    Electric switch
    The present invention relates to an electrical switch, comprising a key, whose actuation connects or disconnects an electrical device. Background of the invention
    The currently known electrical switches comprise a key mounted on a base provided with a drive point, said rocker key being around a rocker axis. This key defines two positions: a first contact or electrical connection position and a second disconnection or rest position.
    15 From this second rest position, when the user presses the key, it goes to the first contact position, where it can be held or, if desired, can automatically return to the second position, for example by means of a spring. When this automatic return occurs, each time the key is pressed, the electrical contact will be switched on and off when the button is pressed, or it will be switched on and off.
    20 alternatively the electrical contact when the key is pressed.
    In these electrical switches in which the key automatically returns to its resting position, they can be mechanical or electronic. Electrical switches of this type that use electronic mechanisms for electric actuation have the
    25 advantage that the pressure to be applied on the key is reduced compared to the electrical switches with a mechanical mechanism. However, these electronic mechanisms are substantially more expensive than mechanical mechanisms and make the cost price of the electrical switch more expensive.
    30 In electrical switches of this type with a mechanical mechanism, the pressure to be applied on the key is greater, since the elastic force provided by two springs must be exceeded, one for the actuation of a tilting contact, and another for the return of the key to the rest position. In addition, the need for two springs makes the cost of the electrical switch more expensive.
    35 An example of this type of electrical switch is described in document ES 1 064 532
    image2
    U, of the same owner as this application.
    Therefore, the objective of the present invention is to provide an electrical switch with a mechanical mechanism that gives the user the sensation of using an electronic type switch, but with the price of a mechanical type switch. Description of the invention
    With the electrical switch of the invention, the aforementioned drawbacks are resolved, presenting other advantages that will be described below.
    The electrical switch according to the present invention comprises at least one rocker key around a rocker axis and a base provided with at least one electrical connection and disconnection actuation point for each key, so that the
    Toggle of the key presses said actuation point and causes the displacement of an axis, which rotates a tilting contact that causes the electrical connection or disconnection, and is characterized in that said axis is associated with a connecting rod, which is what transmits the rotation movement to said tilting contact.
    According to a preferred embodiment, said connecting rod comprises two projections at the end furthest from the actuation point, one of which contacts said tilting contact in its turning movement to cause the electrical connection or disconnection.
    Furthermore, advantageously said connecting rod comprises a first inclined surface and said axis
    25 comprises a second inclined surface, said inclined surfaces being in contact with each other when the key is pressed.
    Preferably, the end of said axis furthest from said drive point comprises a portion offset from the rest of the axis, said second being defined.
    30 inclined surface in said deflected portion.
    Advantageously, the connecting rod also comprises a contact portion next to, or after, said first inclined surface, the end of the shaft being furthest from the actuation point in contact with said contact portion.
    The electrical switch according to the present invention preferably comprises a helical spring disposed around said axis.
    image3
    According to a preferred embodiment, the switch also comprises a resting area of the tilting contact. The resting area of the tilting contact extends
    5 preferably in the direction perpendicular to the axis of the connecting rod, so that it reduces the angle of travel of the contact to the rest position. This additional resting area has an extension such that the angle that forms an axis that passes through the point closest to the axis of the connecting rod and the base of the tilting contact with the vertical that passes through the axis of the connecting rod is less than 0 degrees
    10 With the resting area of the tilting contact, the driving force can be reduced.
    With the electric switch according to the present invention, the user's feeling is that it uses an electronic switch, although in reality it is a mechanical switch, since
    15 The pressure that must be exerted on the key is similar to electrical switches of this type with electronic mechanism, only being necessary to overcome the elastic force of a spring. In addition, its cost is even lower than in known electrical switches with mechanical mechanism, since it does not require a second spring. 20 Brief description of the drawings
    For a better understanding of how much has been exposed, some drawings are attached in which, schematically and only by way of non-limiting example, a practical case of realization is represented.

    Figures 5 and 6 are schematic views of the lower part of the electrical switch of the present invention in its resting position; Y
    5 Figures 7 and 8 are schematic views of the lower part of the electrical switch of the present invention in its operating position; Description of a preferred embodiment
    10 In Figures 1 and 2 the upper part of the electrical switch according to a possible embodiment of the present invention is shown to facilitate a complete understanding of the present invention. This upper part of the electrical switch could be conventional, as in any electrical switch currently known.
