The present invention relates to an electric switch with rubbing contact () comprising on the one hand at least one fixed contact () and on the other hand at least one moving rubbing contact () that can move along a predefined trajectory and exhibiting a contact surface () intended to rub on said at least one fixed contact (), characterized in that at least said contact surface () is treated by ion bombardment by virtue of an ion beam, and in that the fixed () and moving () contacts are bare.

Electric switch with rubbing contact

The invention relates to a switching device for motor vehicle column top comprising a microcontroller (). The latter comprises at least two distinct functional switching blocks (), each block being linked to two signal inputs (e, e, e, e) and two signal outputs (a, b, c) of the microcontroller (), a signal output (a, b, c) or a signal input (e, e, e, e) of which is linked solely to a single functional block () and comprising four switches (), each switch () being linked to a signal input/output pair of the microcontroller () distinct from that of the other three of the same block (). At least two distinct functional switching blocks () share only either one signal output (a, b, c), or input (e, e, e, e) of the microcontroller (), and the microcontroller () is configured so as to deduce front a signal dispatched by at least one signal output (a, b, c) that has passed through at least one functional switching block () and has been received at at least one signal input (e, e, e, e), the state of switching of at least one switch () of a functional switching block ().

Switching device for the top-end of an automobile vehicle steering column

A contactor carriage fitted so as to move translationally in an electrical switch of a motor vehicle, in a unit providing controls under the steering wheel, in order to establish according to a user command, an electrical contact for one or more predefined positions of the path of the carriage is disclosed. The carriage has at least one electrical contacting emplacement, a first housing for accommodating a high-current contactor element and a second housing for accommodating a low-current contactor element. An electrical contact is established at said emplacement either by placing a high-current contactor element in the associated housing or by placing a low-current contactor element in said housing.

The invention relates to a rotatable indexing unit for a manual control member (), comprising two indexing components () one of which is the rotor () rotatably secured to said control member and the other is the stator () which is embodied in such a way that it is fixedly maintained with respect to the rotor. The rotor and the stator are mounted coaxially and comprise a plurality of angular segments () at least some of which are magnetised in such a way that they define stable and unstable positions for said control member, and the rotor and the stator have a conical or tapering shape which makes it possible to reduce the required radial space and increase the so-called active surfaces of interaction between the magnets.

Indexing unit and control device comprising such an indexing unit

The invention concerns a control assembly, in particular for motor vehicle steering column top portion (), comprising several switching modules () and a microcontroller () mounted on a motherboard () for interpreting a switching state based on the identifier of the module to deliver an appropriate control signal, the motherboard () having several connecting locations (EEEE), and each module () having an identical number N of predetermined tracks (LLLL, LIDIDCSCSCSCS) to be connected to tracks associated with the motherboard (). The corresponding exit tracks (LLLLLIDID) of each switching module () are interconnected and connected together on the same input of the microcontroller (), and the control assembly comprises for each location (EEEE) means for activating reading of a switching state of a module connected at said location, said activating means being monitored by the microcontroller ().
