The connector 320 has one end connected to the cap plate 310 and the other end connected to the reinforcement 330.

Assembled on the bracket 100 of a switch socket may be a set of face shells 300, that is, a cover plate 310 to which two reinforcing members 330 are connected, disposed on the left and right sides of the cover plate 310; two sets of face shells 300 may also be assembled, namely: two cover plates 310 near the mounting holes 120 at the left and right sides of the mounting hole 110 are respectively connected with a reinforcing member 330, which is matched with the mounting holes 120 at the same side.

In this embodiment, as shown in FIG. 1, the stiffener 330 is directly connected to the cover plate 310, and the encasement hole 110 is in communication with the counterbore 121. During installation of the face-piece 300, the cover plate 310 is secured to the rear seat 200 or the bracket 100 from the nest hole 110 while the stiffener 330 extends into the counterbore 121 and secures the stiffener 330 within the counterbore 121 and over the screw hole 122. The number and placement of the stiffeners 330 is matched to the number and placement of the mounting holes 120 in the bracket 100. The stiffener 330 is provided with a through hole 331 without limitation in the external shape thereof. In this embodiment, the bracket 100 is injection molded from PC plastic instead of PP plastic, and the face housing 300 is injection molded from PC plastic, thus ensuring that the reinforcement 330 has sufficient strength and rigidity to resist the pressure of the screw head. When the switch socket is installed, the bracket 100 is placed on the bottom box of the wall, and the screw is inserted into the counter bore 121, then inserted into the through hole 331 and the screw hole 122, and then connected to the bottom box for fixing.