    The electrical switch according to the present invention comprises one or more bases 2 and one or more keys 4. In the case of using more than one key 4, preferably each key is the same size.
    Furthermore, said base 2, or each base 2, is provided with a drive point 3 of
    20 connection and disconnection, each key 4 being tiltable with respect to a tilt axis 5, whose tilt presses said actuation point 3 and causes the electrical connection or disconnection.
    In Figures 1 and 2 it can be seen that the base 2 comprises a tilting actuator 6
    25 formed by a proximal section 6a and a distal section 6b, which define an angle (a). For example, said angle (a) is greater than or equal to 90 ° and may preferably be between 110 ° and 130 °, for example, 120 °.
    Furthermore, said proximal section 6a of the actuator 6 comprises a rotation axis 7 in its
    30 end furthest from the center of the base and said distal section 6b is in contact with the actuation point 3 when said key 4 is pressed.
    Figures 3 and 4 show the lower part of the electrical switch according to the present invention.
    The electrical switch comprises an axis 1, on which an actuation point 3 acts.
    image5
    Said axis 1 is longitudinally movable, and around it a helical spring 13 is arranged. The axis has at least one connection point with the helical spring 13 at a height close to its end closest to the actuation point 3.
    5 Said axis 1 is associated with a connecting rod 9, which is rotatable or tilting between the positions shown in figures 3 and 4. Said connecting rod 9 is the one that displaces a tilting contact 8, which determines the electrical connection or disconnection. Said displacement is carried out by means of a pair of projections 12 of the connecting rod 9, which are arranged at the end furthest from the actuation point 3. One end of the rocker contact 8 is
    10 is located between the projections 12 of the connecting rod 9 so that the movement of the connecting rod 9 pushes the end of the tilting contact 8 causing its tilting with respect to its other end that remains fixed at a point 15 of the bottom of the housing located between the electrical contacts, so that the surface of the rocker contact will go from being free in the disconnected state to contact the electrical contact in the connection state.
    Said connecting rod 9 further comprises a first inclined surface 10, disposed at the opposite end to said projections 12. At said end the connecting rod 9 also comprises a contact portion 14.
    20 For its part, said axis 1 comprises at its furthest end with respect to the actuation point 3 a portion displaced with respect to the rest of the axis 1, which defines a second inclined surface 11.
    In the rest position, when key 4, shown in figure 3, is not pressed, the
    25 distal end of the displaced portion is in contact with said contact portion 14 of the connecting rod 9. On the other hand, in the operating position, when the key 4, shown in Figure 4, is pressed, both inclined surfaces 10 of the connecting rod and 11 of axis 1, are in contact with each other.
    The switch of the present invention can also comprise a rest zone 15 of the rocker contact 8. The rest zone 15 of the rocker contact preferably extends in the direction perpendicular to the axis of the connecting rod 9, so as to reduce the travel angle from the contact to the rest position. This resting area 15 has an extension such that the angle that forms an axis passing through the nearest point
    35 to the axis of the connecting rod and the base of the tilting contact 8 with the vertical that passes through the axis of the connecting rod 9 is less than 0 degrees.
    image6
    The operation of the electrical switch according to the present invention is as follows.
    5 When a user wishes to activate or deactivate an electrical device, press the key 4, through an actuator 6 the actuation point 3 is pressed, which causes the longitudinal displacement of the axis 1 (downwards according to the position shown in the figure 3).
    10 This longitudinal displacement of the axis 1 causes the tilting of the connecting rod thanks to the deviated portion of the axis 1, which in turn causes the displacement of the tilting contact 8 by the projections 12 of the connecting rod 9.
    When the button 4, the rocker contact 8, the connecting rod 9 and the shaft 1 15 are not pressed again, they will return to their resting position by the action of the coil spring 13.
    Although reference has been made to a specific embodiment of the invention, it is apparent to one skilled in the art that the described electrical switch is susceptible to numerous variations and modifications, and that all the mentioned details may be
    20 replaced by other technically equivalent ones, without departing from the scope of protection defined by the appended claims.
