According to these drawings, the mechanism electric for various applications (switch, push button, commutator) with quick-flush device, it is constituted by a base (1), whose lower part adopts the characteristic form in "V", in order to leave more space to proceed to the wiring of the set, and on whose side faces are place the corresponding embossing keys (2), located in two accommodations (3) located on the outside of the base (one).

Inside said base (1) the set or group of contacts, grouped two to two, contacts known as the "knife" type (4) and (4a), opened by its front face with a vertical opening (4b), similar to two facing blades, in which the end of the conductor cable (19) that is busted. In the application as Switch are two blade contacts (4), and two blade contacts (4a) while in the others they are only necessary three. The two of those blade contacts (4) are Solidarity at the bottom through a lower connector (5), characteristic of these contact groups. The other two blade contacts (4a) are located, facing the anterior and in the opposite half zone of the base (1), staying all these blade contacts (4) and (4a) in spaces (7) delimited by partitions located inside the base (one). All these blade contacts are thus positioned, placing outwardly the opening (4b) that they possess, specifically towards the bottom of the housings (3) of the keys of fast embornado.

This set of contacts already known, is complete, in the example that is represented and thus enabling its operation, with a mobile contact (8) that supports its base on the bottom connector (5) so that it can swing when driven by a cylindrical spring (9), located inside the lower tower (10) of the tilting element (11), which, at be operated by the external push button, not represented in the drawings, causes the operation of this set of contacts

Said lower connector (5) is fixed on a pivot (6) located at the bottom of the base (1).

A cover (12) closes the mechanism assembly, when fixed on the base (1), as drawn in figures 3 and 4, being locked by the action of four teeth (13) that it has said base (1) at its upper edges corresponding to the sides where the blade contacts (4) and (4a) are positioned and that fit in some starters (14) that has the aforementioned cover (12) on the inside edge of its upper face. It is evident that the closing of the lid (12) on the base (1) is carried out only when all components have been previously placed of the mechanism, (blade contacts, contact group, springs, etc.) inside the base (1).

This cover (12), on whose lateral supports (15) the lateral pivots (11a) of the element are supported tilting (11), has inside the necessary opening (16) for the passage into the lower tower (10) of said tilting element (11), towards the mobile contact (8).

A cylindrical spring (9a) is located under the front of the swingarm (11) in the necessary return action in the Application variant as push button.

Above the swingarm (11) is positioned the light emitting device (30) provided on its underside of the two contacts (31) which will be introduced inwards of the base (1) through the openings (12a) that the lid has (12) on its lower face.

Each of the embossing keys (2), is equipped, at its rear end, with two cylindrical bolts (17), axial in the sense of a transverse imaginary axis, which they serve so that the key of embornado (2) is positioned in the side of the base (1), fitting these bolts (17) inside of semi-cylindrical seats (18) that has the base (1) 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, previously placing it in a horizontal position to lower it until positioning their bolts (17) in the semi-cylindrical seats (18), then the lid (12) is placed and then the embossing key (2) to its stable starting position 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, a stud (24) is located inside the slit (25) that it has the base (1) and a stud (26) (just below the stud -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 recess (20) the conductor end is 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 fig. 6, the front face of the blade contact (4) penetrates into the upper opening (23) of the key of embornado (1), acting both sides of the opening (4b) as sharp elements that will affect the sides of the conductor (19), cutting the plastic coating of the mentioned driver and allowing direct contact of said sides of the opening (4b) of the blade contact (4) on the copper conductor core (19), which is also left sufficiently subject, imprisoned on both sides, avoiding the  accidental detachment of it.

Fig. 7 shows the end of the cycle, when already has been the key of embornado (2) in his final position, with his external face (21) inclined towards the inside of the lower part of the base (1), position in which said key will remain perfectly fixed, while keeping the embornado.

This fixing or clamping is carried out by the action of a stud (27), which is initially supported by a projection (28), which has the base (1) in the lower area of the face inside its side walls. At the end of the scroll tilt of the key of embornado (2), this one positions of form stable as shown in figure 7, leaving the third bumper (27) located behind the shoulder (28) by an action of clipping.

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 can be seen in the aforementioned figure 7, this position stable end of each of the embossing keys (2) is towards the inside of the lower part of the base (1), almost coincident with the "V" shape of it, occupying a minimum space and being perfectly protected.

As described above, the mechanism will present a practical base variant (1a), (figures 10 and 11) used in applications such as switch and push button, applications that require only three blade contacts, two contacts (4) and one contact (4a), as can be seen from the Figure 1. On the latter will affect, in its displacement tilting, the mobile contact (8), which in its position of "no contact "leans against a stop (29) that has this base (1a) instead of the corresponding space (7).

Finally, the mechanism is characterized by have a light emitting device (30), located above of the tilting element (11), and provided with two contacts (31) the which are introduced inside the mechanism through the openings (12a) that the cover (12) possesses, for the purpose practice of directly influencing the contacts that correspond for your specific function.

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.
