 5 faces the trapezoidal end of the spring 4, and the two are correspondingly matched.

[0036] In this embodiment, a cylindrical contact is located on the upper left side of switch 5. This cylindrical contact is the key part where switch 5 interacts with spring 4. When the trapezoidal end of spring 4 is pressed, its downward deformation force is transmitted to the cylindrical contact, changing the internal circuit state of switch 5, thereby controlling the on or off of the toilet light. Two holes are opened in the middle of switch 5, which are connected to bracket 2 by screws 7 and nuts 8 to fix switch 5 on bracket 2. This fixing method not only ensures the stability of switch 5 during use, but also facilitates the installation and disassembly of switch 5, making maintenance and replacement convenient. The cylindrical contact of switch 5 faces the trapezoidal end of spring 4, and the two correspond and cooperate to ensure that the pressing action of spring 4 can accurately change the state of switch 5.

[0037] In some specific embodiments, a rubber pad 3 is also included. The rubber pad 3 is adhered to the upper surface of the bracket 2 and located at the upper part of the bracket 2. The upper half of the rubber pad 3 is aligned with the middle part of the two elongated holes at the upper end of the bracket 2. The lower surface of the rubber pad 3 is in contact with the upper surface of the bracket 2, and the upper surface is used to contact the cable tie 12 to provide cushioning and anti-slip function when the cable tie 12 fixes the cable 9.

[0038] In this embodiment, when the cable tie 12 passes through the elongated hole at the upper end of the bracket 2 and fixes the cable 9, the rubber pad 3 can provide cushioning and anti-slip function for the cable tie 12, preventing the cable 9 from being damaged by the fastening force of the cable tie 12 during the fixing process. It also reduces the friction between the cable 9 and the bracket 2, and extends the service life of the cable 9.

[0039] In some specific embodiments, after the cable 9 is connected to the switch 5, it bends and passes through the middle of the two elongated holes at the upper end of the bracket 2; the cable tie 12 passes through the elongated holes and fixes the cable 9 to the bracket 2; under the fixation of the cable tie 12, the cable 9 is close to the upper surface of the bracket 2 and extends from the upper end of the bracket 2 away from the base 1 to prevent the cable 9 from shaking and being damaged during use.

[0040] In this embodiment, after the cable 9 is connected to the switch 5, it is arranged along a specific path. The cable 9 is bent and passes between the two elongated holes at the upper end of the bracket 2. The cable tie 12 passes through the elongated holes and fixes the cable 9 to the bracket 2. With this fixing method, the cable 9 is close to the upper surface of the bracket 2 and extends from the upper end of the bracket 2 away from the base 1. This design not only makes the cable 9 neat and beautiful, but also effectively prevents the cable 9 from vibrating and shaking during aircraft flight, avoids interference or wear between the cable 9 and other components, and ensures that the cable 9 can transmit electrical signals stably for a long time, so as to realize the effective control of the toilet lighting by the switch 5.

[0041] In some specific embodiments, a serrated sleeve 11 is also included. Two serrated sleeves 11 are respectively bonded to the uppermost two sides of the bracket 2, close to the edge of the bracket 2. The inner side of the serrated sleeve 11 fits against the edge of the bracket 2 to protect the outer sheath of the cable 9. When the cable 9 passes through the position of the serrated sleeve 11, it is within the protection range of the serrated sleeve 11 to prevent the cable 9 from being worn by the edge of the bracket 2.

[0042] In this embodiment, the inner side of the serrated sleeve 11 fits against the edge of the bracket 2, forming a protective structure for the outer sheath of the cable 9. When the cable 9 passes the position of the serrated sleeve 11, it is within the protection range of the serrated sleeve 11, thereby preventing the cable 9 from being abraded by the sharp edge of the bracket 2. The design of the serrated sleeve 11 not only improves the service life of the cable 9, but also enhances the safety and reliability of the entire lighting control switch.

