This utility model refers to an electrical mechanism designed for application in low voltage installations as double switch, characterized essentially for being endowed with a series of elements that allow fast and sufficient conduction of conductors with it related, elements that are characterized both by their structure as per the mode of placement and application, also being characteristic of said mechanism the arrangement of the base and the permanent connection with its cover, once the components of the  inside the mechanism. All this will be described in detail to throughout this report.

One of the basic peculiarities of electrical mechanisms used in low installations tension, usually domestic or in small shops, offices or similar, is to facilitate the installer's work to the fullest by presenting these mechanisms (switches, push-buttons, etc.) equipped with devices that allow carrying out, in the wiring process of the assembly, a quick busbar of the electrical conductors that affect the mechanism, both in the entrance as at the exit, ensuring that it is embornado it will be sufficient and permanent, establishing the electrical contact necessary and avoiding an accidental detachment of the driver, which will remain in this stable position.

The mechanism object of the present invention offers the advantages that meet the detailed requirements previously, being provided with a series of components suitable for carrying out this rapid emborning, complementing the mechanism with the appropriate provision of already known components, essential to complete the mechanism.

It is also an essential characteristic of double switch mechanism the fact of having only one entrance and two exits, each one corresponding to each switch.

In order to describe in detail the particularities of the mechanism, some drawings are attached in the which has been represented, by way of non-limiting example, a practical realization of it.

According to these drawings, the mechanism Electric double-switch with quick-flush is constituted by the base (1), whose lower part takes the form "V" feature, in order to leave more space to proceed to the wiring of the set, and on whose sides faced the keys of embornado (2), in two housings (3) located on the outside of the base (1).

Inside said base (1) it is located the set or group of contacts, grouped two by two, contacts known as the "knife" type (4) and (4a), open on its front face with a vertical opening (4b), similar to two facing blades, in which the end of the conductive cable (19) that is flanged. Two of those blade contacts (4) are supported by their bottom by the lower horizontal crossbar (5), which, being in "V" shape is positioned by its central hole (5a), on the cylindrical pivot (6) located on the inner bottom face of the body (1). The two other blade contacts (4a) remain located, facing the previous ones and in the opposite half zone of the base (1), housing all these blade contacts (4) and (4a) in the spaces (7) delimited by the located tabs inside the base (1). All these blade contacts they will be thus positioned, placing the opening (4b) that they have towards the outside, specifically towards the bottom of the lodgings (3) of the quick-flush keys.

This set of contacts already known, is complete, thus enabling its operation, with both mobile contacts (8) that support their base on the crossbar "V" bottom (5) of the blade contacts (4), so that can swing when driven by their respective cylindrical springs (9), components located inside each lower tower (10) of the two swingarms (11), which, at be operated independently by the corresponding key external push button, not shown in the drawings, will cause operation of this described set of contacts, corresponding to the application of double switch.

The cover (12) closes the mechanism assembly, when fixed on the base (1), as drawn in fig. 4, being locked by the action of the four teeth (13) that it has the base (1) at its upper edges corresponding to the sides where the blade contacts (4) and (4a) are positioned and that They fit in the entrees. (14) that has the cover (12) on the edge inside of your upper face. It is evident that the closure of the lid (12) on the basis (1) is done only when they have been placed, in advance, all the components of the mechanism, blade contacts, contact group, springs, etc.) in the inside of the base (1).

This cover (12), on whose lateral supports (15) the lateral pivots (11a) of each swingarm are supported (11), it has in its interior the necessary openings (16) for the step into the lower towers (10) of each tilting, towards the mobile contacts (8).

Each of the embossing keys (2), is provided, at its rear end, with two cylindrical bolts (17), axial in the sense of a transverse imaginary axis, which they will serve so that the key of embornado (2) is positioned in the side of the base (1), fitting these bolts (17) inside of the semi-cylindrical seats (18) that the base (1) possesses in the sides of the corresponding opening (3) where the embossing key (2).

The positioning and holding of the key Embedding (2) starts, as seen in Figures 2 to 4, placing it in a horizontal position to make it descend, to position their bolts (17) in the seats semi-cylindrical (18), then the lid (12) is placed and afterwards, the embossing key (2) is turned to its position stable initial, for the electrical conductor cable connection (19).

This fixing or clamping is carried out by the action of two protruding stops that the flange key (2) has (see fig. 5), practically next to its own edge. In first instead, the pin (24) is located inside the slit (25) that it has the base (1) and the pin (26) (just below the pin -24-), is located outside the base flange (1).

It has the key of embornado (2) a recess cylindrical (20) on its outer face (21), face provided with a Proper filleting for better grip. Inside this cylindrical cavity (20) the conductor end will be placed electric (19), until it stops at the bottom, next to the face inside (22) of the key, face arranged in the form of a fork and which delimits an upper opening (23) in which the front face of the blade contacts (4), where the openings (4b).

Thus placed the electric conductor (19), when start scrolling the embossing key (2), as see in figure 6, the front face of the blade contact (4) will penetrate into the upper opening (23) of the embossing key (2), acting on both sides of the opening (4b) as sharp elements, similar to two facing blades that they will affect the sides of the driver (19), cutting the plastic coating of the mentioned conductor and allowing the direct contact of said sides of the contact opening (4b) of blade (4) on the copper core of the conductor (19), the which, in addition, is sufficiently subject, imprisoned by its two sides, avoiding accidental detachment from it.

Figure 7 draws the end of the cycle, when already key (2) has remained in its final position, with its external face (21) inclined towards the inside of the lower part of the base (1), position in which said key will remain perfectly set.

This fixing or clamping is carried out by the action of a stud (27), which will initially be supported on the shoulder (28), which has the base (1) in the lower area of the Inner side of its side walls. At the end of rocker displacement of the key (2), it stably positioned according to fig. 7, leaving the third stud (27) located behind the shoulder (28) by means of a clipping action.

In this final stable position of the key lined (2), the conductor (19) remains perfectly embossed, after the retentive action of the flared key (2) and the blade contact (4), through its front opening (4b). As seen in fig. 7, this final stable position of each one of the keys of embornado (2) is towards the interior of the lower part of the base (1), almost coincident with the way "V" of it, occupying a minimum space and remaining protected.

Describe the characteristics sufficiently essentials of the electrical mechanism object of the present invention, It should be noted that any variation in dimensions, shapes, finish and types of materials used in the practical realization of mentioned mechanism, nothing will alter the essentiality of the invention, being summarized in the claims that follow.
