Definitions

• Control device comprising a switch, control unit housing and switch for control device
• the present invention relates to a control device comprising a switch, for example a lock or a handle for an opening of a motor vehicle, in particular for a door, tailgate, tailgate or trunk.
• the invention also relates to a control device housing, and a control device switch.
• Certain control devices for motor vehicles include switches for electromagnetic control functions of conviction, assistance opening, closing or producing information displayed on the dashboard.
• Such a switch comprises a plunger, and is actuated by a translational movement of the plunger, from outside the switch housing towards the inside thereof.
• the switch can be controlled by a rotating cam contacting the outer end of the plunger. This is nevertheless feasible only when the angle of attack of the cam on the plunger, measured with respect to the axis of translation of the plunger, is low (less than 30 °), because otherwise the cam imposes constraints. transverse to the plunger, which is deviated from its translational movement. These constraints are likely to be destructive for the switch. Similarly, if the cam is animated with a too high angular speed, the switch is damaged.
• control devices are known in which the switch is provided with a pivoting control lever on the surface of the switch housing and engaging the plunger with a low angle of attack.
• This control lever is an insert that can be screwed or clipped to the surface of the switch housing.
• a control device for opening a transport vehicle comprising a housing, and in said housing, a switch equipped with a plunger, a cam mounted in rotation relative to the housing , and a movable member adapted to be driven by a transmission movement under the action of an action applied by the cam when it is driven by a rotational movement, said movable member being also fit, by said movement transmission, to apply an action on the plunger so as to switch the switch from a first electrical state to a second electrical state, characterized in that the movable member is a molded form projecting from a body of the device.
• the device is therefore particularly economical and simple to manufacture, the movable element being made by molding, using a plastic mold.
• the body may be any preferentially fixed area of the device. An action introduced on the cam is transmitted to the switch.

• Such a transmission mechanism is particularly reliable and effective, and simple to implement, a molded plastic shape that can easily include a bending zone capable of undergoing reversible deformation.
• the reception and action zones may be two opposite faces on either side of the movable element.
• the movable element is a tongue whose one end comprises an elastic deformable zone connected to the body, and a second end is free.
• the elastic deformable zone may be a flexural zone able to deform reversibly under the effect of a thrust of a cam.
• the action and reception zones can be the faces opposite of the second end of the tongue, the essential being that they are distant from the bending zone to allow a lever arm effect.
• the action of the mobile element applied to the plunger comprises a thrust made at an angle relative to the translation axis of the plunger less than 30 °. This makes it possible not to damage the switch, because this thrust at less than 30 ° induces few transverse stresses on the plunger.
• the body of the projecting device of which the movable member is molded is itself molded plastic. This facilitates the realization of the movable element because it is sufficient that it is performed in the same molding operation as the body, the movable element constituting a protrusion of the molded plastic body.