[0043] In some specific embodiments, two rivets 10 are also included. One rivet 10 is used to fix the connection between the base 1 and the bracket 2. The rivet 10 passes through the through hole of the base 1 and the through hole at the lower end of the bracket 2 to fix the base 1 and the bracket 2 together. The other rivet 10 is used to fix the connection between the bracket 2 and the spring 4. The rivet 10 passes through the through hole at the V-shaped end of the spring 4 and the corresponding through hole on the bracket 2 to ensure the structural stability and connection reliability between the components.

[0044] In this embodiment, the base 1 and the bracket 2 are firmly fixed together to ensure the strength and stability of the connection between them. Another rivet 10 is used to secure the connection between the bracket 2 and the spring 4. The rivet 10 passes through the through hole at the V-shaped end of the spring 4 and the corresponding through hole on the bracket 2, allowing the spring 4 to be securely mounted on the bracket 2 and to swing or deform flexibly. This design ensures the structural stability and reliable connection between the components, providing a solid foundation for the normal operation of the entire lighting control switch.

[0045] In some specific embodiments, the size of the switch 5 is adapted to the elongated hole at the bottom of the bracket 2. During installation, the two sides of the switch 5 are respectively located in the length direction of the elongated hole. The switch 5 is fixed by the support column 6, screw 7 and nut 8 to ensure that the installation position of the switch 5 on the bracket 2 is accurate. A certain distance is maintained between the lower surface of the switch 5 and the base 1 to accommodate the support column 6, so that the switch 5 can stably change the switch state when the spring 4 is pressed.

[0046] In this embodiment, the size of switch 5 is adapted to the elongated hole at the bottom of bracket 2. This size matching ensures that switch 5 can be accurately placed in the position of the elongated hole during installation. During installation, the two sides of switch 5 are respectively located along the length of the elongated hole and are fixed by support column 6, screw 7, and nut 8, ensuring that the installation position of switch 5 on bracket 2 is accurate. A certain distance is maintained between the lower surface of switch 5 and base 1 to accommodate support column 6 and other connecting parts. This not only provides sufficient room for movement for switch 5, but also ensures that switch 5 can stably change the switching state when the spring 4 is pressed, thereby achieving precise control of toilet lighting.

[0047] The working principle of this utility model:

[0048] The working principle of this utility model aircraft toilet lighting control switch is based on the combination of mechanical transmission and electrical control. Its core is to realize the automatic control of the toilet's interior lighting through the closing action of the aircraft toilet door and the linkage of a series of mechanical components.

[0049] When the airplane lavatory door is open, the trapezoidal end of spring 4 remains in its natural state without external force, and switch 5 is in the off state, turning off the lavatory lights. When the airplane lavatory door is closed, the mechanical structure on the door, such as the linkage or lever, will actuate the trapezoidal end of spring 4. Because spring 4 is elastic and one end is fixed to bracket 2, it will deform downwards under external force, and its trapezoidal end will press down on the cylindrical contact on switch 5.

[0050] When switch 5 is pressed by spring 4, the internal circuit state changes from open to closed, forming a circuit. Current flows through cable 9 between the aircraft toilet lighting system and switch 5, thus illuminating the toilet's interior lights and providing illumination for passengers. Once the aircraft toilet door is reopened, the mechanical structure on the door removes the external force on spring 4, and spring 4 returns to its initial state due to its elasticity. Switch 5 also returns to the open state, cutting off the circuit and turning off the toilet lights.

[0051] Throughout the entire process, the various components work closely together, using simple mechanical and electrical principles to achieve automated and intelligent control of the aircraft toilet lighting. This eliminates the need for manual operation by passengers, improving ease of use and comfort, while also meeting the stringent safety and reliability requirements of aviation equipment.

[0052] The working method of this utility model:

[0053] (I) Installation Method

[0054] Place base 1 in the predetermined installation position of the aircraft toilet, aligning the through holes at both ends of base 1 with the corresponding connection holes of the upper component.

