The present invention relates to a switch device for opening and closing at least one electrical line, the device comprising: at least one pair of contact terminals; at least one drive member each drive member including a contact piece suitable for being displaced axially between a closed position in which the contact piece presses simultaneously against the two contact terminals of said at least one pair, interconnecting them electrically, and an open position in which the contact piece is spaced apart from said two contact terminals; and at least one actuator comprising an actuator element that is movable and suitable for driving said drive member(s); at least one of the actuator element and the drive member being connected to a stationary portion of said device by means of a generally flexible holding element, which element has at least one region secured to said stationary portion of the device, and at least one region secured to the actuator element or the drive member, which region is suitable for flexing relative to adjacent regions of the holding element so as to enable the actuator element or the drive member to be displaced substantially in rectilinear translation; wherein said at least one region secured to the actuator element or to the drive member is situated in a non-central region of the holding element.
1/ A switch device for opening and closing at least one electrical line, the device comprising:
2/ A device according to claim 1, wherein the holding element includes at least one flexible blade provided with a tongue cut out in said blade.
3/ A device according to claim 2, wherein the tongue is connected to the remainder of the blade in a region thereof that is adjacent to a free end of the blade.
4/ A device according to claim 1, wherein the holding element comprises a flexible return blade secured to an insulating pusher of a drive member, and wherein the device includes an electrically conductive closure plate provided with an orifice allowing said pusher to pass therethrough.
5/ A device according to claim 4, wherein said orifice presents a section selected in such a manner as to allow the pusher to pass through and move axially without friction.
6/ A device according to claim 4, wherein the flexible return blade is suitable for exerting a resilient return force that is sufficient to ensure that in the absence of a drive command being applied to the actuator element the contact piece comes to press against the closure plate.
7/ A device according to claim 4, wherein the flexible return blade is configured in such a manner that in the absence of a drive command being applied to the actuator element, the contact piece is situated in an intermediate position between its closed position and a position in which it bears against the closure plate.
8/ A device according to claim 4, wherein the flexible return blade is configured in such a manner that in the absence of a drive command applied to the actuator element, the contact piece comes to bear against the corresponding contact terminals.
9/ A device according to claim 4, wherein said flexible return blade is suitable for being secured directly to the actuator element.
10/ A device according to claim 9, wherein said flexible return blade and the actuator element co-operate via a connection of the rigid type.
11/ A device according to claim 9, wherein said flexible return blade and the actuator element co-operate via a connection of the non-rigid type.
12/ A device according to claim 9, wherein said flexible return blade includes a tongue whereby it is fixed to the actuator element.
13/ A device according to claim 4, wherein the actuator element is suitable for acting on the drive member via a flexible control blade distinct from said return blade, said control blade optionally including a tongue suitable for bearing against the pusher of said drive member.
14/ A device according to claim 1, wherein the actuator element has an axial top end and an axial bottom end, the top end at least being connected to a flexible holding element.
15/ A device according to claim 14, wherein the bottom end of the actuator element is connected to a flexible holding element.
16/ A device according to claim 1, having at least two drive members, the device including a flexible control blade suitable for acting simultaneously or in alternation of said at least two drive members.
17/ A device according to claim 16, wherein the control blade is configured as a return blade for the two drive members, the blade presenting two portions situated on either side of fixing regions for fixing the return blade to stationary portions of the device, each of the two portions of the blade being secured to a respective drive member, and wherein the actuator element is suitable for acting on one of said two portions so as to drive one of the two drive members towards the open position and the other towards the closed position.
18/ A device according to claim 16, wherein said control blade has two portions situated on either side of regions for fixing the control blade to fixed portions of the device, each of said two portions of the blade being suitable for acting on a corresponding drive member, the actuator element being fixed to the control blade in one of said two portions, and wherein each of the drive members is secured to a respective return blade distinct from the control blade.
19/ A device according to claim 1, including a flexible holding element provided with a plurality of blades, each enabling a drive member or an actuator element to be fixed, the holding element presenting in particular a shape that is invariant on being turned through an angle of 2π/n, where n is an integer, about an axis of rotation perpendicular to the plane of the blades.
