Description

Switching mechanism for devices recessed electric.

This utility model refers to a switching mechanism applicable to electrical mechanisms recessed, in low voltage electrical installations, and whose Essential features are described below.

The obvious current trend of the technique, in concerning the components of electrical installations, and in especially low voltage, for homes, small shops, offices and similar, is the normalization of said components, with specific dimensions and shapes that allow their Quick and economical replacement, both because of a necessary repair, as in the case, also frequent, of a change in the installation configuration, so the possibility of this quick replacement and no need to do any work, or previous or complementary, allows to streamline and simplify to the maximum these changes, especially considering the feature built-in special of the installation itself.

The switching mechanism object of the present utility model presents the essential characteristic of being configured within an element, as a closed, easily located inside the frame and support of the set recessed, element that will allow, immediately, to be carried out the dual switch configuration, as well as, in a third configuration, adapt a body for triple mechanism switching, all without having to make any changes in the components of the recessed assembly.

Likewise, and as an embodiment variant that it also offers the mechanism as a feature, the provision of the contacts inside the mechanism body as well as the design of the same, allows, by a simple elimination of one of them, adapt the switch to the specific function of switch, without any other change.

According to the drawings that have been referenced, the switching mechanism is constituted by the body-base (1), closed by the cover (2), in whose upper part is located the swingarm (3), on which position the external rocker switch (4) for operating the set, completing all this with the frame (5) that is fixed on the pins (7) of the frame (6), leaving the outer key (4) located in the central quadrangular opening (5a) of the frame (5).

In its different configurations, the variant Two switching mechanisms are presented with two identical base bodies (1), together with the totality of components located therein, and covers (2) also equal, such as so are the two swingarms (3), all positioned suitably in the central opening (5a) of the frame (5).

Only the outer keys of drive, which in this configuration will be two, (4a) and (4b) identical, independently operable and, consequently, acting, also independently, on the corresponding swingarm (3) of each mechanism.

In triple mechanism configuration switch, a single body-base (1a) is arranged, in whose interior the components of the three sets that constitute these three mechanisms, body-base (1a) closed by a cover (2a) also unique, and whose top three swings appear (3a), somewhat different externally from the swingarms (3) of Unitary mechanism and double mechanism.

Also, this triple mechanism configuration requires three outer keys (4c), (4d) and (4e), being (4c) and (4e) identical, tilting independently of one of the others.

As described above, and in any of these three configurations, once placed the mechanisms through the central opening (5a) of the frame (5), the the whole assembly is embedded, being visible from the outside the frame (5) and the outside key (4), or its variants of double key (4a) and (4b) and triple (4c), (4d) and (4e).

The mechanism, installed inside the body-base (1), it is characterized, first, by the cover (2) covering said base body (1).

This cover has guides (8) on its faces sides for placement on the protruding tabs (9) that it has the base body (1) outside its lateral faces, guided by vertical projections (10), allowing the fitting and locking of the lid (2) on the base body (1).

On the two extreme faces of the base body (1) there are two pairs of tabs (11) with their ends horizontally (12), which allow the centering and guiding of the lid (2) on the base body (1), leaving the upper ends (13) of said lid positioned at the same level as the top bent (12) of the tabs (11), while the tabs (14) of the ends of the cover (2) allow the fixing of the base-assembly (1) and cover (2) to the frame (6).

The swingarm (3) emerges through the opening rectangular central lid (2) of the body-base (one). This swingarm has two sides of two sides support (15), of triangular section and curved base, which will remain supported inside the lateral openings (16) that the cover (2) in matching places.

These lugs (15) will allow, thus placed, the swinging of the swingarm (3), since the openings (16) where fit are of similar profile, curved base and triangular section, which the mentioned support studs (15).

The swingarm (3) has on its upper face two holes (17) with a striated interior surface, where the studs (18) that has the outer key (4) on its lower face, leaving in this way fully external key (4) and swingarm (3).

In the variants of embodiment in which the device is provided with two mechanisms, the two keys exterior (4a) and (4b) will both be provided with studs (18), for fitting and fixing, also by pressure, in the respective tilting, while in the realization with three mechanisms, each of the three outer keys (4c), (4d) and (4e), are also provided with studs (18).

The swingarm (3) has on its lower face the projection (19) which is the support of the upper end of the stud cylindrical (20), which activates the contact (21), which, by tilting on the lower contact (22), it is positioned, in its tilting, towards the lateral contact (23) or the opposite contact (24), in its switch function

These contacts, the lower one (22) and the two lateral (23) and (24), positioned in the corresponding places inside the body-base (1), they are fixed by the cover (2). These contacts are provided with screws threading and the respective rear fixing nuts (26).

On the cylindrical stud (20) that leads to carry out the actuation of the contacts from the swingarm (3), the cylindrical spring (27) is located, which, being directly on the rocker contact (21), as the Figure 5, transmits the impulse generated by the swingarm (3) and the cylindrical stud (20) to tilting contact (21).

Regarding this mechanism component, the swingarm, in the realization of the device with three mechanisms, according to figures 3 and 13, differ from the swingarm (3) used in the configurations of one and two mechanisms, having said swingarm (3a) the side studs (15a) of shorter length outgoing, in order to occupy less space because they are three swingarms located next to each other.

Finally, the possibility of a configuration variant, by simply removing one of the side contacts (23) or (24), located inside the base body (1) as shown in figure 18, with what the mechanism will serve only as a switch.

Described sufficiently the object of the present utility model, it should be noted that any variation in shapes and dimensions, appearance and finish, as well as types of materials used, will not alter the essentiality of the invention which is summarized in the following claims.
