Description

Switch mechanism for devices recessed electric.

This utility model refers to a switch mechanism designed for application to mechanisms recessed electrical, in low electrical installations tension, and whose essential characteristics are described at continuation.

At present, the trend of the technique, in concerning the components of electrical installations, and in especially those of low voltage, in homes, offices, small shops and similar, is the interchangeability of them, providing them with concrete dimensions and shapes that allow their fast and economical replacement, whether a repair or replacement, as may be the case, too frequent, of a change of the configuration of the installation, by what the possibility of this quick and needless replacement to carry out any previous or complementary work, allows streamline and simplify these changes significantly, taking into account, in particular, the basic feature of an installation recessed

The switch mechanism object of the present utility model has the essential characteristic of being configured within a closed body, easily located in the interior of the frame and support frame of the recessed assembly, body that will allow, immediately, to carry out double switch configuration variants, as well as the switch variant equipped with a signaling light or Indicator of its activation.

A last and immediate variant is the push button configuration, usual switch variant on the that the actuation key, when stopped being pressed, returns to Your initial position. This variant is characterized by the addition of a component that causes this return of the outer key of drive to its initial position at the time of stopping exert any pressure on it.

In order to describe in detail what previously stated, a series of drawings in which practical realizations of the mechanism in the various application configurations.

According to the drawings that have been referenced, the switch 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) and the frame (6), frame that is fixed on the pins (7) of the frame, remaining the outer key (4) located in the quadrangular opening center (5a) of the frame (5).

In its different configurations, the variant Two switch mechanisms are presented with two identical base bodies (1), together with the totality of components located therein, and covers (2) also equal, two swingarms (3), depending on the type of configuration to be installed, all it properly positioned 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), independently operable and, consequently, acting, also independently, on the corresponding swingarm (3) of each mechanism.

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 body-base (1) there are two pairs of tabs (11) with its horizontally bent ends (12), which allow centering and guiding the cover (2) on the base body (1), the upper ends (13) of said cover being positioned at same level of the folded top (12) of the tabs (11), while the tabs (14) of the ends of the cover (2), allow the fixation of the body-base assembly (1) and the 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 side openings (16) that it has 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 in the respective swingarms.

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 tilting contact (21), which it rests on the lower contact (22), and is positioned, in its tilting towards the lateral contact (23).

These contacts, the bottom (22) and the side (23), positioned in the corresponding places inside the body-base (1), are fixed by the cover (2). Said contacts are provided with embossing screws (24), and of the respective rear fixing nuts (25).

On the cylindrical stud (20) that leads to carry out the actuation of the contacts from the movement of the tilting (3), the cylindrical spring (26) is located, which it rests directly on the rocker contact (21), as draw figure 7, transmitting the impulse generated by the swingarm (3) and the cylindrical stud itself (20), until the tilting contact (21).

With regard to the rocker (3), in the realization of the device as a push button, light switch and light switch, the rocker (3a) differs from the previous one (3). Figure 13 shows the basic differences between both swingarms: the swingarm (3a) has two lateral lugs (15a) of shorter length, to occupy less space, and a cylindrical stud (27), which is the point of fixation of the spring cylindrical (28), which is placed under this swingarm (3a), until it rests on the cover (2) of the base body (1), and whose purpose is to cause the return of this swingarm (3a), together with the key external (4) to it fixed, until its initial resting position, at the moment when the pressure is stopped on said key and, consequently, on the swingarm itself (3a). Figure 7 shows this practical embodiment of mechanism
button.

Also, the swingarm (3a) will present, as variant, an opening or window (29) to allow the exit of the light when the mechanism is provided with light. The rest of characteristics are identical for the swingarms (3) and (3a), respectively.

This practical configuration has identical mechanisms, both for switch, according to figure 4, as for button, according to figure 6, having been added only the support plate (30) of the LED (31), plate provided with a contact (32), located on its lower face, which it affects the lateral contact (23). This plate is attached around the cylindrical stud (20), leaving the led (31) located under the opening (29) of the swingarm (3a).

The brightness produced by the led (31) it will strike against the underside of the external key (4), through of the opening (29) of the swingarm (3a), being visible from the outside, generally, through a suitable opening or viewfinder located on the key itself.

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.
