[0034] The utility model discloses since switch 11 is triggered and is turned on indicating light source 12 to emit light, can make user immediately know that switch 11 has been triggered, and the mounting hole 22 is arranged corresponding to the key body 3, switch 11, can conveniently move the key body 3 along the axial direction of the mounting hole 22, and accurately triggers switch 11, simultaneously, the key body 3 is opposite to switch 11, and indicating light source 12 is adjacent to switch 11, can make the light that indicating light source 12 emits passes through the key body 3 and transmits outward, and the light transmission channel 32 and the reflecting surface 33 are arranged corresponding to indicating light source 12, can make the light that indicating light source 12 emits first passes through the light transmission channel 32, then is reflected by the reflecting surface 33 and transmits outward only, avoid the light of indicating light source 12 directly irradiates outward and causes light pollution.
[0035] Need to explain, switch 11 is electrically connected with the processing chip, and switch 11 is triggered to send a signal to the chip, and then the chip controls indicating light source 12 to brighten or extinguish.

[0037] The key column is a cross-shaped key column, which has better stability when bearing pressure and is less likely to deform or twist than a cylindrical column.
[0038] Specifically, in the embodiment, the key body 3 is provided with a light shielding skirt 34, which can block the light from transmitting or leaking between the key body 3 and the mounting hole 22.
[0039] In the embodiment, the first surface 21 is provided with a first extension 23 extending towards the mounting hole 22, and the first extension 23 is provided with a blocking end 231 configured to form a block in the moving direction of the key body 3, so that the key body 3 can no longer continue to press the switch 11, thereby avoiding the switch 11 from being damaged or having a reduced service life due to over-pressing during long-term use.
[0040] In one of the embodiments, the light transmission channel 32 is provided with a reflecting surface 33 at the end thereof, and the light shielding skirt 34 is arranged opposite to the reflecting surface 33. The reflecting surface 33 is arranged at an angle, so that the light emitted by the indicating light source 12 is reflected by the reflecting surface 33 to the upper surface of the light shielding skirt 34, thereby generating a light shadow. In this way, the intensity of the light seen by the user's eyes is greatly reduced, the light pollution phenomenon in the room is reduced, and the light emitted by the indicating light source 12 directly into the eyes is avoided, thereby reducing the damage to the vision and eyes.

[0042] Specifically, in the embodiment, the reflecting surface 33 is provided with a limiting step 35 extending therefrom, the limiting step 35 is matched with the blocking end 231, and a first gap for the sliding of the key body 3 is arranged between the limiting step 35 and the blocking end 231. When the key body 3 moves downward to abut against the limiting step 35 and the blocking end 231, the blocking end 231 prevents the key body 3 from continuing to move downward. In this way, the key has a certain stroke when being pressed, the user's hand feels comfortable, and the switch 11 is not damaged or has a reduced service life due to over-pressing. The limiting step 35 can also block the part of the light transmitted along the light transmission channel 32 and not reflected by the reflecting surface 33, thereby avoiding the light directly illuminating outside the device.
[0043] Specifically, in the embodiment, one end of the elastic arm 31 is connected with the key body 3, and the other end is fixedly connected with the shell 2. In this way, the key body 3 can rebound after being pressed by the user and return to the original position. The one end of the elastic arm 31 is fixedly connected with the shell 2, thereby providing a fulcrum for the elastic deformation of the elastic arm 31.
[0044] Specifically, in the embodiment, the elastic arm 31 extends in a curved shape; compared with extending in a straight line, the elastic arm 31 extending in a curved shape can better disperse stress, reduce the risk of cracking and breaking, thereby enhancing the durability and reliability of the elastic arm 31.

Through one-time injection molding, the elastic arm 31 part and the key body 3 part can be manufactured at the same time, reducing the assembly process and reducing production costs. Since the elastic arm 31 part and the key body 3 part are integrated, there is no joint or connection between them, so they have better structural stability and durability.
[0045] In addition, the other end of the elastic arm 31 and the shell 2 can be fixed by riveting or bolt fixing or other suitable methods.

[0047] The electrical device through the above-mentioned key structure, since the substrate 1 is provided with the switch 11 and the indicating light source 12, when the switch 11 is triggered, the indicating light source 12 is turned on to emit light, so that the user can immediately know that the switch 11 has been triggered; the mounting hole 22 is arranged corresponding to the key body 3 and the switch 11, which can facilitate the movement of the key body 3 along the axial direction of the mounting hole 22, and accurately trigger the switch 11; at the same time, the key body 3 is opposite to the switch 11, and the indicating light source 12 is adjacent to the switch 11, so that the light emitted by the indicating light source 12 can be transmitted outward through the key body 3; the light transmission channel 32 and the reflecting surface 33 are arranged corresponding to the indicating light source 12, so that the light emitted by the indicating light source 12 can first pass through the light transmission channel 32, and then be reflected by the reflecting surface 33 before being transmitted outward, avoiding the light pollution caused by the direct outward irradiation of the light of the indicating light source 12.
[0048] Specifically, the electrical device is a socket converter, and the user can control the on-off of the socket converter through the key operation device when the socket is not needed, thereby avoiding the situation that foreign matters enter the socket and cause circuit short circuit and fire during non-use time.
