    image 1 DESCRIPTION
    Electric switch
    The present invention relates to an electrical switch, in particular an electrical switch comprising a rocker operated key. Background of the invention
    The electrical switches currently known comprise a key mounted on a base provided with an actuation point, said key being tiltable around a tilt axis. This key defines two positions: a first contact position
    or electrical connection and a second disconnection or rest position.
    From this second rest position, when the user presses the key, it goes to the first contact position, in which 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 connected and disconnected when the key is stopped, or the electrical contact will be switched on and off alternately when the key is pressed.
    In these electrical switches in which the key automatically returns to its resting position it is usual that said key substantially protrudes from the base at its end furthest from the tilt axis. The reason is the presence of a mechanical mechanism for the electric drive, which occupies a considerable space.
    To solve this problem, electrical switches of this type are also known which use electronic mechanisms for electric actuation, which have the advantage that the key barely protrudes from the frame at its end furthest from the tilt axis. However, these electronic mechanisms are substantially more expensive than mechanical mechanisms and make the cost price of the electrical switch more expensive.
    Therefore, the objective of the present invention is to provide an electrical switch in which the key protrudes approximately the same as the currently known electronic switches that automatically return to their resting position, but by a fully mechanical mechanism. In this way, the feeling that a user has is that of using an electronic type electrical switch, but in reality it is a mechanical type electrical switch.
    image2 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 electric switching and switching off point for each key, so that the key rocker presses said actuation point and causes the electrical connection or disconnection, and is characterized in that the base comprises a tilting actuator for each actuation point formed by a proximal section and a distal section, which preferably define an actuation angle.
    Advantageously, said proximal section of said actuator comprises an axis of rotation at its end furthest from the center of the front surface of the base and said distal section is in contact with the actuation point when the key associated with it is pressed.
    According to a preferred embodiment, said distal section comprises a projection for contacting said actuation point.
    Preferably, the distal section forms an angle with a normal axis to the base of the key at the actuation point between 0 and 90 degrees.
    In a preferred embodiment, the relationship between the distance traveled by the end of the distal section furthest from the axis of rotation in the direction perpendicular to the base, and the distance traveled by the end of the key farthest from the axis of tilt in the perpendicular direction the base is between 0.7 and 3, it being more preferred that said ratio is between 0.8 and 2 and more preferably about 1. In this way a compromise is obtained between minimum travel of the end of the key furthest from the tilt shaft and driving force.
    Furthermore, it is provided that the distance that the free end of the distal section travels in the direction perpendicular to the base can be advantageously between 2.5 and 1.5 mm, for example 2 mm, and the distance traveled by the end of The key furthest from the tilt axis in the direction perpendicular to the base is between 2.5 and 1.5 mm, for example 2 mm. In addition, the distance traveled by the center of the key is between 0.5 and 1.5 mm, such as 1 mm.
    image3
    With the switch according to the present invention, a low-cost mechanical type electrical switch is achieved which automatically returns to its resting position, and which for the user has the same feeling as an electronic type electrical switch.
    In addition, the force that the user must perform to operate the switch is the same as in conventional switches, since the key travel is the same. 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.
    Figure 1 is a sectional view of the electrical switch of the present invention in its rest position;
    Figure 2 is a sectional view of the electrical switch of the present invention in its operating position;
    Figures 3 and 4 are schematic views of the position of the key and the rocker actuator in the rest position and the operating position, respectively; Y
    Figure 5 is a plan view of the electrical switch of the present invention, comprising two bases. Description of a preferred embodiment
    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.
    image4
    Furthermore, said base 2, or each base 2, is provided with a connection and disconnection actuation point 3, each key 4 being tiltable with respect to a tilting axis 5, whose tilting presses said actuation point 3 and causes the connection or electrical disconnection
    In addition, each actuation point 3 is preferably located approximately in the center of each key 4, as can be seen in Figure 5.
    It should be noted that an electrical switch comprising two bases is shown in Figure 5. In order to allow the display of the actuator 6 and the bases 2, in this figure the corresponding keys 4 have been removed, and in the upper half the actuator 6 has been removed.
