According to the mentioned drawings, the Pivot key electrical device, for push button, switch and switch, object of the present invention, are characterized in that it is formed by a base plate (1), which allows and facilitates the grip of the device in the indicated place of the wall, and which is provided with a central open space (2), of quadrangular shape, in which the key fits perfectly pivoting (3) of actuation of the electrical device.

This key (3), quadrangular and vertices rounded, it has two lateral lugs (4) that fit perfectly on some housings (5) that have the base plate (1) on two of the opposite walls of said space central open (2), all arranged so that the key (3) It can swing, pivoting on the aforementioned studs (4).

Inside the open space (2) of the base (1), space that is covered by the pivot key (3), accommodations are perfectly defined for the different connection terminals (6) and (7), up to a maximum of six terminals on the application of the device as a double switch, varying by consequently, the arrangement of said terminals and the connection corresponding, as required by each application.

These spaces are delimited inside of the body (1a), which constitutes the lower extension of the own motherboard (1).

The pivot key (3) has a spring cylindrical helical (8), located inside the housing hollow conical trunk (9) that has said key (3) on its face lower.

Said spring (8) rides on a pivot upper pop-up (10) of the contact acting as a rocker (11), centered and pivoting on the central terminal (7), so that, by the action of said spring (8), the contact (11) is It will swing to one side or another. The pivot (10) is nothing other than the result of stamping the contact plate (11) and doing so lift up.

In the application as a switch (Fig 1) and as button (Fig. 6) the mobile contact (11) has its surface in angle down and is provided, only in one of its ends, of a contact of noble material (12), since in both practical applications, the device has only two terminals, the center (7) and the end (6).

In the application as a push button (Figure 6), the Pivot key (3) has a housing (9a) on its lower face, located next to its edge, where another spring will be arranged cylindrical (8a) similar to (8) for return of said key to its initial position, once the user has finished pressing on said key (3).

In the application as a switch, according to Figure 8, the corresponding mobile contact (11a) is perfectly flat and has two contacts on both ends noble metal (12), which will alternately come into contact with the grains of noble material (13) that the terminals have extremes (6).

The mobile contact (11) or (11a), cited repeatedly, in which it has two side tabs (14), folded in parallel down, forming two indexes symmetrical "V" (15), which will be supported perfectly on the upper face of the central edge (7), located under the mobile contact (11), and which in turn presents two lace "V" shaped sides (16), leaving a space between the same.

The base plate (1) extends on its part inferior, constituting the body (1 a), where the housings (17), in a prismatic manner and up to a maximum of six, for the location of the side connection terminals (6) and central (7).

These terminals (6) (7) are characterized because their core "N" and its base "B" (see Figure 5) are constituted by a single mechanized piece, anticipating that said base "B", cylindrical, riveted on the body of the base (1) and also has an internal filleting, necessary for the threading of the corresponding screw of embornado (18) that guarantees the correct fixing of the electric cable that will be introduced through the side hole (19) of the "N" core.

It also features the device that is describe, because on the underside of the motherboard (1), and specifically on two of its opposite sides, the claws (20), arranged for anchoring and fixing said plate base (1) against the walls of the place where the device, whose claws will be operated from the outside, through of the screws (21).

In the device applications that describe, for the double switch functions (figure 4) and double switch (fig. 13), the base plate (1) has, in the partition central (22) that divides the central open space (2), and allows the  placement and perfect fit of two double pivot keys (3a) and (3b), half size, accommodation (23), where they fit precisely the side pivots (4) of said half keys (3a) and (3b).

In such practical applications (double switch and double switch), each of the two keys they will have all the mechanisms, independent, to each one of them, that allow their balancing, and with it, provoke the actuation of the corresponding mobile contact (11) and the contact with the corresponding terminals (6) and (7).

Described sufficiently the characteristics essentials of the electrical device provided with a pivot key, object of the present invention, it should be noted that any variation in dimensions, shapes, colors and exterior appearance, as well as type of materials used in the practical realization of the invention will not alter in any way its essentiality, which remains summarized in the following claims.
