The invention relates to an electronic apparatus (1) comprising a chassis (2) inserted into a housing (10) having a face (11) parallel to the direction (D) of insertion of the chassis in the housing and provided with push buttons (20.1, 20.2, 20.3) provided with light guides (23.1, 23.2, 23.3) projecting into the housing. An electronic board (3) is mounted in the chassis so as to extend parallel to said face of the housing and is provided with switches (5.1, 5.2, 5.3) in order to interact with the push buttons and light sources (6.1, 6.2, 6.3) surrounded by a light-tight frame (7.1, 7.2, 7.3) receiving the free end of the light guides. The light-tight frame has a height which decreases in a direction of separation from the chassis and the light guides have a height which decreases in the opposite direction so as only to be in contact with one another once the chassis has been completely inserted into the housing. The invention also relates to a method for assembling such an apparatus.

A key structure includes a base, a keycap, and a connecting rod. The base includes a structural plate and a connecting plate. The connecting plate is configured on the structural plate. The keycap is configured on the structural plate and includes a plate body and a first hook. The connecting rod is configured under the structural plate and extending towards an extension direction. The connecting rod includes at least a second hook. The connecting rod moves along the extension direction relative to the base to drive the second hook to be fastened to or detached from the first hook. When the first hook is detached from the second hook, the keycap moves relative to the connecting rod to expose the space between the keycap and the base, and then the key structure is easily repaired or cleaned.
