[0020] Examples, such as Figures 1 to 8As shown, a reading light switch with mechanical tactile feedback includes a reading light housing 1, a faceplate 2 and a base 3 mounted on the reading light housing 1, and a circuit board assembly 4 mounted on the base 3. A switch mounting base 5 is fixedly mounted on the reading light housing 1, and a set of piano-key type toggle buttons 6 controlling different signals are arranged side-by-side on the switch mounting base 5. Each piano-key type toggle button 6 includes an inner shell 61 rotatably mounted on the switch mounting base 5, and a touch faceplate 62 mounted on the inner shell 61. To improve tactile feedback, the touch faceplate 62 has an anti-slip area 621. The inner shell 61 has a gear position trajectory 611 that provides the tactile feedback of the switch, and the switch mounting base 5 has a gear position pin 7 that acts on the gear position trajectory 611. The gear position trajectory 611 has a W-shaped structure, thereby providing the tactile feedback of moving the gear up and down. The shift pin 7 is placed inside the shift pin mounting seat 51 of the switch mounting base 5. A push-out spring 8 is provided inside the shift pin mounting seat 51 and below the shift pin 7. Under the action of the push-out spring 8, the top of the shift pin 7 always acts on the shift track 611. To ensure that the shift pin 7 moves in the vertical direction, vertically oriented latches 71 are provided on both sides of the shift pin 7. The shift pin mounting seat 51 is provided with a slot 511 that mates with the latches 71.

[0021] The inner shell 61 also extends downwards with a lever 612, and a slider 9 is provided below the lever 612. The slider 9 has a locking hole that matches the lever 612. The lever 612 swings to drive the slider 9 to move back and forth. The slider 9 is provided with a movable contact piece 10 that cooperates with the circuit board assembly 4 for conduction. The slider 9 is located below the circuit board assembly 4, and a slide block 11 is fixedly provided on the circuit board assembly 4. The slider 9 is slidably mounted on the slide block 11. To ensure the reliability of the circuit conduction, the slider 9 is provided with a movable contact piece mounting hole 91. A contact spring 12 is provided in the movable contact piece mounting hole 91 to push the movable contact piece 10 upwards.

[0022] To improve visibility, facilitate operation, and create an ambient lighting effect, an ambient light 13 is installed on the circuit board assembly 4. A light guide post 14, fitted onto the ambient light 13, is also installed on the circuit board assembly 4. A first light guide body 15 is located above the light guide post 14 inside the inner shell 61. The touch cover 62 has a triangular cross-section and is hollow, with light-transmitting holes 623 on both sides. A second light guide body 16 is installed inside the touch cover 62. The light from the ambient light 13 is emitted from the light guide post 14 through the first light guide body 15 and the second light guide body 16 from both sides of the touch cover 62, achieving the ambient lighting effect. To facilitate the assembly of the second light guide 16 inside the touch cover 62, a light guide mounting step 622 is provided inside the light-transmitting hole 623. The second light guide 16 includes a left light guide 161 and a right light guide 162 that are interlocked. During assembly, the left light guide 161 is inserted from the left side of the touch cover 62, and the right light guide 162 is inserted from the right side of the touch cover 62. When the end faces of the left light guide 161 and the right light guide 162 are pressed on the mounting step 622, the buckle on the left light guide 161 and the latch on the right light guide 162 are engaged to achieve assembly and fixation.
