Surface-mounted four-position wall switch housing structure

Abstract

The invention discloses a surface-mounted four-position wall switch housing structure, which comprises a base frame, a functional key, and four switch buttons. Fixing holes are disposed in four corners of the base frame. The profile dimension of the base frame is 86MM*86MM. The functional key is of an integrated compact structure and is inlaid in the base frame. The four switch buttons are buckled on the functional key. A plurality of installation positioning corners are disposed on the base frame and on the edges of the fixing hole and are capable of supporting the caps of nails for fixing the base frame and shot by a nail gun. When installed side by side, the four-position wall switch and a common surface-mounted switch both have a profile dimension of 86MM*86MM so that the four-position wall switch and the common surface-mounted switch well coordinate with each other and are lower in production cost as compared with those with an original profile dimension of 108MM*86MM. Further, since the plurality of installation positioning corners are disposed on the base frame and on the edges of the fixing hole, the installation positioning corners may support the caps of the nails when the nails are shot by the nail gun into the fixing holes. Thus, the base frame of the switch can be quickly fixed to a wall surface. High-efficient installation and good installing firmness are achieved.

Description

technical field [0001] The invention relates to the field of electrical switches, in particular to a shell structure of a surface-mounted four-position wall switch. Background technique [0002] The surface-mounted four-position wall switch is one of the most commonly used wall switches. At present, the shell of the surface-mounted four-position wall switch on the market is generally 108 models, such as figure 1 As shown, including the bottom frame 1 and 4 switch buttons 3 and other components, that is, the appearance size of the bottom frame 1 of the surface-mounted four-position switch is 108MM×86MM, while the appearance size of the ordinary surface-mounted switch is 86MM×86MM. When the surface-mounted switches are installed in one position at the same time, because the length of the ordinary surface-mounted switch is shorter than that of the surface-mounted four-position switch, when the two switches are installed together at the same time, the appearance appears very unc...

Problems solved by technology

At present, the installation and fixing holes 5 of the four-position switch bottom frame 1 on the market are straight-through. This installation and fixing holes 5 can only be manually installed by the installer to fix it on the wall. It takes a lot of time, and the installation efficiency of general electricians is extremely low, and the current labor cost is relatively high. Therefore, electricians basically use nail guns for other installations. The hole 5 nail gun cannot be used. If a nail gun is used, the nail gun will pass through the bottom frame of the surface mounted four-position switch and cannot be fixed. Therefore, this surface-mounted four-position switch is not only inconvenient to install, but also a weakness in the sales process