    In Figures 1 and 2 it can be seen that the base 2 comprises a tilting actuator 6 formed by a proximal section 6a and a distal section 6b, which preferably define a driving angle (a). For example, said drive angle (a) can be comprised between 175 ° and 5 °, preferably it is between 140 and 70 ° and more preferably 110 ° and 130 °, for example, 120 °.
    In addition, said proximal section 6a of the tilting actuator 6 comprises a rotation axis 7 at its end furthest from the center of the base and said distal section 6b is in contact at its free end with the actuation point 3 when said key 4 is located pressed. In this position the distal section forms an angle with a normal axis to the base of the key at the actuation point 3 which is between 0 and 90 degrees.
    In a preferred embodiment, the D3 / D2 ratio is between 0.7 and 3, it being more preferred that said ratio is between 0.8 and 2 and more preferably about 1, where D3 is the distance the end of the distal stretch travels. furthest from the axis of rotation in the direction perpendicular to the base, and D2 is the distance traveled by the end of the key furthest from the axis of tilt in the direction perpendicular to the base. In this way a compromise between minimum travel D2, driving force and proportions of the tilting actuator 6 with respect to the dimensions of the key is obtained.
    To determine the optimal value of the D3 / D2 ratio, two factors are taken into account: - Small D2 path that provides the effect of an electronic switch being mechanical. -Small drive force. The driving force, for a travel D2 of the determined key, increases with the travel D3 of the free end of the distal section for a given driving angle. The higher the drive angle, the greater the driving force for a distance D2 of the key and D3 of the free end of the determined rocker actuator. In small keys, the size of the tilting actuator 6 forces the defined angle between the distal section and a normal axis at the base of the key at the actuation point 3 to be between 0 and 90 degrees.
    image5
    So that D3 / D2 = 5 with a defined angle between the distal section and a normal axis at the base of the key at the drive point 3 between 0 and 90 would also have a small acceptable D2 travel but would increase the driving force , and D3 / D2 = 0.2 would have a small actuation force but the key travel D2 would be greater, so that in none of these cases would the desired electronic switch effect be obtained.
    According to a preferred embodiment, the distance D3 that travels the end of the distal section 6b furthest from the axis of rotation 7 in the direction perpendicular to the base 2 is advantageously between 2.5 and 1.5 mm, for example 2 mm , the distance D2 that travels the end of the key 4 furthest from the tilt axis 5 in the direction perpendicular to the base 2 is between 2.5 and 1.5 mm, for example 2 mm, and the distance D1 that travels The center of the key 4 is between 0.5 and 1.5 mm, such as 1 mm.
    The dimensions specified in the previous paragraph could be larger if the lengths L1 + L2 are greater.
    For a better understanding, the positions of the key 4 and the actuator 6 are shown schematically in figures 3 and 4, in the rest position (figure 3) and in the operating position (figure 4).
    These figures show the following reference points:
    P1: Point at which the intersection of the proximal 6a and distal sections 6b touches the surface
    image6
    internal of the key; P2: Maximum movement limit point of key 4; P3: Actuation point of the tilting actuator 6; L1: Distance between tilting axis 5 and point P1; L2: Distance between the axis of rotation 7 and the point P1.
    In one embodiment, the tilting actuator 6 optimizes the D3 / D2 ratio, so that: When P2 travels 2 mm (D2), P1 travels 1 mm (D1); When P2 travels 2 mm (D2), P3 travels 2 mm (D3); Setting the travel D2, and the driving angle a, when L1 increases, D3 increases and increases the driving force; Setting the travel D2, and the driving angle a, when L1 decreases, D3 decreases and decreases the driving force.
    As can be seen in Figures 1 and 2, when the key 4 is pressed at its furthest end of the tilt axis 5, the lower part of the key 4 pushes on the actuator 6, in particular, on the intersection between the section proximal 6a and distal section 6b.
    This thrust causes the actuator 6 to swing around the axis of rotation 7, so that the projection 8, or failing that the end of the distal section 6b closest to the axis of tilt 5, presses the drive point 3, causing the connection or electrical disconnection.
    When the user stops pressing key 4, the actuator 6 will automatically return to its resting position (shown in Figure 1). This automatic return is carried out by means of elastic means, for example, one or more springs, which are not shown in the figures, and which can be conventional.
    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 can be replaced by other technically equivalent ones. , without departing from the scope of protection defined by the appended claims.