[0055] Use bolts or rivets to secure the base 1 firmly inside the aircraft toilet by passing them through the through holes at both ends of the base 1 and the connection holes of the upper component.

[0056] Align the through hole at one end of the bracket 2 near the base 1 with the first through hole 13 of the base 1, and use bolts or rivets to pass through these two through holes so that the bracket 2 extends upward perpendicular to the base 1, and ensure that the connection is firm and reliable.

[0057] The lower surface of the rubber pad 3 is attached to the upper surface of the bracket 2, and the upper half of the rubber pad 3 is aligned with the middle part of the two elongated holes at the upper end of the bracket 2 to complete the bonding and fixing of the rubber pad 3 on the bracket 2.

[0058] Place switch 5 at the two elongated holes at the bottom of bracket 2, ensuring that the two sides of switch 5 are aligned with the length of the elongated holes, and position support post 6 between switch 5 and bracket 2. Use screws 7 and nuts 8 to pass through the two holes in the middle of switch 5 and the elongated hole at the bottom of bracket 2 in sequence to fix switch 5 to bracket 2.

[0059] Align the rivet hole at the V-shaped end of the spring piece 4 with the corresponding through hole on the upper part of the bracket 2. Use rivet 10 to pass through the rivet hole at the V-shaped end of the spring piece 4 and the through hole of the bracket 2 to fix the spring piece 4 on the bracket 2, so that the trapezoidal end of the spring piece 4 is suspended and extends to the upper left of the switch 5.

[0060] Connect one end of cable 9 to switch 5, ensuring a secure and reliable connection. Bend cable 9 and pass it through the middle of the two elongated holes at the top of bracket 2. Pass cable tie 12 through the elongated hole at the top of bracket 2 to secure cable 9 to bracket 2, making cable 9 close to the upper surface of bracket 2 and extending from the top of bracket 2 away from base 1.

[0061] Two serrated sleeves 11 are respectively glued to the uppermost two sides of the bracket 2, close to the edge of the bracket 2, so that the inner side of the serrated sleeve 11 fits against the edge of the bracket 2, providing protection for the outer sheath of the cable 9.

[0062] Connect the other end of cable 9 to the corresponding interface of the aircraft toilet lighting system to ensure that the electrical connection is correct and secure, so as to achieve electrical interconnection between the lighting control switch and the aircraft toilet lighting system.

[0063] (II) Operating Method

[0064] When a passenger enters the airplane lavatory and closes the lavatory door, the mechanical structure on the door, such as the linkage and the lever, will contact the trapezoidal end of the spring 4.

[0065] As the toilet door continues to close, the mechanical structure applies a force to the spring 4, causing the spring 4 to deform downwards against its own elasticity, and its trapezoidal end gradually approaches the cylindrical contact of the switch 5.

[0066] When the trapezoidal end of the spring 4 is pressed onto the cylindrical contact of the switch 5, the internal circuit state of the switch 5 changes from the open state to the closed state, forming a circuit.

[0067] Current flows through cable 9 from the aircraft toilet lighting system to switch 5, and then through switch 5 to the toilet lighting fixtures, illuminating the fixtures and providing lighting for passengers.

[0068] When the passenger finishes using the toilet and opens the toilet door, the force exerted by the mechanical structure on the door on the shrapnel 4 disappears.

[0069] The spring 4 returns to its initial state under its own elastic force, and its trapezoidal end leaves the cylindrical contact of the switch 5. The switch 5 returns to the open state under the action of the internal spring or other reset device, cutting off the circuit.

[0070] The current stops flowing, the toilet lights go out, and one lighting control cycle is completed.

[0071] Example

[0072] In a toilet renovation project for a medium-sized passenger aircraft, the lighting control switch of this utility model for the aircraft toilet needed to be installed.
